The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations for assessing grade-level content. The assessments are aligned to grade-level standards. Examples include:

  • In Unit 5, Mid-Unit Assessment, Problem 5 provides a scenario in which bacteria is doubling over time. Students determine if the given population of bacteria is a function of the number of days. Students also determine if the function is linear and explain their reasoning (8.F.1). The problem reads, “Lin counts five bacteria under a microscope. She counts them again each day for four days, and finds that the number of bacteria doubled each day—from 5 to 10, then from 10 to 20, and so on. Is the population of bacteria a function of the number of days? If so, is it linear? Explain your reasoning.”
  • In Unit 7, End-of-Unit Assessment, Problem 2, students select all expressions that equal $$6^{-10}$$. The five choices are all variations of using the properties of exponents (8.EE.1).

Assessments are located on the first page of each unit in Lessons & Assessments, which is below Unit Overview, for each of the first eight units. Unit 9 is an optional unit and has no assessments. Assessments are limited to seven problems but are often broken into multiple prompts and assess numerous standards. Units 1 and 5 contain Mid-Unit Assessments for a total of 10 assessments.

The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations that supporting work enhances focus and coherence simultaneously by engaging students in the major work of the grade.

Supporting standards/clusters are connected to the major standards/clusters of the grade. Multiple lessons in the Grade 8 curriculum incorporate supporting standards in ways that support and/or maintain the focus on major work standards. Examples of the connections between supporting work and major work include the following:

  • In Unit 5, Lesson 17, students use volume formulas for three-dimensional figures to explore aspects of functions. Students compare functions presented as equations, graphs, and/or tables when exploring linear and nonlinear relationships. In the lesson Warm-Up, students determine if two quantities are functions by examining the distance a truck traveled in relation to the amount of gas used (8.F.1). Activities 3 and 4 address 8.F.1, 8.F.B, and 8.G.9 as: “Students continue working with functions to investigate what happens to the volume of a cylinder when you halve the height.” The lesson Cool-Down connects 8.G.C and 8.F.1 as students explore the height and volume of cylinders. In Lesson 18, students explore the effect on the volume of cylinders in functions where two variables are scaled. Students use volume formulas for cylinders and graphs of the functions in this exploration.
  • In Unit 6, the first three lessons introduce students to associations in two variables and how to display and analyze those associations using scatter plots (8.SP.2). In the Lesson 4 Warm-Up, students estimate the slope of a given line that lies close to, but not directly on, two points. During lesson activities, students state the meaning of the slope in the given contexts and also whether outliers have an effect on the slope of the line of best fit. Lessons 5 through 8 continue to build students' understanding of lines and slope (8.EE.5) to build an understanding of scatter plots and bivariate data.
  • In Unit 8, Lesson 3, Activities, students assess whether different rational numbers are solutions for square roots. In Lesson 4, students find solutions to functions that include square roots, and they estimate solutions to square roots in order to develop a deeper understanding of square roots as numbers and not just as solutions to the side length of a square when the area is known (8.NS.2, 8.EE.2).

Indicator Rating Details

The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations for being consistent with the progressions in the standards. The instructional materials clearly identify content from prior and future grade levels and use it to support the progressions of the grade-level standards. The instructional materials also relate grade-level concepts explicitly to prior knowledge from earlier grades.

The materials are intentionally designed to address the standards the way they are laid out in the progressions, and the full unit narrative in the Unit Overview describes how the standards and progressions are connected. Units begin with lessons connected to the standards from prior grades that are relevant to the current topic. Standards from the grade level and prior grades, and standards that will be addressed later in the year are identified in the sections as “addressing,” “building on,” and “building towards,” respectively. For example:

  • In Unit 3, Lesson 1, About this lesson states, “This lesson is the first of four where students work with proportional relationships from a Grade 8 perspective.” In the lesson, 7.RP.2 is identified as the standard that the lesson is “building on,” the standard the lesson is “addressing” is 8.EE.B, and the standard the lesson is “building toward” is 8.EE.5. According to the CCSSM progressions, the study of proportional relationships is a foundation for the study of functions. After Lesson 4, students move to linear relationships. The Lesson 5 Overview states, “After revisiting examples of proportional relationships in the previous lessons, this lesson is the first of four lessons that moves from proportional relationships to linear relationships with positive rates of change.”

The Warm-Ups in lessons frequently work with prior-grade standards in ways that support learning of grade-level problems and make connections to progressions from previous grades. For example:

  • Unit 3, Lessons 1 and 2 begin with looking at graphs and comparing proportional relationships (7.RP.2). The Lesson 1 Warm-Up has students compare graphs of proportional relationships with the same scale. The Lesson 2 Warm-Up includes different scales. Lessons 3 and 4 continue work with graphing proportional relationships with attention to graph features such as scale. Students pay attention to graph features in preparation for grade-level work with linear equations and graphs of linear equations.
  • The Unit 8, Lesson 3 (6.EE.4, 5.NF.4) Warm-Up includes practice with multiplying fractions (5.NF.4) which is essential in the lesson for estimating square roots. This connection is explicit in the teacher materials that state, “The purpose of this warm-up is for students to review multiplication of fractions in preparation for the main problem of this lesson: estimating solutions to the equation $$x^2=2$$. For example, 3⁄2 · 3⁄2 = 9⁄4, which is a value close to 2 so 3⁄2 is a value close to the $$\sqrt{2}$$.”

The instructional materials attend to the full intent of the grade-level standards by giving all students extensive work with grade-level problems.

In the Course Guide under Course Information and Scope and Sequence, there is a chart which accurately reflects the mathematics in the materials. All grade-level standards are represented across the 9 units. Tasks are aligned to grade-level work and are connected to prior-grade knowledge. For example:

  • In Unit 5, the Full unit narrative in the Unit Overview describes multiple ways that function understanding is developed by building upon prior-grade work, including input/output patterns in Grades 4 and 5, independent and dependent variables in Grade 6, work with ratios and proportions in Grades 6 through 8, and work with geometric measurement as early as Kindergarten. Students explore linear relationships built from work early in Units 1 and 2 with similarity of triangles. The unit develops from exploring input/output patterns in order to develop a formal understanding of the definition of a function in Lessons 1 and 2, to exploring different representations of functions in Lessons 3 through 7. This work includes verbal descriptions, equations, tables, and graphs. Multiple representations are used in each lesson. The lessons near the end of the unit work with volume formulas. Lesson 22, the final lesson in the unit, explicitly connects work with functions to volume and includes exposure to non-linear functions.
  • In Unit 4, Lesson 13 consists of problems where students use graphs of systems of linear equations to reason about the solutions to equations. The first activity has students match the graph with the system of equations, then students work on a digital graph to find solutions to a system of equations. In the second activity, the students look at six different graphic representations of systems of equations and discuss the meaning of having no solution, one solution, or infinite solutions. In the Cool-Down, students look at the graphic representation of a system of equations and give possible solutions based on what the graph looks like. There are also five practice problems that are connected to the lesson.

A typical lesson has a Warm-Up, one or more Activities, and a Cool-Down. Additionally, every lesson provides practice problems that can be used as independent or group work. Some lessons also provide an “Are you ready for more?” problem. These problems are an opportunity for students to explore grade-level mathematics in more depth and often make connections between the topic in the lesson and other concepts at grade level. They are intended to be used on an opt-in basis by students if they finish the main class activity early or want to do more mathematics on their own.

The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations for fostering coherence through connections at a single grade, where appropriate and required by the standards.

Materials include learning objectives that are visibly shaped by CCSSM cluster headings, including:

8.EE.C Analyze and solve linear equations and pairs of simultaneous linear equations.

  • The Unit 4 Overview describes how work in solving linear equations builds on work from Grades 6 and 7 with equations and expressions in one variable, then further builds to algebraic methods for solving equations. The Lesson 10 learning targets state: “Make connections between ordered pairs in tables and graphs,” and “Given descriptions of two linear relationships, interpret ordered pairs in contexts, focusing on when or where the same ordered pair makes each relationship true.” The Lesson 13 learning targets are also connected to the cluster heading, including: “Understand that a system of equations can have no solutions, one solution, or infinitely many solutions.” “Connect features of the graphs to the number of solutions the system has.” and “Start solving systems algebraically.”

8.G.C Solve real-world and mathematical problems involving volume of cylinders, cones, and spheres.

  • The Unit 5 Overview details the progression of geometric measurement from Kindergarten and lays out how the unit will extend concepts of volume to deepen students' understanding of the geometric features of three-dimensional shapes such as radii, bases, and heights. In addition, the unit integrates student work with functions as they develop a conceptual understanding of formulas for volume. All Unit 5 lessons include real-world or mathematical problems. Sample learning goals aligned to the cluster heading include: “Find volumes of cones in mathematical and real-world problems” in Lesson 15 and “Solve a variety of mathematical and real-world problems about the volume of a cylinder, cone, or sphere” in Lesson 21.

The materials include problems and activities that connect two or more clusters in a domain, or two or more domains in a grade, in cases where these connections are natural and important. Multiple examples of tasks connecting standards within and across clusters and domains are present.

  • In Unit 5, Lesson 8, Activities 2 and 3, students model real-world problems with functions by interpreting the start value and the slope (8.F.B). This includes understanding linear equations as describing linear functions and involves comparing different representations of a function, with an emphasis on equations and graphs, but also includes verbal/written descriptions of the real-world scenario (8.F.A).
  • In Unit 8, Lesson 2, 8.EE.A and 8.F.B are connected as students take measurements of area and side lengths, collect data, and determine $$y=x^2$$ as a function that models the relationship between area of a square and a side length. Students make estimates of side lengths given the area of a square and begin to use square root symbols and terms.
  • In Unit 8, Lesson 3, 8.G.A and 8.EE.B are connected. The Warm-Up task reviews 8.G.A.1 where students must identify lines that have been translated from a given line. The rest of the lesson addresses 8.EE.B with an emphasis on students using their understanding of translations to derive y = mx + b from a graph of y = mx. The series of tasks use contexts to help students make connections to the equation of a line and how translations can be helpful in interpretation in context.

Indicator Rating Details

The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations for developing conceptual understanding of key mathematical concepts, especially where called for in specific standards or cluster headings. The materials include problems and questions that develop conceptual understanding throughout the grade level, and multiple opportunities exist for students to access concepts from different perspectives and independently demonstrate conceptual understanding throughout the grade.

In Unit 5, students define, evaluate, and compare functions (8.F.A), for example:

  • Lesson 1 begins to develop the “idea of a function as a rule that assigns to each allowable input exactly one output.” In the first Activity of Lesson 1, students play "Guess My Rule" in an applet. Students enter any input value into Column A of the spreadsheet found in the applet, and the resulting output appears in Column B. Students generate a rule after completing as many iterations as needed. Functions' rules include additive, multiplicative, and exponential patterns.
  • In Lesson 2, function language is introduced as students identify examples and nonexamples of functions in order to extend the idea that the output is dependent on the input. In the first Activity, students answer: “A number is 5. Do you know its square?” and the anticipated response is given as, “Yes, the square of 5 is 25.” Another prompt states, “The square of a number is 16. Do you know the number?” resulting in the anticipated response, “No, there are two different numbers whose square is 16, namely 4 and -4.” The term “function” is not introduced until the second Activity in which students use function language to express whether the given scenarios from the previous Activity are functions. The corresponding exemplar statements from the given examples are, “Yes, the square of a number depends on the number,” and “No, knowing the square of a number does not determine the number.”
  • In Lesson 4, second Activity, students examine three, unlabeled continuous graphs in order to make connections between representations. They choose the matching equation and context (8.F.3), use the context to identify the dependent and independent variables, use the graph to identify the output when the input is 1, and interpret what that tells you about each situation in prompt 3 (8.F.1). The graphs include a non-linear representation and two linear functions, one with positive slope and one with negative slope.

Unit 1, which begins with transformations, 2 addresses congruence using physical models, transparencies, or geometry software (8.G.A).

  • In Lessons 1 through 6, students spend most of the instructional time either physically moving shapes or imitating that movement in GeoGebra. In Lesson 1, students examine transformations as a way of moving objects in a plane, and in Lesson 2, students define these movements in their own words.
  • Lessons 11 through 13 explore congruence. In the Lesson 12 Warm-Up, students are given a variety of congruent triangles in different orientations and the following prompt: “All of these triangles are congruent. Sometimes we can take one figure to another with a translation. Shade the triangles that are images of triangle ABC under a translation.” Students develop the concept that a two-dimensional figure is congruent to another two-dimensional figure if the second can be obtained from the first by a sequence of transformations. The idea of “rotations and reflections usually (but not always) change the orientation of a figure” is discussed and further explored when students name a sequence of transformations to prove some of the non-shaded triangles congruent to triangle ABC.

In Lessons 14 through 16, students establish informal arguments about angles. The second Activity in Lesson 14 states, "Lines ℓ and k are parallel, and t is a transversal. Point M is the midpoint of segment PQ.” Students use tracing paper to “Find a rigid transformation showing that angles MPA and MQB are congruent.”

Indicator Rating Details

The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations for attending to those standards that set an expectation of procedural skill. Materials attend to the Grade 8 expected procedural skills, particularly those related to solving linear equations and systems of equations.

Procedural skills and fluencies develop with conceptual understanding and are built upon work students have accomplished with operations and equations from prior grades. Students practice developed procedures throughout practice problem sets that follow the units, and students use emerging fluencies in the context of solving problems. According to the Design Principles within the Grade 8 Course Guide within each unit, “Students are systematically introduced to representations, contexts, language, and notation. As their learning progresses, they see and understand more efficient methods of solving problems, supporting the shift towards procedural fluency.” Number Talks included in many Warm-Ups often revisit fluencies developed in earlier grades and specifically relate to the Activities found in the lessons. Additionally, students demonstrate procedural skills throughout the year in a variety of practice problems. Examples of practice problems include:

8.EE.7 is addressed in Unit 4 as students develop procedural skill in solving linear equations in one variable, and students practice this skill in Unit 5.

  • In Unit 4, Lesson 3 Warm-Up, students match hanger diagrams to equations and variables to their respective shapes within the diagram. Next, students begin to match the first “moves” in solving equations in the first Activity. In the additional activities in Lesson 3, students “[think] about strategically solving equations by paying attention to their structure” when they are presented two student work samples to evaluate and provide recommendations for solving.
  • In Unit 4, Lesson 4, there is a mix of tasks that focuses on practicing solving equations such as matching, choosing solution steps, evaluating the work of sample student solution paths, as well as assessing similarities and looking for mistakes.
  • In Unit 4, Lesson 5, students move toward a general method for solving linear equations using mental math to solve one-step equations for a variable on one side and then work with a partner to justify their steps with one another between each step.
  • In Unit 4, Lesson 6, Strategic Solving states: “In this lesson, students learn to stop and think ahead strategically before plunging into a solution method. After a Warm-Up in which they construct their own equation to solve a problem, they look at equations with different structures and decide whether the solution will be positive, negative, or zero, without solving the equation. They judge which equations are likely to be easy to solve and which are likely to be difficult.” In the following lessons, students examine situations when an equation has many or no solutions.
  • In Unit 5, Lesson 3, students solve and check the solutions to multi-step equations such as 4z + 5 = -3z − 8. In Lesson 7, students solve and check the solution to the multi-step equation -(-2x + 1) = 9 − 14x. In Lesson 9 Problem 3, students solve and explain the reasoning leading to the solutions of multi-step equations such as 4(2a + 2) = 8(2 − 3a).

Systems of equations (8.EE.8b) are formally introduced in the latter part of Unit 4 after students solve linear equations in one variable (8.EE.7), including writing, solving, and graphing equations as well as deciding what it means for an equation to be true. Students learn to interpret and solve systems of equations in Lessons 12 through 15 in preparation for applying their procedural knowledge in Lesson 16.

  • In the Lesson 12 Warm-Up, students examine a situation and determine the features of the graph of the situation without actually graphing. All tasks involve graphing equations and discussing solutions in context of graphs. The term “system of equations” is introduced. Also in Lesson 12, students solve a system of two equations, both in slope-intercept form.
  • In the Lesson 14 Warm-Up, students use substitution strategies to mentally solve systems of equations. In Activity 1, students analyze the structure of a system of equations before deciding on an efficient solution path. The equations lend themselves to suggesting substitution as the first step toward finding a solution and develop the procedure for substituting an expression in place of a variable.
  • In Lesson 15, students write and interpret systems of equations from contexts with rational coefficients and continue to practice solving using various methods, including: “[Solving] the systems to find the number of solutions; [Using] the slope and y-intercept to determine the number of solutions; [Manipulating] the equations into another form, then compare the equations. [Noticing] that the left side of the second equation in system C is double the left side of the first equation, but the right side is not.”
  • In Lesson 20, students write and solve a system of equations representing the context given about a bicycle shop inventory in order to find the number of bicycles in the store.

Indicator Rating Details

The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations for being designed so that teachers and students spend sufficient time working with engaging applications of the mathematics. Engaging applications include single and multi-step problems, both routine and non-routine, presented in a context in which the mathematics is applied. Applications occur throughout the materials and are used throughout the curriculum to build conceptual understanding, for example:

In Unit 5, Lessons 5 through 11, students model relationships with functions by identifying and creating tables, graphs, and equations (8.F.B).

  • The Lesson 6 Warm-Up states: “The purpose of this Warm-Up is for students to realize there are different dependent variables that can be used when making a model of a context, and the choice of which we use affects how a graph of a function looks.” Students view five photographs of a dog taken at equal intervals of time and two graphs representing the scenario. Both graphs have the same independent variable but look dramatically different. Students determine how the dependent variable represents the perspective of the graph.
  • In the Lesson 10 Warm-Up, students share what they notice on a graph of temperature data during different parts of the day. In Activity 1, they use piecewise linear graphs to find information about the real-life situation they represent. In Activity 2, students analyze a situation to calculate the rate of change.
  • In Lesson 11, Activity 1, students investigate how the height of water in a graduated cylinder is a function of the volume of water in the graduated cylinder. Students make predictions about how the graph will look,  test their prediction by filling the graduated cylinder with different amounts of water, and gather and graph the data. Students use an applet to reason about the height of the water in a given cylinder. They graph the relationship and explain the meaning of specific points in their recorded data. Students use the context of the given cylinder in the graph to determine, “What would the endpoint of the graph be?” In the next phase of the Activity, students compare this relationship to ones in which the radius of the cylinder has been modified and explain how the slope is less steep in the given graphic representation.

In Unit 4, students solve real-world and mathematical problems leading to two linear equations in two variables (8.EE.8c). Lesson 16 includes opportunities for students to investigate applications of systems of equations.

  • In Activity 1, students solve problems involving real-world contexts. For the first problem, students find the time at which two friends will meet if they are cycling toward one another. In the second problem, they determine how many grapefruits are sold if students are selling both grapefruits and nuts. The price of both items is given as well as the total number of items sold and the total money made in the fundraiser. In the third problem, students find the number of hours Andre and Jada must work to make the same amount of money when working different jobs and getting paid different rates. In each problem, students “explain or show [their] reasoning.” After engaging in these problems, students create their own situation and solve. These scenarios are then exchanged for other pairs of students to solve.

The instructional materials for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations that the three aspects of rigor are not always treated together and are not always treated separately. The materials address aspects of rigor independently, and there are instances when multiple aspects of rigor are used to support student learning and mastery of the standards. There are multiple lessons where one aspect of rigor is emphasized.

Examples of conceptual understanding include:

  • In Unit 1, Lesson 3, Activity 1, students are given four figures on a grid and told: “In Figure 1, translate triangle ABC so that A goes to A′. In Figure 2, translate triangle ABC so that C goes to C′. In Figure 3, rotate triangle ABC 90 counterclockwise using center O. In Figure 4, reflect triangle ABC using line l.” Activities similar to this are done repeatedly throughout the beginning lessons of Unit 1. Eventually, students use this information to draw conclusions about congruent figures, angles, and similar figures (8.G.A).
  • In Unit 5 Lesson 6, students demonstrate conceptual understanding of graphs as they relate to context and determine the scale to represent the independent and dependent variables. Students create graphs for a given story/context determining the scale. Discussion questions include: “Which quantity is a function of which? Explain your reasoning." "Based on your graph, is his friend’s house or the park closer to Noah's home? Explain how you know." and, "Read the story and all your responses again. Does everything make sense? If not, make changes to your work.”

Examples of procedural skills include:

  • In Unit 4, Lesson 5, students develop procedural skill solving equations with one variable. During the Warm-Up, students solve the following equations mentally: 5 − x = 8, -1 = x − 2, -3x = 9, and -10 = -5x. In the first Activity, students are given a card with a more complex equation on it and told to work with a partner, taking turns after each step to solve the equation. They solve equations on four cards in all.
  • In Unit 5, Lesson 16 Warm-Up, students develop skills using the formula for volume to solve: “27 = (1⁄3)h, 27 = (1⁄3)$$r^2$$, 12π= ( 1⁄3)πa, 12π = (1⁄3)π$$b^2$$.” In the first Activity, students practice finding relevant information and completing tables to apply the volume formula to find the value of unknown dimensions.

Examples of application include:

  • In Unit 2, Lesson 13, Activity 3, students apply their understanding of proportional relationships and arguments establishing facts about similar triangles and angle relationships (8.G.5) to estimate the height of a tall object that cannot be measured directly. Students devise a method to estimate, justify, and test their estimate.
  • In Unit 5, Lesson 21, students solve a variety of mathematical problems involving finding the volume of cones, cylinders, rectangular prisms, and spheres in the given figures (8.G.9).

Examples of lessons where two or three aspects of rigor are connected include:

  • In Unit 5, Lessons 3 through 7, students develop their understanding of functions by comparing multiple representations. The majority of Activities use real-world contexts with frequent opportunities for students to interpret functions and their representations in specific contexts.
  • The Practice Problems available for each lesson are arranged so that students practice and develop skills for a concept and engage with more complex applications. Typically, there are six problems included in the practice problems. Procedural practice, visual representations, contexts, and/or standard methods of solving said problems are present.

Indicator Rating Details

The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations that the Standards for Mathematical Practice are identified and used to enrich mathematics content within and throughout the grade level. All eight MPs are clearly identified throughout the materials. The MPs are initially identified in the Course Guide under the full unit narrative description of each unit within the Course Information, for example:

  • In Unit 2, excerpts from the full unit narrative include: “Through activities designed and sequenced to allow students to make sense of problems and persevere in solving them (MP1), students use and extend their knowledge of geometry and geometric measurement.” Further, in the full lesson narrative it states, “They use the definition of 'similar' and properties of similar figures to justify claims of similarity or non-similarity and to reason about similar figures (MP3)."
  • In Unit 6, the full lesson narrative states: “[Students] return to the data on height and arm span gathered at the beginning of the unit, describe the association between the two, and fit a line to the data (MP4). The third section focuses on using two-way tables to analyze categorical data (MP4). Students use a two-way frequency table to create a relative frequency table to examine the percentages represented in each intersection of categories to look for any associations between the categories. Students also examine and create bar and segmented bar graphs to visualize any associations.”

Within a lesson, the MPs are identified within the teaching notes accompanying the lesson in general or before each of the activities. Teaching Notes often highlight when a Math Practice is particularly important for a concept or when a task may exemplify the identified Practice, for example:

  • In Unit 1, Lesson 14, the About the lesson states, “One Mathematical Practice that is particularly relevant for this lesson is MP8. Students will notice as they calculate angles that they are repeatedly using vertical and adjacent angles and that often they have a choice which method to apply. They will also notice that the angles made by parallel lines cut by a transversal are the same and this observation is the key structure in this lesson.”
  • In Unit 2, Lesson 2, About the lesson discusses developing the idea of dilations by providing tools for students: “As with previous geometry lessons, students should have access to geometry toolkits so they can make strategic choices about which tools to use (MP5).”
  • In Unit 4, Lesson 5, Teaching Notes accompanying Activity 1 states, “The goal of this Activity is for students to build fluency solving equations with variables on each side. Students describe each step in their solution process to a partner and justify how each of their changes maintains the equality of the two expressions (MP3).”
  • In Unit 5, Lesson 3, Warm-Up Teaching Notes states: “The purpose of this Warm-Up is for students to use repeated reasoning to write an algebraic expression to represent a rule of a function (MP8).”

The MPs are used to enrich the mathematical content and are not treated separately from the content in stand-alone lessons. MPs are highlighted and discussed throughout the lesson narratives to support a teacher’s understanding of the MP itself as the teacher is provided direction regarding how the content is connected to the MP, for example:

  • In Unit 1, Lesson 13, About this lesson, the connection of MP6 to 8.G.2 is explained: “One of the mathematical practices that takes center stage in this lesson is MP6. For congruent figures built out of several different parts (for example, a collection of circles), the distances between all pairs of points must be the same. It is not enough that the constituent parts (circles, for example) be congruent: they must also be in the same configuration, the same distance apart. This follows from the definition of congruence: rigid motions do not change distances between points, so if Figure 1 is congruent to Figure 2 then the distance between any pair of points in Figure 1 is equal to the distance between the corresponding pair of points in Figure 2.”
  • In Unit 9, Lesson 2, students extend their knowledge of transformations into the creation of a tessellation. The Teaching notes for the second Activity states, “Students look for and make use of structure (MP7), both when they try to put copies of the shape together to build a tessellation and when they examine whether or not it is possible to construct a different tessellation.”

The MPs are not identified in the student materials, however, there are questions posed with activities that engage students with MPs. For example, in Unit 9, Lesson 1, Additional materials, Digital applets, the student-facing directions state: “With your partner, choose one of the six shapes in the toolbar that you will both use. 1) Select the shape tool by clicking on it. Create copies of your shape by clicking in the work space. 2) When you have enough to work with, click on the Move tool (the arrow) to drag or turn them. 3) If you have trouble aligning the shapes, right click to turn on the grid.” After they have finished, the discussion prompts lead students to find structure in the patterns, “Compare your tessellation to your partner’s. How are they similar? How are they different?”

The instructional materials reviewed for LearnZillion Illustrative Mathematics 6-8 Math, Grade 8 meet expectations for carefully attending to the full meaning of each practice standard. The materials attend to the full meaning of each of the 8 MPs. The MPs are discussed in both the unit and lesson narratives, as appropriate, when they relate to the overall work. They are also explained within individual activities, when necessary. Over the course of the year, students have multiple opportunities to engage with the full meaning of each MP. Examples include:

MP1 - Make sense of problems and persevere in solving them.

  • In Unit 1, Lesson 6, 6.2 Activity, students “make sense of problems by determining what information is necessary, and then ask for information they need to solve it. This may take several rounds of discussion if their first requests do not yield the information they need.” The following instructions are provided for the teacher: “Tell students they will continue to describe transformations using coordinates. Explain the Info Gap structure, and consider demonstrating the protocol if students are unfamiliar with it. Arrange students in groups of two. Provide access to graph paper. In each group, distribute a problem card to one student and a data card to the other student. They need to know which transformations were applied (i.e., translation, rotation, or reflection). They need to determine the order in which the transformations were applied. They need to remember what information is needed to describe a translation, rotation, or reflection.”
  • In Unit 5, Lesson 21, Activity 3, students engage in another Info Gap activity. One student is given a card that has a question related to volume equations of cylinders, cones, and spheres. The other student is given a card with all the information needed to answer the question. The student with the question asks the student with the data a series of questions that will give them the necessary information to solve the problem. It may take several rounds of discussion if their first requests do not yield the information they need, creating a situation in which students have to persevere to solve a problem.

MP2 - Reason abstractly and quantitatively.

  • In Unit 5, Lesson 7, Activity 4, students compare properties of functions represented in different ways. Students are given a verbal description and a table to compare and decide whose family traveled farther over the same time intervals. The purpose of this activity is for students to interpret and compare functions.
  • In Unit 7, students reason abstractly and quantitatively to solve problems involving operations with exponents. For example, in Lesson 2, 2.2 Activity, students are given three base ten blocks: a hundred block, a ten block, and a one block. They must answer several questions: “If each small square represents $$10^2$$, then what does the medium rectangle represent? The large square?” Additional questions change the chosen square and power of 10. The visual element provides both an abstract and quantitative entry point to the problem as students are introduced to the Laws of Exponents.

MP4 - Model with mathematics.

  • In Unit 2, Lesson 13, students model a real-world context with similar triangles to find the height of an unknown object. Students examine the length of shadows of different objects to find that a proportional relationship exists between the height of the object and the length of its shadow. Students use their knowledge of similar triangles and the hypothesis that the rays of sunlight making the shadows are parallel to justify the proportional relationship between the object and its shadow. Students then go outside and make their own measurements of different objects and the lengths of their shadows and use this technique to estimate the height of these objects.
  • In Unit 6, Lesson 8, 8.3 Activity, students model and analyze data related to arm span and height measurements that were gathered in a previous lesson. The students create a scatter plot, identify and explain outliers, and explain whether the equation y = x is a good fit for the data. This activity is an opportunity for students to explore bivariate data that occurs in the real world and and is related to themselves.

MP5 - Use appropriate tools strategically.

  • In Unit 1, lesson plans suggest that each student have access to a geometry toolkit. These contain tracing paper, graph paper, colored pencils, scissors, ruler, protractor, and an index card to use as a straightedge or to mark right angles, giving students opportunities to select appropriate tools and use them strategically to solve problems. Lessons in this unit ensure the full depth of this MP by emphasizing choice. For example, the Lesson 1 Overview states: “To make strategic choices about when to use which tools (MP5), students need to have opportunities to make those choices. Apps and simulations should supplement rather than replace physical tools.” In the Lesson 14 Warm-Up, the narrative includes the following guidance for teachers: “Some students may wish to use protractors, either to double check work or to investigate the different angle measures. This is an appropriate use of technology (MP5), but ask these students what other methods they could use instead.”
  • In Unit 7, Lesson 10, students have opportunities to use digital tools and number lines, using them to think about how to rewrite expressions with exponents. In 10.3 Activity, students are given a table showing how fast light waves or electricity can travel through different materials and a number line applet labeled 0, 1 x $$10^8$$, 2 x $$10^8$$, … 9 x $$10^8$$, 1 x $$10^9$$ with a magnifier that will expand the space between any two consecutive numbers. The students must convert the given speeds to a usable format and plot them on the given number line(s) as precisely as possible.

MP7 - Look for and make use of structure.

  • In Unit 7, Lesson 3, students look for patterns when 10 is raised to a power so that numerical expressions can be written with a single exponent, such as $$10 \cdot 10^3 = 10^4$$. In Lesson 6, students analyze the structure of exponents to make sense of expressions with multiple bases.
  • In Unit 2, Lesson 11, 11.3 Activity, students have already generated a rule to determine whether or not a point with coordinates (x, y) lies on a certain line when the line represents a proportional relationship. In this activity, students find a rule to determine if a point (x, y) lies on a line that does not pass through (0,0). Students use the structure of a line and properties of similar triangles to investigate rules relating pairs of coordinates on a line.

MP8 - Look for and express regularity in repeated reasoning.

  • In Unit 3, Lesson 8, students write equations of lines using y = mx + b. In this lesson and the ones that lead up to this, students develop their understanding based on repeated reasoning about equations of lines. In a previous lesson, students wrote an equation of a line by making generalizations from repeated calculations using their understanding of similar triangles and slope. Additionally, they have written an equation of a linear relationship by reasoning about initial values and rates of change and have graphed the equation as a line in the plane. In this lesson, they develop the idea that any line in the plane can be considered a vertical translation of a line through the origin.
  • In Unit 7, Lesson 3, students explore the idea that repeated division by two is equivalent to repeated multiplication by 1/2. This allows students to make sense of negative exponents later in Lesson 3, where students look for patterns when bases of 10 are raised to a power in the given chart. Finally, in Lesson 5, students use repeated reasoning to recognize that negative powers of 10 represent repeated multiplication of 1/10.

Students explain their reasoning and compare their strategies for solving in small group and whole class settings, and examples include:

  • In Unit 2, Lesson 6, Cool-Down, students analyze and correct a series of transformations and a dilation intended to provide a similar figure. In Lesson 7, first Activity, students analyze two figures that are reported to be similar. Students justify or deny the claim; they build reasoning as to what characteristics are found in polygons that are not similar.
  • In Unit 5, Lesson 4, first Activity, students answer, “For each function: What is the output when the input is 1? What does this tell you about the situation? Label the corresponding point on the graph. Find two more input-output pairs. What do they tell you about the situation? Label the corresponding points on the graph.” Questions such as these are present throughout the lessons, providing students the opportunity to construct viable arguments in both verbal and written form.

  • The Unit 3, Lesson 5 Warm-Up provides guiding questions in the Activity Synthesis to help students practice MP3. This strategy is used repeatedly throughout the teacher materials. “To involve more students in the conversation, consider asking: Who can restate ____’s reasoning in a different way? Did anyone solve the problem the same way but would explain it differently? Did anyone solve the problem in a different way? Does anyone want to add on to ____’s strategy? Do you agree or disagree? Why?”
  • The Unit 6, Lesson 10 second Activity provides guidance to the teacher during the observation of small groups using data displays to find a bivariate association. “As students work, identify groups that use the different segmented bar graphs to explain why there is an association between the color of the eraser and flaws…Select previously identified groups to share their explanation for noticing an association.”
  • In Unit 3, Lesson 11, Activity 1, students explore vertical and horizontal lines in the coordinate plane. Teachers are prompted to: “...pause their work after question 2 and discuss which equation makes sense and why.”
  • In Unit 1, Lesson 11, 11.2 Synthesis, teachers facilitate a discussion to promote student debate so students can identify reasons and construct arguments as well as critique/analyze responses from others. The teacher guidance also provides ways to help students analyze/critique other’s arguments if it does not occur naturally by providing the teacher examples of what to say/suggest to promote more discourse: “For each pair of shapes, poll the class. Count how many students decided each pair was the same or not the same. Then for each pair of shapes, select at least one student to defend their reasoning.” Sample responses are provided for the teacher.

  • Both the unit and lesson narratives contain specific guidance for the teacher on methods to support students to communicate mathematically. Within the lesson narratives, new terms are in bold print and explained as related to the context of the material.
  • Unit 1 develops the concept of Rigid Transformations. In the initial lessons, students use their own words to describe moving one figure to another. As the unit progresses, students build their understanding of transformations and name these movements with the proper terminology (translations, reflections, rotations).
  • In Unit 6, Lessons 1 through 6 introduce scatter plots and related terminology. In Lessons 1 through 3, students are introduced to the definition of scatter plot, and they explore data represented by a scatter plot and the meaning of a specific point on a graph. In Lesson 4, the term outlier is introduced. In Lesson 5, students learn to explain trends in scatter plots, and in Lesson 6, they determine the slope of the “linear model”. Each lesson builds on the initial definition of scatter plot until students work with all aspects of them, understand the concept, and use related terminology.

No examples of incorrect use of vocabulary, symbols, or numbers were found within the materials.

The materials draw on research to explain and contextualize instructional routines and lesson activities. The Curriculum Guide includes specific links to research, for example:

  • “Selected activities are structured using Five Practices for Orchestrating Productive Mathematical Discussions (Smith & Stein, 2011), also described in Principles to Actions: Ensuring Mathematical Success for All (NCTM, 2014), and Intentional Talk: How to Structure and Lead Productive Mathematical Discussions (Kazemi & Hintz, 2014).”
  • The Design Principles: “Some of the instructional routines, known as Mathematical Language Routines (MLR), were developed by the Stanford University UL/SCALE team.”

In the Curriculum Guide, all of the “Instructional Routines” are fully explained.

  • Algebra Talks found in the Warm-Ups set a routine for collecting different strategies. “Algebra Talks build algebraic thinking by encouraging students to think about the numbers and variables in an expression and rely on what they know about structure, patterns, and properties of operations to mentally solve a problem. Algebra Talks promote seeing structure in expressions and thinking about how changing one number affects others in an equation. While participating in these activities, students need to be precise in their word choice and use of language (MP6).”
  • Think-Pair-Share routines found in the Lesson Activities provide structure for engaging students in collaboration. “This is a teaching routine useful in many contexts whose purpose is to give all students enough time to think about a prompt and form a response before they are expected to try to verbalize their thinking. First they have an opportunity to share their thinking in a low-stakes way with one partner, so that when they share with the class they can feel calm and confident, as well as say something meaningful that might advance everyone’s understanding. Additionally, the teacher has an opportunity to eavesdrop on the partner conversations so that she can purposefully select students to share with the class.”

The ELL Design is highlighted in the Teacher Guide and embodies the Understanding Language/SCALE Framework from the Stanford University Graduate School of Education, which consists of four principles: Support Sense-Making, Optimize Outputs, Cultivate Conversation, and Maximize Meta-Awareness. In addition, there are eight Mathematical Language Routines (MLR) that were included “because they are the most effective and practical for simultaneously learning mathematical practices, content, and language.” "A Mathematical Language Routine refers to a structured but adaptable format for amplifying, accessing, and developing students’ language."

In addition, “ELL Enhanced Lessons” are identified in the Unit Overview. These lessons highlight specific strategies for students who have a language barrier which affects their ability to participate in a given task. Throughout lessons, the use of one of a variety of instructional routines is designed to assist students in developing full understanding of math concepts and terminology. These Mathematical Language Routines include:

  • MLR2, Collect and Display, in which “the teacher listens for, and scribes, the student output using written words, diagrams and pictures; this collected output can be organized, revoiced, or explicitly connected to other language in a display for all students to use.”
  • MLR5, Co-Craft Questions and Problems, which “[allows] students to get inside of a context before feeling pressure to produce answers, and to create space for students to produce the language of mathematical questions themselves.”
  • MLR7, Compare and Connect, which “[fosters] students’ meta-awareness as they identify, compare, and contrast different mathematical approaches, representations, and language.”

In addition, lesson narratives include strategies designed to assist other special populations of students in completing specific tasks. Examples of these supports for students with disabilities include:

  • Social-Emotional Functioning: Peer Tutors. Pair students with their previously identified peer tutors.
  • Conceptual Processing: Eliminate Barriers. Assist students in seeing the connections between new problems and prior work. Students may benefit from a review of different representations to activate prior knowledge.
  • Conceptual Processing: Processing Time. Check in with individual students as needed to assess for comprehension during each step of the activity.
  • Executive Functioning: Graphic Organizers. Provide a t-chart for students to record what they notice and wonder prior to being expected to share these ideas with others.
  • Memory: Processing Time. Provide students with a number line that includes rational numbers.
  • Visual-Spatial Processing: Visual Aids. Provide handouts of the representations for students to draw on or highlight.

About Publishers Responses

All publishers are invited to provide an orientation to the educator-led team that will be reviewing their materials. The review teams also can ask publishers clarifying questions about their programs throughout the review process.

Once a review is complete, publishers have the opportunity to post a 1,500-word response to the educator report and a 1,500-word document that includes any background information or research on the instructional materials.

About Technology Information

EdReports requested that publishers fill out The Instructional Materials Technology Information document about each of their products that met our alignment criteria. This document does not evaluate the quality or desirability of any product functionality, but documents features in order to empower local schools and districts with information to select materials that will work best for them given their technological capabilities and instructional vision.

Please note: Beginning in spring 2020, reports developed by EdReports.org will be using an updated version of our review tools. View draft versions of our revised review criteria here.

Educator-Led Review Teams

Each report found on EdReports.org represents hundreds of hours of work by educator reviewers. Working in teams of 4-5, reviewers use educator-developed review tools, evidence guides, and key documents to thoroughly examine their sets of materials.

After receiving over 25 hours of training on the EdReports.org review tool and process, teams meet weekly over the course of several months to share evidence, come to consensus on scoring, and write the evidence that ultimately is shared on the website.

All team members look at every grade and indicator, ensuring that the entire team considers the program in full. The team lead and calibrator also meet in cross-team PLCs to ensure that the tool is being applied consistently among review teams. Final reports are the result of multiple educators analyzing every page, calibrating all findings, and reaching a unified conclusion.

Rubric Design

The EdReports.org’s rubric supports a sequential review process through three gateways. These gateways reflect the importance of standards alignment to the fundamental design elements of the materials and considers other attributes of high-quality curriculum as recommended by educators.

Advancing Through Gateways

  • Materials must meet or partially meet expectations for the first set of indicators to move along the process. Gateways 1 and 2 focus on questions of alignment. Are the instructional materials aligned to the standards? Are all standards present and treated with appropriate depth and quality required to support student learning?
  • Gateway 3 focuses on the question of usability. Are the instructional materials user-friendly for students and educators? Materials must be well designed to facilitate student learning and enhance a teacher’s ability to differentiate and build knowledge within the classroom. In order to be reviewed and attain a rating for usability (Gateway 3), the instructional materials must first meet expectations for alignment (Gateways 1 and 2).

Key Terms Used throughout Review Rubric and Reports

  • Indicator Specific item that reviewers look for in materials.
  • Criterion Combination of all of the individual indicators for a single focus area.
  • Gateway Organizing feature of the evaluation rubric that combines criteria and prioritizes order for sequential review.
  • Alignment Rating Degree to which materials meet expectations for alignment, including that all standards are present and treated with the appropriate depth to support students in learning the skills and knowledge that they need to be ready for college and career.
  • Usability Degree to which materials are consistent with effective practices for use and design, teacher planning and learning, assessment, and differentiated instruction.

Math K-8 Rubric and Evidence Guides

The K-8 review rubric identifies the criteria and indicators for high quality instructional materials. The rubric supports a sequential review process that reflect the importance of alignment to the standards then consider other high-quality attributes of curriculum as recommended by educators.

For math, our rubrics evaluate materials based on:

  • Focus and Coherence

  • Rigor and Mathematical Practices

  • Instructional Supports and Usability

The K-8 Evidence Guides complement the rubric by elaborating details for each indicator including the purpose of the indicator, information on how to collect evidence, guiding questions and discussion prompts, and scoring criteria.

Content for Illustrative Mathematics 6-8 Math was developed by Open Up Resources and authored by Illustrative Mathematics. LearnZillion Illustrative Mathematics 6-8 Math 2019, McGraw Hill Education Illustrative Mathematics 6-8 Math 2020, and Kendall Hunt's Illustrative Mathematics 6-8 Math 2019 draw upon this mathematics content, therefore the scores and evidence for Gateways 1 and 2 are the same in all programs, albeit with differences in navigation. There are also differences in usability as LearnZillion Illustrative Mathematics 2019, McGraw Hill Education Illustrative Mathematics 6-8 Math 2020, and Kendall Hunt's Illustrative Mathematics 2019 do not have the same delivery platform for the instructional materials.

The EdReports rubric supports a sequential review process through three gateways. These gateways reflect the importance of alignment to college and career ready standards and considers other attributes of high-quality curriculum, such as usability and design, as recommended by educators.

Materials must meet or partially meet expectations for the first set of indicators (gateway 1) to move to the other gateways. 

Gateways 1 and 2 focus on questions of alignment to the standards. Are the instructional materials aligned to the standards? Are all standards present and treated with appropriate depth and quality required to support student learning?

Gateway 3 focuses on the question of usability. Are the instructional materials user-friendly for students and educators? Materials must be well designed to facilitate student learning and enhance a teacher’s ability to differentiate and build knowledge within the classroom. 

In order to be reviewed and attain a rating for usability (Gateway 3), the instructional materials must first meet expectations for alignment (Gateways 1 and 2).

Alignment and usability ratings are assigned based on how materials score on a series of criteria and indicators with reviewers providing supporting evidence to determine and substantiate each point awarded.

For ELA and math, alignment ratings represent the degree to which materials meet expectations, partially meet expectations, or do not meet expectations for alignment to college- and career-ready standards, including that all standards are present and treated with the appropriate depth to support students in learning the skills and knowledge that they need to be ready for college and career.

For science, alignment ratings represent the degree to which materials meet expectations, partially meet expectations, or do not meet expectations for alignment to the Next Generation Science Standards, including that all standards are present and treated with the appropriate depth to support students in learning the skills and knowledge that they need to be ready for college and career.

For all content areas, usability ratings represent the degree to which materials meet expectations, partially meet expectations, or do not meet expectations for effective practices (as outlined in the evaluation tool) for use and design, teacher planning and learning, assessment, differentiated instruction, and effective technology use.
