Students examined positive and negative numbers in real world contexts and related the meaning of the distance from the number to zero. Students began exploration into the concept of the opposite of the opposite of a number as being the number itself. In Grade 6, students performed operations with decimals and fractions by following an algorithm or utilizing a number line. Students recognized that opposite signs in rational numbers indicated locations on opposite sides of zero on the number line. In Grade 8, students will continue to use operations with positive and negative integers and rational numbers to solve equations by using inverse relationships and operation rules. In Grade 8, students will use operations with positive and negative integers and rational numbers to find solutions for a system of linear equations using algebraic methods. In Grade 8, students will begin to examine the use of square and cube roots and will discover that square roots of negative numbers cannot be found in the real number system.”

In Topic 6, they used what they learned about ratios to work with a special type of ratio called a percent. In Topic 5, students learned about a special type of ratio called a rate. In Grade 8, students will understand the connections among proportional relationships, lines, and linear equations. Students will also graph proportional relationships and compare proportional relationships represented in different ways. In Grade 8, students will use similar triangles to investigate slope, and they will derive the equations y = mx and y = mx + b for lines.”
- Topic 5 Overview, Solve Problems Using Equations, Math Background, Coherence, “In Grade 6, students learned to evaluate expressions, and then applied this knowledge to write and solve one-step equations and inequalities. Students represented and analyzed the quantitative relationship between dependent and independent variables and established an understanding that a change to one quantity directly affects the other. In Grade 6, students learned to use graphs, tables, and number lines. They analyzed solutions and related mathematical models to expressions, equations, and inequalities. In Grade 8, students will extend their understanding of expressions, equations, and inequalities to more complex versions. They begin to explore equations that contain two variables. In Grade 8, students continue to make connections between models and equations including proportional relationships, lines, and linear equations.”

The instructional materials reviewed for enVision Mathematics Common Core Grade 7 meet expectations that the underlying design of the materials distinguishes between problems and exercises. In essence, the difference is that in solving problems, students learn new mathematics, whereas, in working exercises, students apply what they have already learned to build mastery. Each problem or exercise has a purpose.
Materials engage students in both problems and exercises through the grade level. Problems where students learn new mathematics are typically found in the Lesson’s Visual Learning Bridge. This portion of the lessons consists of visual examples that formalize the mathematics of the lesson by providing guided instruction of the math concepts with one example stepped-out. Examples from the Teacher Resource include:
- Lesson 2-5, Graph Proportional Relationships, Visual Learning, Example 1, students learn how to recognize a proportional relationship using graphs, “Tanya exercise for 30 minutes. She noted the Calories burned at three times during her workout. How can Tanya use this information to find how many Calories she burned after 15 minutes of exercise?”
- Lesson 4-4, Expand Expressions, Visual Learning, Example 3, students learn two methods for expanding complex expressions, “Simplify the expression -$$\frac{1}{3}$$ (2 - 3x + 3). One way: Use the Distributive Property first to distribute the coefficient -$$\frac{1}{3}$$. Another way: Simplify within the parentheses first. Then distribute the coefficient -$$\frac{1}{3}$$.”
- Lesson 8-4, Solve Problems Using Angle Relationships, Visual Learning, Example 1, students learn to solve problems involving adjacent and vertical angles, “A skewed intersection has two roads that intersect at more than 20 degrees away from 90°. Determine whether the road intersection shown is skewed by finding the measures of ∠ABC and ∠DBE.”
Exercises, where students apply learning to build mastery, are typically found in the Practice and Problem Solving section. These exercises build independent proficiency, challenge higher-order thinking, and simulate high-stakes testing questions. Examples from the Teacher Resource include:
- Lesson 1-3, Add Integers, Practice & Problem Solving, Item 18, students add two negative integers to find a solution, “A deep-sea diver dives 81 feet from the surface. He then dives 14 more feet. The diver’s depth can be represented by -81 + (-14). What is the diver’s present location?”

Why?’”
- Lesson 4-2, Generate Equivalent Expressions Explore It!, ETP: During, “3. Observe Student Work: How do students represent the total number of eggs with a diagram? Students might draw a diagram that indicates an unknown number of cartons with 6 eggs each and unknown number of cartons with 12 eggs each. How do students represent the total number of eggs using an expression? Students might let x represent the number of cartons with a half-dozen eggs and y represent the number of cartons with a dozen eggs and write the expression 6x + 12y. If needed, ask, What is known about the situation? What is unknown?”
- Lesson 7-4, Use Probability Models, Explain It!, ETP: After, “4. Discuss Solution Strategies and Key Ideas: Have students present their analyses of the models. Encourage them to use mathematical terms, such as outcome, chance, and probability. Have students discuss if all the team members have the same probability of being chosen caption (they do). Then have them discuss if the probability would be the same or different if their caption was not drawn randomly; if the name is not drawn randomly, each team member would not have the same chance of being picked. 5. Consider Instructional Implications: When presenting Example 1, make connections between the random drawing of a name in the Explain It, and the random drawing of marbles. In the Explain It, each team member had only one instance of their name in the draw, so each probability was equal. In Example 1, however, there are multiple marbles of each color. Have students discuss how the chess team draw could be altered to have uneven outcomes for team members; for example, some team members may be able to enter a name more than once.”

The Topic Opener also contains Advanced Concepts for the Teacher that provides examples and adult-level explanations of more advanced mathematical concepts related to the topic with explanations and examples to support teacher understanding of the underlying mathematical progressions. Examples from the Teacher Resource include:
- Topic 2, Analyze and Use Proportional Relationships, Math Background, “Solving Proportions by Inspection: Equivalent ratios are ratios that express the same relationship between numbers. When two equivalent ratios have the same first or second term, then the other terms are equal. For example, if $$\frac{z}{x}$$ is equivalent to $$\frac{z}{y}$$, then x must equal y. For some equivalent ratios, one term is a multiple of a corresponding term of the other ratio. For example, the ratio $$\frac{2}{5}$$ shows a relationship of 2 to 5, shown in the diagram as 2 green for every 5 blue. The ratio $$\frac{4}{10}$$ shows a relationship that is equivalent to 2 groups of 2 and 5 groups of 2. Therefore the ratio $$\frac{4}{10}$$ is equivalent to $$\frac{2}{5}$$. Any ratio in the form of $$\frac{2n}{5n}$$, where n $$\not=$$ 0 is equivalent to $$\frac{2}{5}$$. This is generalized as a proportion, $$\frac{a}{b}$$ = $$\frac{an}{bn}$$.” Visual representations are provided.
- Topic 4, Generate Equivalent Expressions, Math Background, “Equivalence of Algebraic Expressions: Two expressions are equivalent if, for any value in the domain of the expression, the expressions represent the same value. Expressions that are not equivalent for all rational numbers may be equivalent on more restricted domains. For example, consider a single-element domain of (1). The following expressions are equivalent on the domain. Restricted domains can also be infinite. For all positive rational numbers, the expressions x and |x| have equal values. Therefore on the domain of x $$\ge$$ 0 the expressions x and |x| are equivalent. These same expressions are not equivalent on a domain of all rational numbers. Disproving equivalence over a domain requires only a single counterexample. Proving equivalence over infinite domains cannot be done by example. The properties of real numbers and the properties for simplifying algebraic expressions are given as a set of rules that always produce or verify equivalent expression for the set of all rational numbers.” Visual representations also provided.

The instructional materials reviewed for enVision Mathematics Common Core Grade 7 contain explanations of the instructional approaches of the program and identification of the research-based strategies.
EnVision is based on research-based strategies. According to the Teacher Resource Program Overview, “enVision Mathematics embraces time-proven research principles for teaching mathematics with understanding. One understands an idea in mathematics when one can connect that idea to previously learned ideas (Hiebert et al., 1997). So, understanding is based on making connections, and enVision Mathematics was developed on this principle.” Additionally, the core instructional model is based in research, “Over the past twenty years, there have been numerous research studies measuring the effectiveness of problem-based learning, a key part of the core instructional approach used in enVision Mathematics. These studies have found that students taught partly or fully through problem-based learning showed greater gains in learning. However, the interaction of problem-based learning, which fosters informal mathematical learning, and more explicit visual instruction that formalizes mathematical concepts with visual representations leads to the greatest gains for students. The enVision Mathematics instructional model is built on the interaction between these two instructional approaches.”
