Math K-8 Summary of Alignment & Usability

Investigations Grades K-2 does not meet the expectations for Alignment to the Common Core State Standards and Usability. While numerous units of material are provided, they do not spend the majority of instructional time on major work of the grades. The sequence in which topics are covered is not consistent with the logical structure as outlined by the CCSSM and address topics before the grade level introduced in the standards. Therefore, materials are lacking important connections between standards, clusters and/or domains where appropriate and required. Overall, the instructional materials included in this series lack mathematical focus and coherence.
