The instructional materials reviewed for eMathInstruction Common Core for High School Mathematics series partially meet expectations for Alignment to the CCSSM. The materials meet expectations for Focus and Coherence as they show strengths in: attending to the full intent of the mathematical content for all students; spending the majority of time on content widely applicable as prerequisites; engaging students in mathematics at a level of sophistication appropriate to high school; and making meaningful connections in a single course and throughout the series. The materials partially meet the expectations for Rigor and Mathematical Practices as they partially meet the expectations for Rigor and Balance and partially meet the expectations for Practice-Content Connections. Within Rigor and Balance, the materials did show strengths with providing students opportunities for developing procedural skills and balancing the three aspects of Rigor, and within Practice-Content Connections, the materials showed strength in developing seeing structure and generalizing (MPs 7 and 8).
