Discovering Mathematics: Algebra, Geometry, Advanced Algebra

The instructional materials for the Discovering series meet expectations for alignment to the CCSSM for high school. For focus and coherence, the series showed strengths in the following areas: attending to the full intent of the mathematical content contained in the standards, attending to the mathematical modeling process, spending the majority of time on the content from CCSSM widely applicable as prerequisites (WAPs), engaging students at a level of sophistication appropriate to high school, and explicitly identifying and building on knowledge from Grades 6-8 to the high school standards. For rigor and the mathematical practices, the series showed strengths in the following areas: supporting the intentional development of students' conceptual understanding, opportunities for students to develop procedural skills, utilizing mathematical concepts and skills in engaging applications, displaying a balance among the three aspects of rigor, supporting the intentional development of reasoning and explaining, and supporting the intentional development of seeing structure and generalizing.
