The instructional materials reviewed for Eureka Traditional partially 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, spending the majority of time on the content from CCSSM widely applicable as prerequisites, requiring students to engage in mathematics at a level of sophistication appropriate to high school, making meaningful connections in a single course and throughout the series, 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 and fluencies, utilizing mathematical concepts and skills in engaging applications, and displaying a balance among the three aspects of rigor.
