The instructional materials reviewed for Math Expressions Grade 6 partially meet expectations for alignment to the CCSSM. The instructional materials meet expectations for Gateway 1, focus and coherence, by focusing on the major work of the grade and being coherent and consistent with the Standards. The instructional materials partially meet expectations for Gateway 2, rigor and balance and practice-content connections, by reflecting the balances in the Standards and helping students meet the Standards’ rigorous expectations by giving appropriate attention to the three aspects of rigor, and the materials partially connect the Standards for Mathematical Content and the Standards for Mathematical Practice (MPs). Since the instructional materials partially meet expectations for alignment, they were not reviewed for usability in Gateway 3.
