By request from different districts we have worked with nationally, we have developed a Standards Alignment Guide for each of three different sets of state standards: the Arizona Mathematics Standards, the California Common Core State Standards for Mathematics, and the Common Core State Standards for Mathematics. The alignment guides are meant to help educators determine which MPP lessons align with and complement their district-approved curricula. Purchase of a 2nd edition MPP book includes access to an Online Digital Resource Library which includes all three of these Standards Alignment Guides.
