Math in Common® (MiC) is an initiative that supports a network of 10 California school districts as they implement the Common Core State Standards in Mathematics (CCSS-M) across grades K–8.

This report explores how four MiC school districts are designing and implementing site-based, lesson-focused teacher professional learning in the Common Core era.
