Math in Common® (MiC), established in 2013 with significant support from the S.D. Bechtel, Jr. Foundation, is a collaboration of diverse California school districts working together to learn from and support one another in the transition to the Common Core State Standards for Math (CCSS-M) in grades K-8. MiC uses a Continuous Improvement framework to build internal capacity in districts by analyzing their system, determining root causes of problems, and testing researched based change ideas to close inequitable gaps in student outcomes.
