The Common Core State Standards for Mathematics (CCSS-M) set rigorous standards for each of grades 6, 7 and 8. Strategic Education Research Partnership (SERP) has been working with two school districts, Oakland Unified School District and San Francisco Unified School District, to evaluate extant policies and practices and formulate new policies based on the CCSS-M shifts that promise to work better for students. This work has culminated in school board adoptions of new policies in both districts. This report focuses on the problems, solutions and designs that that have been found in the CCSS-M and can be of immediate use to other districts and states.
