Math in Common is a seven-year initiative launched in spring 2013 that supports a formal network of ten diverse California school districts as they implement the Common Core State Standards in Mathematics (CCSS-M) in grades K-8. The ten unified school districts are: Dinuba, Elk Grove, Garden Grove, Long Beach, Oakland, Oceanside, Sacramento City, San Francisco, Sanger, and Santa Ana. Eight districts, all but Garden Grove and Long Beach, will continue to work together in a community of practice through June 2020. The initiative is funded by the S. D. Bechtel, Jr. Foundation. WestEd serves as the formative evaluator and California Education Partners facilitates the community of practice.
Foundation staff has partnered with all ten districts in the initiative's first five years through regular phone calls, site visits, formal grant reports, participation in three community of practice meetings each year, and involvement in optional multi-district events. Based on this experience, staff has compiled reflections on this ambitious investment in California's students and educators. We are sharing these reflections here in the belief that learning from Math in Common provides current "real-world" evidence of best practices applicable to standards implementation, as well as insights into barriers districts may encounter.
