The California Mathematics Council (CMC) is a statewide organization, comprised of 6,000 teachers, administrators, parents, and teacher-educators from California, 45 other states, Canada, Australia, and seven other foreign countries, who are committed to improving mathematics learning in the private and public classrooms throughout California, North America and the world.

Since COVID, JRMF has been able to transition into a digital organization. The curated library of our favorite activities is provided free of charge on our website and includes sequenced activity slides in English and Spanish as well as digital apps. Every week, we host interactive webinars in English and Spanish during which trained facilitators guide students through a new or updated activity. We have also started to offer webinars-on-request so that we can support private groups and communities in their mathematical explorations.
