Membership in the California Mathematics Council entitles you to our nationally renowned quarterly journal, the ComMuniCator, advance notice of our conferences, occasional documents published by one of our committees, and involvement in the decisions of the council. It also helps us give you a voice with those who effect public and private education in California, the United States, and the world. California members are automatically assigned a Section Membership based on their mailing address.

Please join your 10,000 fellow educators and parents from California, 45 other states, Canada, Australia, and 7 other foreign countries in making all this possible.
