The Chico Mathematics Project is one of 19 sites statewide of the California Mathematics Project. The California Mathematics Project is under the umbrella of the California Subject Matter Projects. The focus of all of these professional development programs is to provide a rich environment for teachers to increase their understanding of the subject matter that they teach and to enhance their instructional strategies to improve student learning.

The Chico Mathematics Project offers a variety of programs for both teachers and students in the Northstate. The project serves a large geographic area, including Butte, Colusa, Glenn, Lake, Lassen, Modoc, Nevada, Plumas, Shasta, Sierra, Siskiyou, Sutter, Tehama, Trinity and Yuba Counties. The many projects of the Chico Math Project all try to incorporate a supportive atmosphere to address current mathematics education issues involved in becoming better mathematics teachers. Most programs for teachers are residential in nature and combine summer institutes with academic year follow-up activities. Programs for students are generally one day events at the California State Univerity, Chico campus.
