About us

At the San Francisco Math Circle, we make math accessible, inclusive, and fun!

The SF Math Circle is an extracurricular math enrichment program affiliated with the Center for Science and Math Education at San Francisco State University. SF Math Circle supports students from diverse backgrounds in developing their identities as capable, confident problem solvers.

In our after-school classes and camps, we provide a supportive, collaborative, and fun environment where students explore engaging, hands-on puzzles and games that involve both creativity and critical thinking.

Students explore these puzzles and games in small groups where they have the opportunity to collaborate with their peers and to receive personalized attention and support from SF Math Circle facilitators.

Please note that our focus is primarily on helping students to engage in creative mathematical exploration and problem-solving rather than building their skills in arithmetic or other traditional K-12 math.
