Welcome to the Stanford Math Circle

A math circle brings students who enjoy the beauty and fascination of mathematics together with an instructor who leads the exploration of intriguing topics. If you have any questions about our math circle don't hesitate to contact us.

Join us! We gather on Sunday afternoons from 2:00 to 4:00 in room 380-C of the math building on Stanford campus. See our schedule to view dates and speakers and follow these directions to get there. You are welcome to begin attending at any point during the school year. With a new speaker and a new topic every week or two, you don't have to worry about getting behind if you miss some of the meetings.


  • Mission: Our goal is to have a great time learning about great math. We aim to provide a resource for students in the San Francisco Bay area who enjoy exploring mathematics.

  • Content: One math circle can't appeal to students of all ages, so the Stanford circle has focused on the interests of high school students. Anyone is welcome to attend, however, including parents. Some advanced middle school students might also find the meetings interesting. Talks have covered number theory, advanced counting techniques, Euclidean geometry, problem solving strategies and more.

  • Tuition: There is no charge for attending the Stanford Math Circle. However you can support us with your tax deductable contributions which we use primarily to provide small honorariums for the speakers. A financial statement is available for all past sessions.

  • Joining: Joining is easy. All you have to do is come to our meetings. The only admission requirement is an interest in mathematics!
