About: The SFMC Elementary Math Circle is an alternative math enrichment program designed to develop a positive attitude towards mathematics by introducing young children to elements of mathematical culture.  We carefully select and train mathematicians who have the capacity to gracefully and compassionately share their enthusiasm for mathematics with children.  Our instructors lead engaging mathematical activities on topics chosen from higher mathematics including number theory, game theory, combinatorics, probability and statistics, abstract algebra and topology.  To learn more, please view our video.

Welcome New and Returning Students!

The SF Math Circle at Clarendon welcomes new* and returning students to our program!  The SF Math Circle at Clarendon is designed to be a safe and enjoyable place for students who like to solve problems and do mathematics.  We provide rich mathematical content in an engaging context, as well as much encouragement, but the students must bring the rest -- energy, interest, and an openness to try new things!  While students don't have to identify as loving math from the onset, they should at least have an open mind about trying out the SF Math Circle and should demonstrate enthusiasm for the program within the first two weeks.  In order to help your students get a sense of whether they would like our program, please show them our SF Math Circle video.  Additionally, we encourage parents/guardians to review our Elementary Parent Handbook to get a sense of our policies and to determine if we are a good fit for your family.

*Please note: The SFMC Elementary Math Circle program at Clarendon gives priority enrollment to students attending Clarendon Alternative Elementary School.

Spring 2018 Program Details

Class Levels

The SFMC Elementary Math Circle program at Clarendon gives priority enrollment to students attending Clarendon Alternative Elementary School.  We have one math circle for 2nd-3rd graders and one math circle for 4th-5th graders.  The mathematical content is very different from traditional K-12 math and is equally new and stimulating for all students.


The SFMC Elementary Math Circle program at Clarendon meets on Mondays from 3:30-4:30pm.  The program will run 9 weeks, starting in March and ending in May.  Please note that all dates and times are tentative and subject to change.

  • Mondays*:  3/12, 3/19, 4/2, 4/9, 4/16, 4/23, 4/30, 5/7, 5/14 (no Math Circle on 3/26)
  • Time: 3:30-4:30pm
  • *All dates and times are tentative and subject to change


SFMC Elementary is a fee-based program.  The cost is $270 per student per semester; this includes 9 weeks of instruction.  Additionally, we have a generous sliding scale to ensure that all families who are interested in Math Circle can afford to attend.


Due to the high demand for our program and a desire to be fair and equitable to all families who wish to participate, we now use a lottery system to distribute the remaining available seats to interested students at Clarendon. Enter your student for the Lottery via the ActivityHero widget below.

Students will be randomly selected from the pool of all Lottery entrants. Those who are selected will be contacted via email and offered a spot in the SF Math Circle at Clarendon. Parents/Guardians must respond within 3 school/business days to claim their student's spot. The number of students selected in the Lottery will be equal to the number of seats available in each session.

Entrants with duplicate registrations may be removed from the Lottery drawing without notice. Entrants with incomplete registration forms may also be removed from the drawing. 

Thanks for your patience and understanding as we continue to evolve to meet the needs of our various sites and communities.

Returning Students: Priority Registration is offered to returning students from the previous semester. Space is limited and enrollment is determined on a first come, first served basis. We encourage you to sign up early!
