Watch this space or sign up for our mailing list: we will announce our 201819 meeting schedule sometime this summer!
The San Diego Math Teachers’ Circle is an informal monthly program that aims to engage teachers and mathematicians in working together on intriguing and stimulating problems. Through this collaborative process, we seek to provide teachers with an opportunity to enrich their knowledge and appreciation of mathematics. We feel that problemsolving abilities and critical thinking engender success in many fields, and that promoting these abilities in teachers will, in turn, foster them in their students.
The San Diego Math Teachers' Circle is free to all middle school math teachers in San Diego County. We meet once a month on Saturdays from October to April (click here for a detailed schedule). A light continental breakfast is provided at every meeting!
The San Diego Math Teachers’ Circle is not affiliated with any school or school district and is open to teachers from public schools, private schools, or home schools. It is a program similar to the San Diego Math Circle, but geared primarily for middle school teachers. Activities will be led by math professionals from the Art of Problem Solving, our staff, and others.

About our Logo
Our logo reflects both our coastal location and the mathematical nature of what we do. Reminiscent of a nautilus shell against an ocean background, the spiral was generated by dividing a disc into 12 equal parts and dropping perpendiculars from one ray to the adjacent one. This process creates seashelllike shape that is not only aesthetically pleasing, but also gives rise to a number of interesting math questions spanning a broad range of depth and difficulty. What type of triangles form the seashell shape? How are they related to one another? What is the length ratio of two adjacent triangles of the same color? Suppose we start at the 2 o’clock position and continue spiraling inward ad infinitum. What is the limit of the sum of the short lengths of all the triangles? For answers to some of these questions and more, click here.
