Home to several leading tech companies in the world, California is known for its science and math-savviness. This is also why the state is now home to several math circles, a growing phenomenon in math education around North America. This blog tells you all about the leading math circles, aka math groups, for school students in California.

**What is a Math Circle?**

A math circle can be described as a social structure where young math enthusiasts partake in the intricacies of mathematical thinking by setting and working towards achieving mathematical goals through problem-solving and mathematical modeling. Not all circles feature competitions and formal exams; some are very informal with the learning imparted through games, stories, or hands-on activities. All of them are aimed at fostering a sense of camaraderie among math enthusiasts; they all have students who like and pursue the study of math, so the math circles offer students a social context in which to enjoy mathematics.

This form of mathematical outreach can be traced to the mathematical cultures prevalent in Eastern Europe, particularly Russia and Bulgaria. The tradition reached the US with immigrants who had received their inspiration from math circles as teenagers. These days, math circles frequently partner with other mathematical education organizations, such at the Julia Robinson Mathematics Festival and the Mandelbrot Competition.

So in effect, math circles are meetups between math experts and K-12 students or teachers where they work on problem solving and understanding mathematics as a discipline of inquiry where one conjectures and explores concepts in math with other people as opposed to just learning the established formulae. Typically, they take place outside a regular school day and the instructors are usually university professors or graduate students in math.

Below are the leading math circles in California:

• **Davis Math Circle **

The Davis Math Circle is a student-run, volunteer-based outreach program for Northern California high school and middle school students. It aims to looking beyond the standard math curriculum in schools.

*Classes/ Events/ Competitions:* The Davis Math Circle events mainly comprise of guest presentations and math lessons. This fall (2019), it had sessions by experts held over eight Saturdays (12-2 pm PST) spread across October, November and December at the Mathematical Sciences Building 2112 on the UC Davis Campus; topics covered included probability, geometry, algebra, number theory and combinatorics.

*How To Join:* These lessons are ideal for students in grades 6 to 10; the sessions are free and run on a drop-in basis. One can join by writing to ucdmathcircle@gmail.com. For more info, visit: https://davismathcircle.wordpress.com.

• **Euler Circle**

Euler Circle is a San Francisco Bay Area-based mathematics institute for advanced (high school) students. It provides a range of college-level mathematics classes and each class is the equivalent of an upper-division college mathematics class, so students tackle several problems to become familiar with new material and give a presentation after working on a paper on a topic related to the class material.

*Classes/ Events/ Competitions*: Euler Circle believes in promoting math pursuits beyond competitions. The subject is studied through advanced classes which meet for four hours a week. They are held on Tuesday and Wednesday evenings (during the period January 7 to March 11, 2020) from 6:30–8:30 pm at the Cubberley Community Center in Palo Alto. Their advanced class in winter 2020, starting in January) will be on infinite series and intermediate class will be on transitioning to proofs in combinatorics.

Meanwhile, intermediate classes meet for three hours a week. They are held on Monday evenings (during the period January 6 to March 9, 2020) from 5:30–8:30 pm, also at the Cubberley Community Center in Palo Alto. These are classes on proof techniques and mathematical writing.

*How To Join:* While official application deadline has passed, you can still apply and get in if there’s space available. You can go here to know more: https://eulercircle.com/apply/.
