Los Angeles Math Circle

Welcome to the Math Circle

The Spring 2013 session starts on April 7th.

Los Angeles Math Circle (LAMC) is a top-tier math circle open to elementary, middle and high school students interested in mathematics and eager to learn. LAMC is a program of the Department of Mathematics at UCLA and is supported by the National Science Foundation, the Boeing Employees Community Fund, Raytheon, a gift from the Glickman family, and math circle families donations. 

Following the traditions of Russian and Eastern European math circles, the program focuses on showcasing the beauty of mathematics and its applications, improving problem solving skills, preparing students for a variety of contests and competitions, creating a social context for mathematically inclined students as well as attracting students to math-related careers.

Types of meetings:

  • problem-solving sessions (most of the meetings);
  • expository talks on various topics;
  • preparation for the American Mathematical Competitions (AMC8, AMC10, AMC12, AIME, USAMO);

The topics we cover are as varied as advanced plane geometry, elementary number theory, fractals, combinatorics, game theory for the older students, logic, counting techniques, basic combinatorics for the younger ones. The main goal is to learn wonderful mathematics not covered in a typical school curriculum but accessible to the mathematically inclined students. Another goal is to actively engage students in problem solving and to learn effective problem solving strategies. To get an idea of what we are doing, please look at the titles and descriptions of past meetings which are available on our "Circle calendar" for the current year and on our "Archive" page for previous years.

Math Circle Structure

In 2012-2013, Math Circle will have the following levels of participation:

  • Early Elementary Circle  (grades 2-3; room MS 3915H, 1 hr),  led by  Melinda Speckman;
  • Junior Circle (grade 4; room MS 3915A), led  by Dr. Oleg Gleizer;
  • Beginners Circle (grade 5-6; room TBA), led by Jeff Hicks;
  • Intermediate Circle  (grades 6-7; room TBA), led by Jeff Lewis;
  • Advanced Circle (grades 7-8; MS 6201), led by John Lensmire;
  • High School  Circle (grades 8-12; MS 6221), led by Mike Hall and Yingkun Li;

All Math Circle meetings take place on Sunday afternoons at UCLA.

Enrollment for Fall 2012

Please apply for Fall 2012 by going to "Apply to LAMC" on the left toolbar. Please submit your complete application before August 20th. We expect that the number of applicants will greatly exceed the number of spots we have in the math circle. Please be sure to answer all the questions in the application. While given some priority, previously enrolled students do not automatically get a spot in the math circle and need to go through the same application process. 

Important Note: Math. Sci. Building Access

Starting in early April 2011, the Mathematical Science Building will be locked on Sundays. The glass doors on the 5th floor (entry from the breezeway with vending machines) should be unlocked during the times of the math circle. However, all other doors in the building will be locked. If you are accustomed to entering the building through other doors, please make sure that you know how to enter through the doors on the 5th floor. Please see our Directions Page for more information.

Please refer to FAQs if you have questions about the proper placement (choice of group) and other questions related to math circle.

Please see our Directions page for details on how to get there.

Contact LAMC

If you have any questions or comments, please write to Dr. Olga Radko, director of the Los Angeles Math Circle, at radko@math.ucla.edu after consulting the FAQs.

If you would like to provide anonymous feedback on the circle please use "Contact us" form on the left toolbar. Keep in mind that if you want to receive an answer to your comments you need to provide a return address.

Coming up next weekend:

04/07 -- Advanced Circle: Geometry Refresher

This week we will review some geometry concepts in preparation for the coming weeks.

4/7 -- Beginners Circle: Relays!

04/07 -- High School Circle: Pick's Theorem and Earhart Theory (Mo Omar)

This week we will have a guest speaker from Caltech to discuss Pick's theorem and generalizations.

04/07 -- Intermediate Circle: Math Relays!

We will be starting off the quarter with Math Relays!

04/07 -- Junior Circle: Three solutions to one problem. (Oleg Gleizer)

At the end of the previous quarter, we considered the following problem. Prove that medians of any triangle in the Euclidean plane intersect at one point and that the intersection point divides them in the ratio 2:1 counting from the corresponding vertex. We are going to give three different proofs to the theorem, each coming from a distinct, and very important, branch of mathematics. In the process, we will learn a bit of geometry of masses and barycentric coordinates, linear algebra, and classical (Greek-style) geometry of the Euclidean plane.
