The Fall 2021 program is for 4th and 5th grade students, nominated by Charlottesville area schools.

The focus of the Math Circle is on learning mathematics through interactive exploration and solving challenging, non-standard problems. The goal is not to increase proficiency in routine curriculum skills, but rather to expose students to ideas and concepts in Math that encourage them to think creatively and generate interest in mathematics. Students learn topics and practice solving problems in diverse areas of Mathematics, including geometry, combinatorics, logic, and number theory. Meetings involve working in groups, as well as Math games where students work in teams on fun, challenging problems. The meetings in Fall 2021 are led by professors Slava Krushkal and Juraj Foldes, with the assistance of Kristina Cernekova, Rostislav Akhmechet and Lousa Liles, all members of the UVa Math deparment.
