The Calvin College Math Circle is an opportunity for 6th–8th grade students (typically 11–13 years old) to engage with exciting problems and topics in mathematics. Meetings are led by a professor in the Calvin math department and typically begin with a warmup activity or game that leads into the day's problem or topic. The Math Circle seeks to generate enthusiasm for problem-solving in mathematics. Students also discover applications of mathematics and participate in a community that nurtures critical thinking, communication, and abstraction.
Time & Location
We meet at Calvin College in North Hall 276 on Monday afternoons. For Fall 2018 we will meet from September 24 through November 12 (eight sessions). Parking is available in Lot 5 (west of the engineering building) and Lot 6 (west of the aquatic center).
- 3:45–4:00 p.m.: setup and arrival
- 4:00–5:15 p.m.: main activity
- 5:15pm: dismissal
Cost & Application
- (update July 24, 2018) Math Circle starts again in September! We will meet again on Monday afternoons. We hope students from last year participate again this year, but we expect there will be new students, too. So we will have all new topics that don’t necessarily build on topics from last year.
- Tuition is $80 per semester
- Registration is via Eventbrite (space limited to 20 students)
- At the first meeting please bring a signed copy of the consent form

The Math Circle is an enrichment activity that explores topics generally outside the regular mathematics curriculum. It is for 6th-8th grade students (typically 11-13 years old) who are interested in problem-solving and applications.
Math Circles originated in Russia in the 1930s, appeared in the United States in the 1990s, and are promoted by the National Association of Math Circles. Nearby circles include the Michigan Math Circle (Ann Arbor, MI) and the Maize & Blue Math Circle (Dearborn, MI).
