The Calvin University 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. If you have questions about whether Math Circle may be right for your student, please call or send email!

The Calvin University Math Circle was formed in Fall 2017 and is supported by the Department of Mathematics and Statistics, the Office of the Provost, and the Office of Pre-College Programs.

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).
