Math Student Circles (MSCs) are groups of students who meet regularly with mathematics professionals to engage in problem solving. Since their beginnings as primarily competition-focused programs, MSCs in the U.S. have grown into a popular form of mathematics enrichment for students at all grade levels. Many are run as after-school programs serving students from socioeconomically disadvantaged schools (

Long, Pantano, White, & Wiegers, 2017).

Pedagogically, MSC facilitators should foster an enjoyment of mathematical thinking through creating a highly engaging, collaborative, supportive Math Circle culture that supports participation by all. Problems should be low floor, high ceiling, and should promote deep conceptual thinking and the development of mathematical habits of mind. The SF Math Circle has a wonderful description of their pedagogical approach. Organizers should also check out our MSC Toolkit for additional tips.
