COVID-19 Update: Math Circles will begin online this semester and will
remain online until the 7-day average count of new cases in St. Joseph
County drops below 50 cases per day or a vaccine for children is
available.

Math Circles are for students with long attention spans who enjoy engaging in mathematical conversation. Students will learn to collaborate with others while developing and defending their mathematical ideas. Our pedagogy is based on the approach used in the Global Math Circle.

Math Circles are programs for students who love math and want a challenge. Students should have long attention spans and should be eager to have a discussion about mathematical ideas with like-minded peers.

This semester, faculty and studebts from Notre Dame are working with Riverbend Community Math Center to offer Math Circles for five different age ranges, plus an online research group for middle and high school students. All Math Circles will start the last week of September.

Typical Ages: 4--5 years old

Time: Thursdays from 5 to 6 p.m. on the dates listed below

Named for Joan Birman (1927–)

Typical Ages: 1st -- 2nd grade students

Time: Wednesdays from 5 to 6 p.m. on the dates listed below

Named for Evariste Galois (1811–1832)

Typical Ages: 3rd -- 5th grade students

Time: Thursdays from 5 to 6 p.m. on the dates listed below

Named for Sophie Germain (1776–1831)

Typical Ages: 6th -- 8th grade students

Time: Thursdays from 5 to 6 p.m. on the dates listed below

Named for Andrew Wiles (1953–)

Typical Ages: high school students

Time: To Be Determined

Named for Leonhard Euler (1707–1783)

The research group always meets online, and is designed for older students who want to take a deep dive into a single topic, learn the LaTeX language in which most math papers and books are published, and improve their mathematical writing skills. Exceptional amounts of focus, determination, and patience are required, and we assume that participants are familiar with the content of Algebra 1.

Typical Ages: middle and high school students

Time: Wednesdays from 8 to 9:30 p.m.

- Exploding and Collapsing Boxes
- We have heard of base ten, base two, and base sixteen, but is it possible to make sense of base three halves?
- Three-sided Cylindrical Dice
- How can we construct a fair three-sided cylindrical die?
- For example, a "short" cylinder will almost always land on one of the ends and rarely on the side. A tall cylinder will almost always land on its side and rarely on an end. How should we construct the die so that if we label the ends with "1" and "2" and the side with "3" each number will have an equal chance of coming up?
- Emptying the Atlantic Ocean with a Thimble
- How many thimbles of water would it take to empty the Atlantic Ocean?
- Extension of James Tanton's Intersection Math Problem
- We extended James Tanton's Intersection Math Problem counting the intersections of a bipartite graph to a tripartite graph.
