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.

Faculty and students from Notre Dame partner with Riverbend Community Math Center to offer Math Circles for four different age ranges. All Math Circles will meet on Wednesdays from 5 to 6 p.m. in Pasquerilla Hall at Notre Dame from September 14th through December 7th. We will not meet October 19th due to Notre Dame fall break or November 23rd due to Thanksgiving break.

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

- Smarties Sandwiches
- What is the probability of getting a "sandwichable" roll of Smarties candies?
- 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.
