Riverbend Math Circles at Notre Dame
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.

Content From Past Math Circles
- 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? * November 15, 22 * December 6, 13 * November 15, 22 * December 6, 13
- 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.
