Math Circles

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 Boston 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.

If you are interested in joining a Math Circle, please contact the Riverbend Community Math Center.

Fall 2018

During the fall of 2018, Riverbend Community Math Center is offering Math Circles starting the week of September 17th. We will form additional Math Circles if we have at least five students in a given age range. The groups listed below have already formed. We meet at the Beacon Resource Center at 4210 Lincoln Way West, in South Bend near the airport.

The Germain Math Circle

Typical Age: 7 to 11 years old
Time: Thursdays from 5:30 to 6:30 p.m. on the dates listed below

This semester, we are learning to figure out when a puzzle is merely difficult or actually impossible. We will learn to prove that some things are impossible. We will also play with some puzzles that no one in the world has solved yet.

Named for Sophie Germain (1776–1831)




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?
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.
