Introducing Abelian Groups using Bullseyes and Jenga
Michael D. Smith · PRIMUS · 2015
The purpose of this article is to share a new approach for introducing students to the definition and standard examples of Abelian groups. The definition of an Abelian group is revised to include six axioms. A bullseye provides a way to visualize elementary examples and non-examples of Abelian groups. An activity based on the game of Jenga is used to help students determine for themselves the sets and operations that combine to form Abelian groups. A second collection of more advanced examples and non-examples of Abelian groups is also represented on a bullseye. This article is intended for those who teach undergraduate abstract algebra.
