This article reports the encounters of a mathematician educator with a mathematics journal paper over a few years. The paper trail illustrates an equal fascination with mathematics and its power to educate.

This article focuses on a challenging geometry problem that was originally posed to primary school students. Four solution approaches, ranging from elementary to advanced, are discussed. Reflections on these approaches and the problem solving processes are also shared.

In this paper we describe a problem solving course for first year undergraduate mathematics students who would be future school teachers.
