The PCMI 2001 Summer Session had three strands:

1. The Euclidean algorithm and its applications to algebra and the theory of numbers.
   Focused exclusively on learning mathematics by working problems together, this course explored the fundamental algorithm on which much of arithmetic and algebra is based.
   
   
2. Math in the classroom - reflections on practice
   The participants actively investigated, considered, and discussed examples illustrating concepts and connections in school mathematics and reflected on how such ideas can shape classroom teaching.
   
   
3. Working Groups
