In October 2010, accompanied by doctoral candidate Marth Byrne, I returned to Obafemi Awolowo University in Ile-Ife, Nigeria.  Our visit was supported by the NSF and the International Mathematical Union, and of course OAU.  The goal of this visit was to share the joy of mathematical discovery with our many Nigerian friends.  As with Math Teachers' Circle, we focused on engaging the students with active, hands-on learning. - Michael Nakamaye
