Thanks to Math for America for supporting our Math Teacher Circle with a $2000 seed grant!


In July 2012 four of us attended a workshop hosted by AIM on organizing and facilitating Math Circles. Not that we're experts now, but we got lots of good ideas. Here we are in front of the MAA's wonderful conference facility in Washington DC.
