My wife and I live in San Francisco and love our city. When home I get out to Golden Gate Park once or twice a week to play disc golf. We love hosting parties. Our recent parties have included backgammon parties, chocolate parties, bacon parties, and of course birthday parties for friends and family. I have a ball as a "mathemagician" to 5th graders once a week. We vacation at least once a year in Hawaii. Our favorites include Wailea on Maui and Hanalei on Kauai. I am the author of Discovering Geometry, Patty Paper Geometry, The Mathercise series, What's Wrong With This Picture?, Smart Moves, and my latest and current favorite, Pirate Math. Let's talk about all things Geometry.
