In this perspective-expanding and enjoyable talk, Dan Finkel invites us to approach learning and teaching math with courage, curiosity, and a sense of play. Dan Finkel wants everyone to have fun with math. After completing his Ph.D. in algebraic geometry at the University of Washington, he decided that teaching math was the most important contribution he could make to the world. He has devoted much of his life to understanding and teaching the motivation, history, aesthetics, and deep structure of mathematics. Dan is the Founder and Director of Operations of Math for Love, a Seattle-based organization devoted to transforming how math is taught and learned. A teacher of teachers and students, Dan works with schools, develops curriculum, leads teacher workshops, and gives talks on mathematics and education throughout the Pacific Northwest and beyond. Dan is one of the creators of Prime Climb, the beautiful, colorful, mathematical board game. He contributes regularly to the New York Times Numberplay blog and hosts Seattle’s Julia Robinson Math Festival annually. In his spare time he performs improv comedy in Seattle. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
