Joshua Zucker, "Exploding Dots"

In this series of videos, Joshua Zucker (Julia Robinson Math Festivals) leads a Math Teachers' Circle session titled "Exploding Dots." Josh introduces an imaginary counting machine that explodes teachers' preconceptions about arithmetic.

Math Teachers' Circles (http://www.mathteacherscircle.org) are professional communities of middle school math teachers and mathematicians who meet regularly to work on rich math problems. Our goal is to help middle school math teachers confidently incorporate open-ended, authentic mathematical problem solving in their teaching.

This video was filmed in summer 2014, when 30 mathematicians and math teachers from across the country came to a "How to Run a Math Teachers' Circle" workshop at the American Institute of Mathematics in Palo Alto, CA.
