Here is a story that isn't true: When James Tanton was a young child, he invented a machine (not true) that was nothing more than a series of boxes that could hold dots. These dots would, upon certain actions, explode. And with this machine, in this non-true story, he realized he could explain true things! In one spectacular fell swoop he explained all the arithmetic he learned in grade school (true), all the polynomial algebra he was to learn in high-school (true), elements of calculus and number theory he was to learn in high school and university (true), and begin to explore unanswered research questions intriguing mathematicians to this day (also true).

Join James to play with **Exploding Dots** together for a day and see how this astoundingly simple idea can revolutionize K-12 arithmetic and algebraic thinking and teaching. Bring an extra pair of socks with you, as this workshop will knock your first pair right off!

See what one teacher said about *Probability Play*, MoMath's previous PD session:

"This was hands-down the best PD I have attended in more than ten years as a NYC public school teacher. ... I came out of the PD with a revived enthusiasm for teaching probability." - Dave Wright
