Global Math Week: October 10 - 17, 2017
We're proud to partner with James Tanton in bringing to life a series of four wonderfully delightful learning challenges based on the Piles & Holes puzzles, a sequel to the famous Exploding Dots. The PIles & Holes Challenges are aligned to middle school standards (Grade 6).
View our guides to get started!
