About Thinking Math
Thinking Math is a collection of visual, hands-on activities designed to build genuine mathematical thinking. Each activity uses a concrete puzzle to introduce abstract mathematical ideas — relations, symmetry, combinatorics, spatial reasoning — so the insight emerges through the solving process rather than being taught first.
Who it's for: centered on late elementary through high school, but accessible to anyone willing to think with their hands.
Created by Bill Rishel, drawing on 20 years of developing innovative math activities.
