Math Tools
Hands-on math manipulatives for K–12 classrooms, built to be used on a screen or printed for the desk. Every tool here is designed around one idea: students understand math concepts when they can see and move them, not just hear them explained.
The manipulatives are split by grade band, because a fraction circle that introduces halves in kindergarten is not the same tool as one that models operations with unlike denominators in high school. Each tool has a version for K–2, 3–5, 6–8, and 9–12, so you can find the one that matches your students without sorting through versions that are too simple or too advanced.
