What it does

Interactive maths tools, courses and manipulatives, including a route to Polypad.

Mathigon encourages exploration with tools for patterns, geometry, sequences and other mathematical ideas. Polypad provides a manipulative-based route, while individual activities invite investigation. Choose a question before opening a tool, then change one element and describe what happens. Teacher resources and lesson plans can help turn open exploration into a classroom task.
