What is Mathigon?
Mathigon calls itself the mathematical playground. Its courses read like an interactive textbook: each chapter is split into small steps, and you solve a problem, drag a shape or run a simulation before the next part appears. A virtual tutor called Archie gives hints when you get stuck.
Courses cover geometry, numbers and algebra, and probability, with topics such as fractals, graph theory, circles and pi, and prime numbers. There are also activities such as a timeline of mathematics, the Factris game, multiplication flash cards and a set of puzzles. Mathigon is part of Amplify, and its Polypad manipulatives have moved to Amplify's own site.
