The mathematical playground: free interactive courses and manipulatives
Mathigon is a free, award-winning interactive mathematics learning platform that reimagines the textbook with step-by-step, conversational courses, virtual manipulatives, and visual exploration. Now part of Amplify, it offers educators and students dozens of self-paced courses, classroom activities, and the Polypad manipulatives canvas to make math more engaging and hands-on.
Step-by-step, narrative-driven math courses that adapt to the learner and reveal content as students respond, covering geometry, algebra, probability, and more.
A digital canvas of virtual manipulatives (number tiles, fraction bars, geometry tools, dice, and more) for problem-solving, pattern exploration, and collaboration. Now hosted by Amplify.
Ready-to-use interactive activities and lesson plans teachers can assign or project for whole-class exploration.
A growing library of self-paced 'textbook of the future' courses spanning middle school, high school, and recreational mathematics topics.
Rich animations, diagrams, and visualizations that make abstract mathematical concepts intuitive and concrete.
Free content available in more than 20 languages, broadening access for students and teachers worldwide.
Teachers use Polypad and interactive courses to demonstrate concepts visually and run hands-on, exploratory lessons.
Students work through narrative, interactive courses at their own pace to build intuition for geometry, algebra, and probability.
Parents use the free courses and manipulatives to supplement or lead math learning at home.
Curious learners explore recreational math, patterns, and visual proofs through Mathigon's activities and playground tools.
Shared Polypad canvases let students and teachers work together in real time on mathematical investigations.
