Mathigon is a free mathematics learning app for web, iOS and Android. It describes itself as a mix of interactive textbook and virtual tutor. Courses are divided into small sections with problems, simulations, patterns and other interactive components. A knowledge graph is used to adapt course content, while the virtual tutor provides tailored hints and encouragement. Illustrations, narratives, real-life applications, puzzles and historical context are used in the courses. Polypad includes more than 50 virtual manipulatives, along with dynamic geometry, graph plotting and sharing. Teachers can track student progress, view saved Polypad canvases and import student rosters from Google Classroom. Mathigon also offers free webinars, tutorial videos and a library of more than 50 free student activities and teaching ideas. Most parts follow WCAG 2.1 AA, according to Mathigon, and course audio narration is available in English. Offline access and parent reporting are listed features. Use is limited to non-commercial purposes unless a commercial licensing agreement is arranged. Mathigon says it cannot promise when courses marked under construction will be finished. Its free plan is listed for students, teachers and parents.
