Mathigon contains courses, activities and resources for the entire mathematics curriculum, all of which are completely free to use. We've made our content as flexible and accessible as possible – no matter how you like to teach, or which technology you and your students have access to.
Our highly interactive courses are aligned to national standards like the US Common Core. Students can explore them as a homework assignment, in a “flipped classroom”, or when learning remotely.
Polypad is a library of virtual manipulatives: from polygons and fraction bars, to algebra tiles and random dice. Teachers and students can share links to their saved canvases. Explore…
On our teacher dashboard, you can track your students’ progress in real time and see all their saved Polypad canvases. You can also import student rosters directly from Google Classroom. Learn more…
Here you can discover games like Factris, Origami folding instructions, multiplication flash cards, a customisable treasure hunt, a timeline, puzzle calendars, and so much more. Explore…
Keep scrolling for many different lesson plans and videos with tutorials and ideas how you can integrate our resources into your classroom.
We are working on a library of stand-alone versions of all the interactive simulations and widgets from our courses, which you can use on smartboards or embed in other platforms.

Polypad’s algebra tiles can be used to teach students how to add signed numbers.
Learn how to use multiplication by heart with students, including creating an account, importing students, and viewing their data.
Students explore the perimeter of shapes made from pentominoes. They learn to work systematically and construct reasoned arguments.
Students explore the internal angles of regular polygons, and decide whether polygons can be joined together without any gaps.
Students discover topics like factors, multiples, and prime numbers using a concrete, visual representation.
Students use tetrominoes as a context for exploring enlargements (dilations) and scale factors. Which “rep-tiles” can your students create?
Number bars can help students visualise different ways of making a specific amounts of money using 1p/1c and 2p/2c coins.
Students use algebra tiles in Polypad to to move between the forms x² + bx + c and (x ± m)² + c for a quadratic expression.
Students use number tiles in Polypad to develop a better understanding of remainders when dividing.
Students use fraction bars in Polypad to compare fractions with different denominators.
Students use algebra tiles in Polypad Students to move between the forms (x ± p)(x ± p) and x² + bx + c for a quadratic expression.
Students will use Tangrams to deduce properties of shapes drawn on a coordinate grid.
