Mathigon dành cho giáo viênFree lesson plans, videos and resources
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.
Interactive Courses
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.
Virtual Manipulatives
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…
Teacher Dashboard
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…
Games, Activities and Resources
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…
Lesson Plans and Videos
Keep scrolling for many different lesson plans and videos with tutorials and ideas how you can integrate our resources into your classroom.
Widget Library – Coming Soon
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 Lesson Plans
Pentomino Perimeters
Students explore the perimeter of shapes made from pentominoes. They learn to work systematically and construct reasoned arguments.
Shapes Round a Vertex
Students explore the internal angles of regular polygons, and decide whether polygons can be joined together without any gaps.
How Many Rectangles?
Students discover topics like factors, multiples, and prime numbers using a concrete, visual representation.
Tetromino Reptiles
Students use tetrominoes as a context for exploring enlargements (dilations) and scale factors. Which “rep-tiles” can your students create?
Making Money
Number bars can help students visualise different ways of making a specific amounts of money using 1p/1c and 2p/2c coins.
Completing Squares
Students use algebra tiles in Polypad to to move between the forms x² + bx + c and (x ± m)² + c for a quadratic expression.
Remainder Riddles
Students use number tiles in Polypad to develop a better understanding of remainders when dividing.
Fraction Inequalities
Students use fraction bars in Polypad to compare fractions with different denominators.
Making Rectangles
Students use algebra tiles in Polypad Students to move between the forms (x ± p)(x ± p) and x² + bx + c for a quadratic expression.
Tangram Coordinates
Students will use Tangrams to deduce properties of shapes drawn on a coordinate grid.
