Polypad is the ultimate collection of virtual manipulatives by Mathigon. It has ready to use polygons, number and algebra tiles, fraction bars, fractals , pentominoes, and much more. You can find Polypad under the Activities section of Mathigon. When you create an account, you can save your Polypad files and share them with your students with their links.

On the sidebar, there are two tabs; Tiles and Library. When you click on Library, you may see the files (manipulatives) created by Mathigon as well as your own saved canvases.

At the very bottom of the sidebar, you can find the links to the page "Sample Lesson Plans and Video Tutorials".

I use Polypad a lot in my lessons and wanted to share the links of the lessons that I prepared; (This list will be updated periodically.)

You can save as copies and edit them as you wish.
