Activities

Grades:

Check out our newest tool! The Dynamic Paper application allows you to create images of nets for 3‑D shapes, tessellations of polygons, number grids with any number of rows, columns, and integers, spinners with various numbers of sectors, and more! You can then create a PDF worksheet with the images you choose, or you can export the images to JPEG format for use in other applications or on the web. Check it out!
