The Geometer's Sketchpad

Seventh graders draw varying types of polygons and find the sum of their interior angles using the Geometer's Sketchpad. After drawing the polygons, 7th graders transform them by making small variations and describe their results. Using the polygons they have created, students determine how to use them to tile a plane.
