This applet simulates the use of an actual geoboard without the usual limitations of working with rubber bands. Geoboards are used to investigate shapes, area, and perimeter. With this applet, students have choices about the number of pegs on the geoboard and the number of rubber bands. They also may select to have the area filled in within the shapes or merely work with rubber band outlines. Most materials designed for real geoboards may be used with this online version. There is also an instructional animation which shows students how to add and remove shapes as well as display and hide side lengths and the area / perimeter of the shape created. Less
