GeoGebra is a popular free program used by high school mathematics teachers and students. GeoGebra use doesn’t have to be limited to high school use. Through Mathematics and Multimedia I recently learned about GeoGebra Prim. GeoGebra Prim is designed for use by elementary and middle school students. The tool set on GeoGebra Prim is smaller than that of GeoGebra. The tools are also designed to be easier for younger students to use. Granted I don’t use GeoGebra very often, but when I tested Prim this evening and did find it easier create and measure objects than the first time I tried GeoGebra. You can read more about GeoGebra Prim here and download it here.
