GeoGebra - free dynamic mathematics software
Description
GeoGebra is an open source software that links dynamic geometry with algebra and calculus. It aims at middle and high school math education. The software can be used both as a teaching tool to explore and discover mathematical properties and as a tool for the creation of interactive teaching materials (e.g. dynamic webpages).This software was developed by Markus Hohenwarter, a member of the "Standards Mapped Graduate Education and Mentoring" MSP in Florida.
