**NEW!** Download a GeoGebra guide for Algebra 1 and 2

GeoGebra is a powerful, open source, dynamic geometry software. It is free to download, and is very easy to use. It is also simple to create interactive applets with GeoGebra. You can incorporate exploration questions through these applets and create a truly interactive learning experience.

Unlike standard graphing software, GeoGebra lets you *move* a graph around with your mouse once you create it. It lets you experience the connection between geometric transformations and the corresponding algebraic representations.
