If you're a mathematics educator, you'll find the GeoGebra site to be a perfect addition to your stable of online resources. On the top of the homepage, visitors can look through sections that include About, Download, Community, and Materials. Most visitors will want to download the GeoGebra application as it is the primary way to utilize the 44,000 learning activities offered on the site. After completing the download of this free, interactive geometry, algebra, statistics, and calculus software, click on over to the Featured Materials area. Here visitors can look over the newest materials, check out the Best Worksheets, and wander through the popular tags. Mathematics educators have contributed many of the items here, and a small sample includes "The 11 Patterns of the Cube" and "Introduction to Linear Equations." Finally, visitors can also use the Community area to ask questions and share resources.
