This post was inspired by a request for help from one of my colleagues. My colleague wanted to know more about how to use GeoGebra in his classroom. Not being a mathematics teacher, I didn’t have a lot of ideas right off the top of my head but I did know of some links to send him.

The GeoGebra website you will find the GeoGebra Wiki which lists teaching materials and directions by grade level and content area. If you’re a first-time or relatively inexperienced GeoGebra user, you will want to check out the GeoGebra quickstart guide and introductory ebooks. To ask questions and converse with other teachers using GeoGebra, the user discussion forum is the place to go. Finally, visit the GeoGebra YouTube channel for video tutorials.
