Geogebra - a little from me and a lot from elsewhere!

This morning I have been working on Geogebra. It is a fantastic dynamic geometry/algebra package and has two killer features:

  1. It is Open Source, free and cross-platform, so all students and teachers can install it at home

  2. It has one-click publish to Web, so it is really easy to make dynamic resources available on-line

I produced this screencast, showing how to use sliders to control objects in a worksheet:


More importantly, though, I discovered Geogebra at JotSpot which has an awesome collection of screencasts, tutorials and pdf cheatsheets. Check it out!
