A voicethread that includes all of the above, plus some ideas for using geogebra with your students.

Here are the few worksheets/activities I have so far, most of which I have referred to somewhere in my blog. These are links to the webpage versions of the worksheets and all are welcome to use, download and edit as you wish, but I think you have to join geogebratube.org in order to do that. Some of these I made from scratch, and some I got from geogebratube or straight from generous teachers.
