A couple of colleagues of mine have been showing me things in Geogebra. I tried it this week with a unit circle problem. It turned out great. I had each student/pair with a computer in front of them. We went over the Unit Circle and the students used the laptop or iPad to maneuver around the GeogebraTube post that I had made. My colleague called this COMPANION Technology. (They used it with their learning) Many of the students started out using the digital Unit Circle and manipulating it. However, as time went on, many stopped using the digital technology and just did the work in their head or on paper. There was a homework assignment that involved the digital Unit Circle that I had made in Geogebra. About half of the students ended up needing it. The next day the unit circle questions and discussions were amazing. They really had a conceptual grasp of it.
Here is the link to the

Steps I took to get this up and running.
1. Download Geogebra to your desktop.
http://www.geogebra.org/cms/en/download/
2. Make an interactive Geogebra File. (see intro to geogebra youtube:

3. Save the file to a place where you can remember to retrieve it.
4. Go to Geogebratube.org
http://geogebratube.org/ You will need to login.
5. Upload your file to Geogebratube and fill in all needed information.
6. Get the link of your upload and distribute it to your students.
I hope you can give Geogebra a try,
Dave
