Links to Resources
Here are a few of Dr. Math's favorite resources along with a brief description of what to expect from each. As much as possible, we have attempted to limit this to resources that are free, since free is always good!
Geogebra is a free graphing site that performs many of the same functions as an expensive counterpart, The Geometer's Sketchpad. The software can be downloaded to your computer, and there is a mobile version as well. You can create an account with Geogebra and save your files for future use. Dr. Math has used Geogebra in many of his conference presentations. Here is a link to one of his files involving Transformational Factoring.
