Useful Links

• WolframAlpha is a great resource. It is a "computational knowledge engine", which means it does a lot of math!
• GeoGebra is a free program that is great for graphing functions and creating geometric diagrams.

Below are several sources for math videos. They do a good job of going through the skills but may not do a great job of explaining the concepts. They are continually getting better.

• Brightstorm has a bunch of videos of a teacher explaining topics. This link takes you to their math page. In the classes section, I have put links to individual lessons that might be useful for each unit.
• Khan Academy also has videos. These typically just have writing and voice.
