What I've done on this page is linked the topics to the actual PowerPoint Presentation that I used in class.  To access them just click on the link to the topic and follow the directions to access the presentations.  If you don't have PowerPoint on your computer you need to download the PowerPoint Viewer that is available for free through Microsoft Office.

Teachers:  If you would like to save the files themselves so you can edit them and use them in your classrooms you will need to right click on the link and choose the "save target" option.
