These PowerPoint files contain figures from the text in electronic format. You might want to print out the slides in order to take notes, or you could incorporate these figures into your own classroom presentations.
If you do not have PowerPoint software for your computer, you can get a free PowerPoint Viewer from Microsoft.
Note: If your browser is Microsoft Internet Explorer, and you already have PowerPoint software installed, then the PowerPoint file may open up in your browser instead of being downloaded. If that happens, right-click on the link and save the file to your hard drive.
