Compressed Files: The PowerPoint Slides have been compressed to decrease file size and speed up downloading .  You will need to use "WinZip" to open compressed files.  You can download "WinZip" software from here.

If you do not want to use "WinZip" and don't mind a longer download time - the PowerPoint Slides are attached here in a non-compressed form

Most of the slides contain instructor notes.  To view the accompanying notes, you'll want to save the PowerPoint program to your computer.  Then open the saved presentation in PowerPoint and select notes view.
