This PowerPoint covers an entire unit on the 1920s for a US History course. There are links throughout to additional resources, as well as extensive notes for teachers when viewed/printed through PowerPoint. This is meant to support textbook materials, but certainly (depending on your textbook's publisher) can be used as the main resource while the textbook is more supplementary.
This presentation includes:
1. Links to videos, song samples, research sources
2. Maps and political cartoons for analysis.
3. Many photographs.
4. Suggestions from having taught this unit myself (what worked, what you may want to consider adding, etc.)
Depending on your version of PowerPoint, some minor formatting changes may need to be made (shifting text boxes). This is a really easy fix. :)
