This 27 slide presentation is perfect for providing background knowledge to students beginning a study on WW2. I've used it primarily with 5th grade students, but it's written so that it's understandable for students 4th grade and up. Several slides contain hyperlinks to youtube videos showing the Blitz of London as well as Pearl Harbor. The presentation gives a broad overview of both the European and Asian aspects of the conflict. It would work well to use as a center or whole class.
