Introduce WWII through images from the war. This is a PowerPoint of iconic pictures from WWII. Students will write short descriptions on each picture and then determine a them for each group or cluster of pictures. At the end students will write a short paragraph reflecting on the activity.
I use this in 10th grade US History to introduce WWII. It could also be used later in the unit to assess or even reteach. There is a lot that can be done with these pictures.
