Mr. Meyer has a great idea for an interesting social studies activity: "reverse engineering" bank notes and license plates.
Basically, he recommends collecting pictures of currency and license plates, using Photoshop to edit out explicit references to their origin, and challenging students to examine the clues on the pictures to figure out which countries/states use those items. This is a good activity for analysis: think of all the historical figures, symbols and other visual elements used on money and license plates. Why were those features chosen to represent the nation or state of origin? That's a good question for your students!
Mr. Meyer also posted sources on where to find pictures of bank notes and license plates. Check out his blog for more details!
