This is a matching review game for the five themes of geography, basic map skills, and primary and secondary sources. It reviews definitions and examples. Print pages 1 and 2 on one color of paper and pages 3 and 4 on a different color. Cut out and put all in a zip lock bag. Have groups work to identify matches...pages 1 and 2 match with something on pages 3 and 4. I have kids first find matches while looking at all the cards. After that they play memory with the set and find matches while the cards are turned over.
