As I walked down the hall to my classroom, I noticed these wonderful interactive foldable graphic organizers. These were done by our fourth grade teacher (who got the idea from one of our first grade teachers, who's 4th grade child had done it at her school), but I don't know who to credit for the original idea.
I love how they incorporated the map into the graphic organizer. I've been trying to come up with something similar for a topic I teach.
Inside, they defined each of the regions and drew pictures of the characteristics specific to that region.
