I would use map builder for a lesson on geography or history lesson. Students could start their geography lesson by building their own map builder with all the places they have visited and get a visual idea of how close different states and cities are. They can then take map builder further into a history lesson and locate different historical places and in the description part write a small memo on what went on their. Students can focus on a few states and find historical events that went on in their states and then each student can share their findings with the rest of the class, just by clicking on their city and reading the description part about it.
