What an awesome and timely find (again through Twitter)! Scribble Maps allows you to write and mark on Google Maps and save your work. I thought this would be a great activity to review Westward Expansion (a rather intensive, detailed unit). The students got the hang of the activity rather quickly. They were able to outline the territories and put a place marker with more detailed descriptions (click here to see the above picture in website mode). I’m definitely looking forward to using the site again and also seeing where else it can be used!
