MountVernon.org offers a handful of nice online resources for learning about the life of George Washington. One of the featured resources is an interactive map that is titled Washington's World. Washington's World includes a timeline and dozens of placemarks. Students can explore the map by panning, zooming, and clicking on the placemarks. Students can also click markers on the timeline to jump to corresponding placemarks on the map.
Applications for Education
Washington's World is a great map, but some of the information in the placemarks is incomplete or not present. A good assignment for U.S. History students would be to create their own version of the map and fill in the missing details. Google Maps and Google Earth could be good platforms for students to use to create their own versions of Washington's World.
