Learner.org offers a collection of map-based lessons and an interactive map about the United States. After completing the map-based lessons and trying the interactive map, students can test their knowledge with a short quiz. The map-based lessons include content about Native Americans, the 50 states, colonists, and westward expansion.
Applications for Education
The Learner.org map-based lessons and interactive map are probably best suited to use in an middle school setting or as a review of the basics for high school students. The map-based lessons do require students to do a fair amount of reading.
