A simple SmartBoard Notebook file that contains a question asking students to decide which battle of the American Revolutionary War was the "turning point". The lesson should begin with a discussion of what criteria a battle has to fulfill to be a "turning point" in a war. Then, there is a weblink to a website with an interactive map containing all the battles of the American Revolution. Students work through the map, which is chronological and use the information provided to try to answer the original question. This activity can then be parlayed into a discussion, a written assignment or a presentation/movie making assignment. The file is easily convertible to PDF format if you choose to use it as a handout.
