This site is full of links that can be used when studying the American Revolution. It covers key individuals, spies, battles, causes of the war and a lot more. There is also a timeline link that could be used to teach about timelines.
This website is linked with a lot of information and resources. What I thought was awesome about this site is that it has actual letters written by soldiers and families of soldiers. During a unit on the Revolutionary War, materials like these are priceless and so much more meaningful that words from a textbook.
This fascinating site is filled with information about spies during the America Revolution. Users can explore the letters of spies (both in their original format and a transcribed version) and their stories and techniques. In addition, the site offers a timeline, more information about people of the revolution, and a teacher's lounge with activities and suggestions for using primary sources with all students.
