Docs Teach from the National Archives has a lot of great activities that incorporate primary sources and use great digital tools. A newly published activity helps students to analyze treaties through Treaty Making.
Students will read and analyze the text of six early treaties between the U.S. government and Great Britain, Russia, and several Native American tribes, and answer a few essential questions. Through close examination of the documents, students will expand their understanding of the original sovereign and separate nature of American Indian tribes, their legal status as independent governments, and the purposes of treaty-making between governments in general.
Students use the Mapping History tool to link primary sources spacialy on a map and incorporate existing treaties for analysis and discussion. Students then participate in a hands on activity that requires them to create a treaty of their own. The lesson plan is fully mapped out with Common Core alignment. Check out this great lesson here.
