This includes a lesson plan and all resources required to teach students about the varying perspectives on isolationism and intervention that the United States weighed in the 1930s while Germany and Japan were expanding. A PowerPoint presentation will guide the lesson and prompt a warm-up and closure question. Students will participate in a continuum activity regarding suitable reasons to go to war, and then participate in a jigsaw activity. Jigsaw topics include the Nye Committee, the Lend-Lease Act, the Neutrality Acts, the Four Freedoms, and the Atlantic Charter. Excerpts from the Four Freedoms and Atlantic Charter are included to challenge high-level students.
