U.S. Imperialism in the Philippines--should the U.S. annex the Philippines? This one to two day lesson includes involves political cartoon and primary source document analysis and a writing assignment on the U.S. annexation of the Philippines. It is suitable for standard or AP classrooms--I have used it in both!
There is a powerpoint with background information and political cartoons, a graphic organizer for cartoon analysis, and a series of primary source documents with analytical questions.
Explanation of the lesson and a few variations is included in the file.
