Hi! I was just wondering if anyone has any ideas for teaching a lesson on Imperialism in America for AP US History. I have a challenging class situation. I am team teaching with a more experienced teacher and we have basically combined two classes. There are over eighty five students in the class at the same time. This makes many classroom activities difficult. However, the class period is 85 minutes and direct instruction for that long is just too difficult for the students. Any good ideas or activities that would work well for a large group of eleventh graders? Thanks!
