This activity has students look at some of the major causes of the Great Depression. It can be used in many ways. I use the activity as a jigsaw lesson. Groups would research one cause of the Depression and then they would break up and share their cause with the other students, thus helping all students analyze all of the listed causes. It could also be a partner or independent activity.
You could treat this as a webquest or just a worksheet to accompany a discussion, lecture, or just about any textbook.
