Students are assigned one of six minor political parties to gather information about, and then create a poster displaying the minor political party information. Then, posters are displayed in the classroom for students to have a "gallery walk" and complete a chart about all six of the minor political parties on the posters.
This is a simple way to reinforce differences among minor political parties and knowledge about minor political parties. Students typically spend two days in class creating the posters (30-40 minutes each class), and then one class reviewing all of the posters, plus an additional assignment to summarize minor political parties and their role in the US government during the class in which the gallery walk occurred.
I included the poster assignment, gallery walk chart, and pages of information about minor political parties that could be given to students if internet access is unavailable.
