The class is US history to 1877. Think of the themes that cover US history over this time. 

Discuss the changing concepts of freedom in the United States from the colonial period through reconstruction. 

Discuss political parties in the United States during the same time frame. 

These types of questions. As always, you will need an introduction, a main body with numerous specific examples to pack up your statements, and a conclusion. This should be 2 to 3 pages long.
