These free United States History course materials are designed for junior (grades 7-8) and senior (grades 9-12) high school students. Standard high school courses textbooks limit the scope and sequence of this curriculum. Following traditional practices, our materials are arranged chronologically, with some allowances made by topic. For example, the "Decades of Change" unit (1960-1980) looks at the social and political upheavals of the 1960s, with spilled over into the 1970s. But of course, the civil rights movement had its beginnings long before 1960.

Our materials are thus limited in sequence (yet cover all of American history), while not being limited in scope. We are not bound by what can be contained within a physical textbook. Ergo, we are able to offer items on topics not always (or ever) covered in any great depth in high school classes. Educators are free to pick and choose what topics to cover, and how deeply to pursue these topics.
