This essential set offers detailed, but accessible, overviews of the most indispensable topics of the social studies curriculum, including the Constitution, the American Revolution, the civil rights movement, and much more. Each book offers beneficial historical images to support the narrative as well as a concluding timeline for a helpful review of important dates. Features include: Extended glossaries that define central vocabulary terms important to the discussion of American history topics. The most important historical figures, documents, and events are introduced in context within each volume. A solid resource to review fundamental curricular topics, which also supports English Language Arts Common Core standards.
