The unit is made up of 24 exercises that together form a mosaic of American life during these years. Each exercise includes reproductions of documents from the National Archives and suggests classroom activities based on these documents. It also includes a booklet containing a teachers guide plus a set of reproductions of original documents. A CD-ROM contains exercise worksheets and digital images of original documents including personal letters, news clippings, photographs, graphs, maps, and telegrams which reflect a wide range of social, political, economic, and cultural themes of the decade as seen from the points of view of citizens who corresponded with the federal government. Students practice the historian"s skills as they complete exercises using these documents to gather information, identify points of view, weigh evidence, form hypotheses, and draw conclusions.
