This primary source kit offers history teachers the opportunity to use primary sources from the Maryland Historical Society to activate student interest in United States history and to encourage participation in National History Day. This source kit features original documents, images, maps, oral histories, broadsides, and a variety of other resources relevant to each year's National History Day. The teacher's guide features a set of activity sheets for use in gathering and interpreting data from multiple sources. All materials in the kit are reproducible for classroom use. Appropriate for use in elementary, middle, and high school classrooms, the source kit can be employed to teach economics, political science, civics, geography, and other facets of social studies. Context pages provide a way for teachers to familiarize themselves with the sources prior to their use and include the following information for each source: a bibliographic entry; the What? Who? When? Where? and Why?; a brief description with background information; reference to a secondary source with more information on topics explored; and research topics and discussion prompts. (BT)
