Created in partnership with Education Development Center, Zoom In features 18 skill-focused, document-rich lessons on social history topics that address every era of U.S. history. These interactive inquiries engage students in reading documents closely, gathering evidence, and writing an argumentative or explanatory essay. Each lesson includes all the materials teachers need— a compelling hook, slides with essential context, a variety of historical sources, carefully designed reading materials, and discussion prompts and templates for writing well-structured essays.
