If seeing is believing, then maps are belief in hard copy. This full-day NTC+ seminar explores three key questions related to historical cartography: What kind of historical evidence do maps provide? What can we learn about American identity by reading the maps that were made to depict travels, migrations, and tourism across multiple centuries? And, how can we use these dynamic and vivid primary sources in our K-12 classrooms as training modules through which our students engage with historical thinking? With a historiographical background on American cartography, this seminar gets participants used to reading and teaching with maps in a variety of new ways, and will invite participants to work directly with both the Newberry Library's exhibit, Crossings: Mapping American Journeys (February 25 - June 18, 2022), and related digital resources developed from this exhibit for classroom use.
