How did the Erie Canal, canals, roads, and railroads help to link the United States together? Students will complete the scaffolding questions based on the reading passages discussing the ways in which canals, roads, and railroads help to unify the United States. They will then create a postcard imagining they are a person taking, building, or observing someone using a newly built canal, road, or railroad. A fun and engaging lesson and activity!Included in this resource:• Cover Page• Student-
