Here’s an advance look at some of the “This Day in Geographic History” (TDIGH) events coming up this week. For each date, we’ve matched it with a map or visual, background information, and a classroom activity so you can plan ahead.

TDIGH: Paper Money Introduced in U.S.
The Massachusetts Bay Colony printed the first paper money, called a “bill of credit,” in 1690 in what would become the U.S.
Background: The History of American Currency
Activity: Read about the dollar’s influence around the world and review financial vocab. For a vocab game, divide the class into two teams, put the words on the board, call a student from each team to the board, say the definition of a term without saying which term, and students must tap the correct term on the board as quickly as possible- whichever student taps the correct term first, his or her team gets a point!
