This is an activity I use in my Geography Unit to encourage students to be able to quickly identify each of the 50 states. This challenge is based on accuracy and then by time. Included are instructions, numbered states map, answer key, certificate to print off for the winner, and an Excel spreadsheet already set up with simple instructions to generate a master list.
