For each of the 50 states and capitals and their corresponding QR code, cut the paper in half splitting the state from its capital and the QR code in half. Then mix the papers together. Students will then match the state to the capital. To check their work themselves, they scan the QR code. If the match is correct, the QR code will scan and the state and capital will read on whatever device is being used. If the match is incorrect, the QR code will not scan.
