Lay flash cards out around the play area and challenge players to find them in a specific order. For example, you might have players move from card to card in order of the magnitude of the answers. The players would first go to 2 x 2, followed by 3 x 5, followed by 4 x 8, and then by 6 x 7, because they are in order from smallest to largest answers. For a variation, have players find facts in similar families in order, such as 10 - 1, 10 - 2, 10 - 3, 10 - 4 and so on. One final variation is to challenge players to find flash cards representing related facts, such as 3 + 4 = 12, 4 + 3 = 12, 12 - 3 = 4 and 12 -4 = 3.
