U. Making Twenty
Stand up and find a partner.
- Face your partner.
- Player 1 puts his or her arms straight up in the air.
- Once in the air, Player 1 uses his or her fingers to show a number between 0 and 20. To show a number greater than ten, show all ten fingers then close both hands and quickly show a number between 0 and 10.
- Player 2 puts his or her arms down and displays the number needed to make 20. For example, Player 1 shows 14 fingers and Player 2 shows 6 fingers because 14 + 6 = 20. Another example is, Player 1 shows ten fingers then quickly shows 3 fingers and Player 2 shows 7 fingers because 13 + 7 = 20.
- On the next turn, Player 2 leads.
