TIMS Task

Demonstrate the activity by having you lead and the class follow. After students understand the activity, ask students to work with a partner to continue to practice their partitions of ten. Remind students to show numbers between 5 and 10 with fingers on one hand and then several more fingers.

B. Partition Ten

Stand up and find a partner.

  1. Face your partner.

  2. Player 1 puts his or her arms straight up in the air.

  3. Once in the air, Player 1 uses his or her fingers to show a number between 0 and 10.

  4. Player 2 puts his or her arms down and displays the number needed to make ten. For example, Player 1 shows 4 fingers and Player 2 shows 6 fingers because 4 + 6 = 10.

  5. On the next turn, Player 2 leads.
