Name: Target Number
  You may simply turn it into an activity to review numbers.
  In that case, just have Ss take turns guessing and don't even need
  to divide the Ss into teams.

Materials:
  1. a marker
  2. a piece of paper

Plan/Procedure:
  1. Write down a number between 1 and 100 on a piece of paper w/o having Ss see it.
  2. Divide the Ss into two(or more) teams, and do any competitive activity.
  3. The winner(or loser) from each round gets a chance to guess what the target number is.
  4. If the player miss it, declare the new range of the target number by saying, "The target number is between 1 and Ｏ(or Ｏ and 100)."
  5. Repeat steps 3 and 4 to narrow the range till the target number is hit.
  6. The team which hit the number wins(or lose).

[Actually, i played the game with some seven-year-old students of the other teacher before my class' started, and they loved it. I realized that the next time they were looking for me. I guess they wanted to play it again.]
