Number Mastermind (Place Value): Write a two-digit number on a piece of paper. Challenge students to guess your number by writing the following clues on the board after each guess. Use the following code:
* Correct digit in the correct place
O Correct digit but not in the correct place
X Nothing is right
When students are able to do this successfully, try the same activity with 3 digits.
Perimeter/Area Challenge: Provide each student with graph paper. Write a specific number of square units on the board and have students see how many different ways they can show this on the graph paper. This activity can also be done with perimeter.
I Have Nothing: Divide the class into two teams. Each team will start with 100 points and the first team to get exactly zero wins. The team that begins the game may subtract up to 10 points. The next team may subtract up to 10 points more than the previous team. Play goes back and forth until 1 team reaches exactly zero.
