Math Circle 4 with Lesley University

Race to 100

The goal is to get 100 points. The challenge is you need to get exactly 100. 

Be careful! You automatically lose if you go over 100.

  1. Roll 2 dice

  2. Choose if you want to add, subtract, multiply, or divide the two numbers.

  3. Record your score for the round and add it to your previous total.

  4. Take turns following steps 1-3 until someone reaches 100 or everyone else loses (by going over 100).

For example:

  1. I roll a 2 and a 3. 

  2. I choose to multiply.

  3. I record my score of 6.

(I wait for the other players to take their turns.)

  1. I roll a 4 and a 4.

  2. I choose to multiply.

  3. I record my score of 16 and add it to my previous total.

(I wait for the other players to take their turns.)

Be careful when you get close to 100!

  1. I roll a 6 and a 4.

  2. If I multiply I lose. If I add I lose! So I’ll have to subtract.

  3. I record my score of 2 and add it to my previous total.
