  1. Collect 12 quarters and 8 dimes.

    2. Stack your coins according to the following rules.
      • Quarters have to stay with quarters, dimes with dimes.
      • All coins must be used.
      • Each stack must have the same number of coins.

     

  2. Repeat the coin activity with a larger number of coins, 128 quarters and 96 dimes. What is the largest number of coins you can get in each stack if you follow the same rules stated above? How many stacks of each type of coin would there be? Try to figure this out without actually using coins.
