Use the “Pan Balance” game to continue to explore how you can determine unknown weights of different shapes.

Each shape has a predetermined weight. Your task is to explore how the weights of certain shapes compare with others.

  • Select a shape and place it on one pan.
  • Continue to select shapes and place them on either pan. When the pan balances, the program will save the configuration.
  • Reset the pan and re-select different shapes that will result in a balanced scale.
  • When you have enough clues about how the shapes balance, you can guess the weight of each shape.

There are six sets of problems. Try several sets to challenge yourself!

As you work through each set, see if you can determine the minimum number of configurations you need in order to determine the weight of each shape.
