Use it in your class to teach your children about the 100 parts of a whole. Describe to your children what the percentages mean and have them look at what happens when they add parts to the park. They will notice that all percentages change, but all add up to a total of 100% (or 1 whole park).
This game also work with fractions and decimals and is a great way of teaching the children the equivalent decimals and fractions to the percentages.
