How it works
Brookfield is a made-up town of six families beside a river. The children walk a muddy path, and the families decide they need a bridge.
A bridge costs 12 coins, too many for one family alone. So each family puts 2 coins in a big pot.
Coins put in for things a whole town shares are called taxes. A tax is a share we all put in for things we all use.
Real grown-ups pay taxes from the money they earn, but these are pretend coins. It is fair, because everyone puts in a little and everyone can use what it pays for.
