As a kid I loved playing with fake money and well the real one but my parents weren& all that keen on that. I was running my own pretend store, was buying up properties in Monopoly and just enjoying having a few piles of money at hand.
Print out several copies of the play money page. Cut out the play money. Use Crayola® crayons, colored pencils, or markers to decorate the play money. Use this special money to play pretend store, bank or whatever else you can imagine.
