On a cozy morning hanging around the house, I brought snacks on a monkey platter to the playroom for us to pick at. Elijah and Sadie decided that they wanted me to price each snack and they would pay me for them with their fake dollar bills and real coinage. You want to pay for snacks? Yup- all giggles and money sorting. So I took some little yard sale stickers and priced each item with completely random and odd prices. They worked together sorting bills and change and each bought unlimited quantities of all of the snacks.
