With a handful of change in his pocket, your child is going on a trip to the city. Does he have enough money to cover all his expenses? In this second grade math worksheet, your child will practice adding, subtracting, and working with money to make change during his trip to the city. He'll decide which coins to give the bus driver to cover his fare, and how many coins he'll get back from the cashier for the cupcakes he bought at the bakery.
