Play the license plate game. You don't have to be in a car to play. You can look at the license plates of parked cars. Suggest your children keep a record of the states whose plates they have seen. They can color in those states on a map and illustrate them with characteristics described on the license plates.
Some states have county names on their plates.
If you live in one of these states, your children may want to keep track of the different counties. Go around your house and look at where different things come from. Examine the labels of the clothes you wear. Talk about where your food comes from. Perhaps your climate is too cold for growing bananas, and the milk is too perishable to travel far.
