Maps
Do you know those free maps you can pick up at rest stops? They are great for kids’ art projects! Paint the tread on some of their toy cars and let them drive over it for cool track marks. Or, they can practice their pencil/crayon control by trying to trace over the lines. Not to mention, all of this gets children thinking about maps and how to read them.
To include adults, those maps also make cool artwork to hang on a wall. Especially if it is a place you’ve visited. You can jot a few notes on the map before hanging or include pics of you and your friends.
