You know those racetrack rugs you can find in Target or on Amazon? My son loves his and it got me thinking, why don't we just make our own?!
You need a big piece of cardboard (flattened), markers and some fun cars.
Get your kiddo to help design your unique racetrack. Let him/her tell you where they want the roads to go, turns, crossroads, etc. (They will love being involved in this part). You can even add trees and bridges, etc.
Then have fun using your imagination driving the cars. You can even put people figurines or animals on the side of the roads to make it a whole scene!
