Roll of electrical tape
Open floor (tile, laminate, concrete, or wood)
How to:
This doesn't have to be perfect to get the job done. Using your electrical tape make a square, then rectangle with a line in down the middle (resulting in two squares), square, square, rectangle with a line down the middle, and then a single square. Really you can arrange the hopscotch however you would like. Ta da! Let the kiddos have some fun!
*If you put this in a high traffic area (such as your kitchen) be prepared to see visitors test out the hopscotch. Everyone loves to bring back childhood memories :)
