Playing outside is an essential part of being a kid, but playing the same games like hide and seek and tag can get boring. Switch things up with other classic games that require little more than sidewalk chalk, jump ropes and a playground ball. These activities will keep the kids entertained all afternoon!

The object is to eliminate players in higher squares in order to advance to the "king" 4th square. Read the official rules on SquareFour.org.
