When it comes to keeping kids active, sidewalk chalk seems to brim with superpowers. How else could such a humble material inspire so many fun ways to get fit? Here are four activities that are sure to unleash the power (and playfulness) of one of concrete's most carefree companions.
Play this version of hopscotch just like the classic game of stone-tossing and skipping, but draw the board with 20 squares instead of 10 for twice the workout.
Never miss a local story.
Have each player take a turn jumping as far as she can from a designated spot. Use different colors of chalk to mark each player's distance. A kid playing alone can go for a personal best.
Hit the small mark
Draw a series of O's. From a designated spot, players take turns trying to hit each O with a tennis ball. (Draw the O's in front of a wall so that the ball will bounce back, or have another player catch each ball.) Play proceeds to the next player when an O is missed.
2-D obstacle course
Draw a meandering path (wide enough to run through), then inside it draw obstacles with instructions: a ladder ("Climb the ladder"), a high wire ("Don't fall off the wire!") and so on. Players must act out tackling an obstacle while standing on each drawing.
