Set up your own agility ladder by marking off squares in a line indoors with masking tape or with chalk on the driveway or sidewalk. Then let children determine their own activities and rules: Will they hop on one foot in each square, or alternate feet while skipping every other square? Will they hop into the first square on both feet, the second square on just their left foot, and so on? Kids love making up their own sequences. You’ll be amazed at how many different ways they can figure out to use a simple ladder drawn on the ground!
