Other forms: hopscotches
Hopscotch is a game in which players hop on one foot between numbered squares on the ground. Playgrounds and driveways are common places to see hopscotch being played.
To set up a game of hopscotch, you need a grid of numbered boxes, often drawn on the sidewalk with chalk. Each player takes turns tossing a small rock or other object into one of the boxes, hopping on one foot, picking up the rock, and hopping back. The object is for the rock to land inside each box without touching a line, and for the hopper to also avoid landing on a line or losing balance.
