What you need: one or more players, chalk, hopscotch marker (beanbag, keychain, rock)
How to play: Draw a hopscotch board of squares numbered one to 10. Taking turns, throw your marker into square one. If it lands without touching the lines (otherwise you lose your turn), hop on one foot in each square – unless the squares are side by side, where you can put both feet down – to the end of the board, skipping over the square containing your marker. Then turn around and hop back, picking up your marker on the way. On your next turn, throw your marker into square two, and so on. You lose your turn if you step on a line or miss a square. The winner is the first to get her marker to the square 10.
Fair-play tip: Got young hopscotchers? Start with a board that only goes up to five.
