Hopscotch

First, some hopscotch basics. Using your sidewalk chalk, draw a diagram like the one pictured above.
Toss the pebble into the first square. This marks the square that you will skip once you start hopping. If your pebble lands on a line, or outside the square, you lose your turn and will give the pebble to the next player.
Hop on one foot into the first empty square, and then to the next empty square and the next and so on and so on. Be sure to skip the one your marker is on. Jump with both feet on the squares that are pairs.
At 10, hop with both feet, turn around, and head back toward the start.
When you reach the square with the pebble, pick up the marker—stay on one foot!—and finish the course.
If you finish without any mistakes, give the pebble to the next player. On your next turn, throw the marker to the next number.
If you fall, jump outside the lines, or miss a square or can’t pick up the pebble, you lose your turn and need to repeat the same number on your next turn. The winner is whoever gets their pebble to 10 first.
