In this game, inspired by a similar version from the book "Game On!" by Pat Doyle, a bit of math adds an educational twist to hopscotch.
Setup: Draw the hopscotch area to resemble a calculator
The first player tosses her stone on the "1" key. She then hops on an equation equal to 1 (for example, she might jump to the following keys: =, 1, +, 0 or =, 3, -, 2). Players use 1-footed hops when landing on odd numbers and zeroes, and 2-footed hops for even numbers and symbols. A player's turn continues until she makes a mistake, such as stepping on a line or hopping on an incorrect equation. The winner is the first person to work through all the numbers to 9.
