1. Work with your partner. Sit side by side with a divider standing between you. 2. Player 1: show different times to the hour and half-hour on the clocks on your grid without letting your partner see your work. 3. Player 1: Give clear instructions to your partner on how to complete his/her clocks to match your grid. For example, you might say, “show five o’clock on the clock in the center of your grid”. 4. Remove the divider and look at your two completed grids to see how closely they match. 5. Swap roles and play again.
