This game is for two children.

Both players hold one of their hands behind their back. While their hands are held behind their back, they should choose a number from 1 to 5 and hold that number of fingers open. They could also use counters, cubes or sticks to represent the number (or the number could secretly be written on a piece of paper).

At an agreed time, they both reveal their hidden numbers. If the total of these numbers is even, Player A wins.

If the total is odd, player B wins. Children can then try with two hands or more counters, and perhaps find the difference between the two.

For juniors, try multiplying the two numbers revealed. Player B may have something to say about the fairness of the game after a bit!! (and will have learnt something!).
