Odd and Even
What happens when you add / subtract / multiply / divide with odd and even numbers?
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!).

I love this! We do this with addition. We have a 3rd player that says "Quick draw" to have the two students turn around and the player who says the correct answer first wins a point. They rotate positions. It's an intense game!
