This is a simple 2 player game suitable for children who are learning single figure addition facts.
Two sets of coloured counters and a calculator are needed.
Player 1 chooses two numbers from the list below.
Add the two numbers on the calculator. If the answer is on the grid place a red counter on that square.
Player 2 chooses two numbers from the list below and adds them on the calculator. If the answer is on the grid place a blue counter on that square.
Once a number has been covered it cannot be covered again.
The winner is the first person to put three counters in a row, across, down or diagonally.
There is obviously a clear advantage in going first, but it also helps to know addition facts, as this takes the guesswork out of playing the game, which is really an advanced noughts and crosses.
