Line of Four (Addition)
This is a game for two players, using calculators. You will need one calculator each, and two sets of coloured counters (or circles of coloured paper).

1) Choose who will take the first turn.
2) The person who goes first should choose two of the numbers below:

2 3 8 10 14 20 51 67 99

3) Then, they should add these numbers together, and find the answer on the board below. Next, they should place one of their counters on top of this number on the board at the bottom of the page.
4) The other person should now take their turn (choosing two numbers, adding them, and placing their counter on the correct space on the board).
5) Take it in turns, repeating this process. The first player to cover four squares with his / her counters in a row in any direction is the winner.
