Each person is given a small piece of paper on which they write down their name and a number. The number must be a positive integer. (A whole number, not zero). The winner is the person who has written down the smallest number that no one else has written down. Each person should keep their number secret.

When everyone has finished writing the teacher collects each of the pieces of paper in a hat (or similar) then, using a table on the board such as the one below the teacher reads out the names and numbers one by one. Each name is written next to the number they have chosen. If more than one person has chosen a number, that number is "out of the game"

The winner is the person who has chosen the lowest number that no one else has chosen
