Pair up the children. In those pairs number them 1 and 2.
Get number 1's to create a circle. Then number two's stand in the middle of the circle and find out one fact about another number two. They then tell this to their partner (number 1).
The number 1's then swap places with the number two's, but instead of finding out a fact, they attempt to find the person who the fact is about by saying "do I know you?, you (e.g: like oranges, went on a skiing holiday)" If it is true the number 1 asks for their name then goes back to the number two and says the name of the person the fact is about followed by the fact. They both then shout the persons name followed by the fact. If it is true the person swaps partners with the other partners number two.
When everyone has swapped the game starts again.
