Find the Stars

What you will need:
Star shapes
Christmas pencils/pens
A prize

Make up some Star shapes in different sizes.
Make some type of marking on it so that players know it is one of your stars ( a symbol in the middle)
Place the stars around the building where the event is being held
Place them on stalls, On stall holders,near Santa's Grotto
Print off instructions sheets . (not how many keep them guessing) .

Sell the sheets at the start of the event with a free pencil
Have a posting point to return the answer sheets to at the end of the event
The person who has found all the Stars or the nearest number of stars is the winner of the prize
If two or more winners then pull out a winner.

The idea is that while looking for Stars it will attract them to look at everything in the event .
