Here's a great little ice breaker for kids' parties - a very simple treasure hunt that can be themed around your event. Cut out some themed shapes from card in advance - so you might make up easter egg shapes for an easter hunt or Christmas tree shapes for Christmas parties. Mark the back of a few shapes with an X and then hide them around the garden or house. Any child that finds a shape with an x marked on it can trade it in for a prize. Simple but fun!
Collect small containers to put sweets in as a variation.
