The Monty Hall Problem

My Year 6's have asked me to explain this. The problem goes like this. There are three boxes. Only one of them has a prize. After you have picked a box, the game show host opens one of the other boxes that has nothing in it (the game show host knows what is in each of the boxes). He then gives you the chance to switch boxes or not. What do you do?
