HELP explaining Pascal's Wager!?

need some help! I have a big paper due soon for my philosophy cl. It requires me to take Pascal;s wager and turn it into something that an average fifth grader can understand fully. Does anyone have any ideas or tips? All I can come up with is casino, racetrack, and tooth fairy/santa claus comparisons, none of which fit the age bracket. Anyone that helps, THANK YOU!
