In "One Hour", the FBI is chasing kidnappers who demand a $3.2 million ransom. The FBI thinks this number has a personal value to the kidnappers, but Charlie disagrees. He compares the division of the money to dividing a cake among a group. Charlie explains that if two people agree to divide the cake, cutting the cake in half may not please both people if, for example, one person prefers extra icing. Students explore fair ways for two people to share a cake, and extend this to more participants.
