Mrs. Berry's weekend math assignment is one of the toughest ever. In fact, she seems to have gone a little overboard - she thinks pennies have incredible powers! Powers like curing diseases, building schools, and delivering food and medicine. Mrs. Berry wants the class to explain how this can be. Isaiah, Sandy, Dennis and Stephanie decide that as members of the Millionaire Kids Club, there's no money problem they can't solve. They're up for the challenge! But as they start their research, they also discover that Sandy has a money concern of her own - her mom has lost her job. Can the pals solve their crazy penny homework and help Sandy feel a little better at the same time?
