When life gives them a problem to solve, Peg and Cat make lemonade — and get a lesson in bartering — in a refreshing new math adventure.
Peg and Cat are setting up a lemonade stand and decide to sell lemonade in exchange for ten marbles a cup. But the Teens say their price is too steep! So Peg and Cat keep changing their sign until they hit a price that has customers lining up. There’s just one problem: Peg and Cat forgot the cups! Can they barter their way back into business — or will they end up totally freaking out?
