Divide the class into equal groups of buyers and sellers. Hand out Pizza Score Sheets 7D, one per student, on which students will record their transactions. Each buyer and seller can transact only one pizza at a time. Announce that the market is open for pizza sales. Sellers and buyers meet in the center of the room to agree on price for pizzas.
Any buyer can talk with any seller.
Students should watch the sale prices on the transparency, so they know what prices are being paid. As soon as a sale is made, buyers and sellers turn in their cards and take new ones. Students try to make as many sales as they can until the5minute round ends, keeping records for each sale made. Give recognition to the winning buyer and seller. Replay the round and ask students to calculate their gains and losses.
