Counting to Determine Quantity

Delivery Method: 

Three children work with their teacher to assign prices to cartons of eggs from the pretend store in their classroom. The children begin by thinking about how they can use the size of the cartons to calculate prices. Then they open the egg cartons and discover the holes inside. The rows of identical holes encourage the children to shift from thinking about size to considering how quantity relates to price. Observe what knowledge about numbers the children demonstrate. Notice what strategies they use to help them count and learn about what problems the children encounter. As the children work to determine the quantity of eggs held by each carton, they demonstrate their knowledge of counting and understanding of numbers and the number system.
