Gillispie “Gems” of the Week
February 17, 2011 In math we have been practicing counting by fives. The children may not realize it, but as they learn to count things in groups of five or ten, they are actually learning the basics of multiplication. Here you can see us counting our fingers on the carpet. We realized that each person has five fingers on each hand, so a quick way to count all of our fingers is to count by fives. Today, we played the Raft Game, which is always a kindergarten favorite. Children roll a die and count out that number of beans. Each time they collect five beans they trade them in for a “plank,” which has five beans glued to it. Once they’ve collected five planks, they trade them in for a complete raft. At that point they can ferry their bear safely over the river. The children are learning the concept of a “fair trade:” five beans for one plank, five planks for one raft. This practice will help them as we start to learn about coins and exchanges with money: five pennies for a nickel, five nickels for a quarter.
