Learning About the Number Balance

On Friday before break Mrs. Lamphier, our Math Coach came in to teach a lesson about addition using the Number Balance. She talked to the children about how the tool can be used to prove if an equation is true or not.  You could hear and see the wheels turning as the class puzzled many ways to balance out a number- if you put an 8 on one side of the scale you could put a 6 and a 2 on the other or also two 4's, a 1 and a 7 or a 3 and a 5!
