TitleComparing fractions and evaluating models that represent solutions, Clip 4 of 8: Comparing one half and one third, different number names for the white rod
PublisherNew Brunswick, NJ: Robert B. Davis Institute for Learning, , c1993-10-01
DescriptionIn clip 4, researcher Carolyn Maher asked the class to determine the number name for the white rod in the first model that had been built, in which the orange and red train was called one. James, Laura, and Brian suggested number names. The students then worked in their groups to build a model and determine the number name for the white rod. Meredith and David, without building the model, named the white rod one twelfth. During the subsequent whole class discussion, James revised his solution. He lined twelve white rods against the original model and said that the white rod would be called one twelfth. To justify his solution, he counted the white rods aloud. Beth and Sarah then presented two alternative justifications for the number name one twelfth.
