TitleReviewing rod relationships and the candy bar problem, Clip 5 of 6: Comparing one half and one third, part 1
PublisherNew Brunswick, NJ: Robert B. Davis Institute for Learning, , c1993-09-24
DescriptionIn the fifth clip from this classroom session, researcher Carolyn Maher asked the class to compare one half and one third and determine which is larger and by how much. The class worked on this problem for the remaining ten minutes of the session. During a brief whole class discussion, Laura and Jessica shared their model of an orange and red train, three purple rods, and two dark green rods. Jessica explained that one half was larger than one third by the length of a red rod. The researcher asked the class what number name they would assign the red rod in Jessica’s model. Alan suggested that it should be called one sixth. With that, the researcher closed the discussion by noting that this was a point that would have to be explored further and that they would continue working on this problem during the next session.
