TitleFraction as number, an introduction, Clip 5 of 8: What is the unit?
PublisherNew Brunswick, NJ: Robert B. Davis Institute for Learning, , c1993-09-20
DescriptionIn the fifth of eight clips from this session, researcher Carolyn Maher asked the class to give a number name for the red rod if the brown rod was called one. Danielle explained that it would be called one fourth and could be justified by placing four red rods next to the brown rod. The researcher then asked the students a related question, requiring them to name the brown rod if the red rod was called one. Jacquelyn explained that if the red rod was one, the brown rod would be called four, because four red rods equal a brown rod. The researcher then challenged the students with one last problem. She asked them what rod would be called one if the white rod was called one half. Laura responded that the red rod would be called one, and Graham justified Laura’s solution by saying that this could be shown by placing two white rods next to the red rod and seeing if they were the same length.
