Comparing fractions and evaluating models that represent solutions, Clip 2 of 8: Comparing one half and one third, Jessica and Erik
Abstract (type = summary)
In the second clip from this session, researcher Carolyn Maher asked the students if they felt confident to justify their solution to the problem: Which is larger, one half or one third, and by how much? Jessica built a model of an orange and red train, two dark green rods, three purple rods, and six red rods at the overhead. She named the rods one, one half, and one third, and one sixth, respectively. She then became flustered, indicating that she forgot what she was going to say, and asked Erik to help her out. Erik repeated the number names for the rods, and then recapped his argument and said that one half is larger than one third, but two thirds are larger than one half. He then showed that if a red rod is placed next to the purple rod, the length of that train will equal that of the dark green rod. He explained that Jessica meant to show that orange and the red train was one, the dark green was one half, the purples thirds and the reds sixths.
