Abstract (type = summary)
In the third clip David, Meredith, Erik, and Alan worked to build models on the floor using rods. David built a model to test his conjecture, while Erik continued working on the thirty-six centimeter model that he had begun building previously. He made a train of three orange and one dark green rod and lined up four blue rods. Alan continued to argue that Erik’s model would not work since he wouldn’t be able to third because he didn’t have big enough rods. Erik then showed Alan that he had found a way of showing thirds in his model. He lined up three blue rods and nine white rods against the model and showed that three white rods could be added to each blue rod to complete the third. Erik was asked by a visiting researcher to re-explain. He repeated his explanation and said that it was as if he made a new rod. The researcher asked Erik if there was another way to arrange the rods that he had used to show thirds. Meredith placed three white rods after each blue rod and Erik explained what she had done.
