Abstract (type = summary)
In the sixth clip Erik and Alan worked on the task: Which is larger, one half or three fourths. Erik showed, using the orange and red train as one, that the difference between the two fractions was one fourth. Alan used the purple rods (which were equivalent to thirds in that model) to show that three purple rods were larger than one dark green rod (one half) by “two fourths, one half, or six sixths.” Erik asked Alan why he was using thirds instead of fourths. Erik then explained his solution to the visitor. He labeled his rods and explained that three fourths was larger than one half by one fourth. The visitor asked Alan if he agreed, and he said that he did. After this discussion, Alan built a second model to show the difference between three fourths and one half, this time using the brown rod as one. Researcher Amy Martino then questioned Erik and Alan about their models, and Erik repeated his explanation. Alan then used his new model to directly justify his solution of one fourth. The researcher then noted that, although they had built different models, they had each arrived at the same solution. Alan stated that no matter what model you make it will always remain one fourth. He then used a model twice the length of his second model to show that the relationship held, and concluded that the difference between the two fractions would always be one fourth.
