Focus Questions
For use in a classroom, pause the video and ask this question:
[Pause the video at 2:07] What thoughts do you have about the graph that Claire and Mary created? What do you notice about the graph or its shape? What are you still wondering about regarding a graph of the relationship between height and angle of rotation?
Supporting Dialogue
As you watch Mary and Claire add additional points to their graph, consider this claim made by another student: “When you find a height for this graph, you can go ahead and cut another pipe cleaner to the same height because there’s another radian measure that has that same height.” What do you think of this claim? How many more pipe cleaners should you cut? Where would they go in relation to the one you first find?
