Now let's watch a video excerpt (duration 9:02) of Dot Doyle's 11th- and 12th-grade class working on this problem.


As you watch the video, keep these questions in mind:

  • What evidence is there that the students understood the use of a tree diagram for this problem?
  • When did the teacher decide to introduce the idea of switching from a tree diagram to matrices? Why?
  • What specifically did the students understand about the matrix representation, and how did the teacher elicit such information?
  • How does the class organization and structure support an exploration of representation? Give examples to support your answer.
  • How could the teacher extend the problem?
