The activity is from a Shell Center task, and the student work is from my own class. We’re missing a few kids, but this is representative of the whole group’s work.

Questions:

  1. What do you notice? Anything interesting?
  2. What categories of student responses do you see?
  3. What sort of feedback would you give to push their mathematical thinking further?
