My coach gave great suggestions. The first suggestion was that the deadline for completing this activity was quickly approaching and that I needed to act on it. I always appreciate reminders so I did as I was told. :) Later, the second suggestion was adding visuals to the frame routine which I could have added on with the students' discussion or embed in the pre-printed frame to help generate discussion. We choose the latter deciding that some of our students would appreciate not having to draw two number lines in that little space. Suzanne Graham has been very accessible by email and always responds quickly.
