I learned so much from teaching this lesson and even more from listening to my colleagues and by continuing to dissect the student responses myself. Admittedly, my first look at the student work was a bit devastating. However, I now see that we launched something much larger than a model (bar model) for division story problems. The students in the classroom are primed for active and thoughtful metacognition about their own math understanding. I truly believe that their continued experiences trouble-shooting math models, strategies, and connections will weave a strong foundation of vital math understandings which serve them well as they venture into more abstract mathematics such as formal algebra.
