At the beginning of every new school year, I go through a mourning period. It usually hits me at the end of the first week of school. This year is no different. I asked my fifth graders, "What do you think?" And I looked out at a sea of blank stares. Crickets. I even tried applying the old-uncomfortable-silence-during-wait-time trick. I stood silently and waited for someone to say something. Usually, it works because people become so annoyed by the silence that they'll say something just to break it. Again, crickets.
Outwardly, I smiled brightly, the picture of virtuous patience, but on the inside, my brain moaned and groaned, "I miss my kids...my kids from last year who couldn't wait to think and talk." It was time to break out my thinker's tool box. I needed my visible thinking routines. They had become so automatic in previous years, but the summer was long, and I was as rusty as my students. The next day, we began again.
The Problem
We had been working with the concept of area. The focus of our lesson was that the area of a rectangle could be represented by square inches and square feet. Students were working with grid models of area using mixed and whole numbers. They were struggling to understand that the area of the picture in front of them could be measured in two different ways.
Allison and Justin were laying tile in their bathroom floor. Allison said they needed 5 square feet in tile. Justin disagreed and said they needed 20 square feet. Who is correct?
They presented passionately. At the end of the debate, most students moved their sticky notes to the Allison side of the tug-of-war line. Here's what was cool about this:
1. There was no crying or sense of failure because the Justin team could explain their error in thinking, and the Allison team could completely understand how that happened.
2. Students practiced the secondary goal of the math lesson: To practice mathematical discourse. It was remarkable to hear "I disagree...because..." and "Can you tell me more about that?"
3. Every single student was engaged. I'm serious. I had one of those tingly teacher moments when I watched them debate. No one was idle. Not one student.
4. When we were done, I asked students how their understanding had changed. Every one of them was able to identify how they had changed. It was a fabulous day for exit tickets!
