Reflection: Real World Applications Grandma's Cookie Production Company - Section 4: Sharing and Closure


When students share their problem solving ideas  - the strategies, the models, and the thinking that went into their work – it is all done within the language and concepts of a 3rd grade child. The conversations and questioning from the others becomes real, in part, because it is explained through the thinking of a peer.

Making sense of division was the content purpose of today’s close, and so it was taught in a real-world context a child could relate to. How a student arrived at the understanding of division, as partition into equal shares, isn’t nearly as important as whether they got that idea.

Another purpose for my lesson close was that in listening to student thinking, I reflect on whether my lesson achieved its goal. I take that understanding into my teaching tomorrow.
