## Reflection: Developing a Conceptual Understanding Much Much More Than Take Away - Section 4: Summarizer

During the summarizer of this lesson, it was clear that students should begin the lesson with review of how we use addition to create a part/part/whole model.  While listening to the students' turn and talk discussions at the end of the lesson, I noticed that the students had a difficult time relating addition and subtraction, which will become a problem when asked to think about this relationship in the fact family lesson.
