Reflection: Student Led Inquiry Using Area Model to Divide Thousands - Section 3: Concept Development


In the video below two students use different numbers to complete the same division problem while applying the rectangular sections method. In the end, each arrives at the same quotient. As I observed them work and as I watch the video, I am really pleased by the students' willingness to work with different numbers. It shows flexibility and number sense. As discussed in my warmup narrative, the use of comfortable or friendly numbers should enable each student to focus more of their cognitive attention on understanding the problem.
