Reflection: Developing a Conceptual Understanding Subtracting Whole Numbers - Section 5: Closure


Having the students use place value charts and blocks to subtract really was a good strategy to give the students a visual understanding of the skill.  Some of the students had a hard time regrouping.  By practicing over and over, the students finally understood how modeling on the place value chart coincides with using subtracting with paper and pencil.  Subtraction is a skill that the students begin in lower grades.  A lot of the students know how to do the algorithm, but have no concept of actually what it means to regroup.
