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

 

Using place value blocks to model addition is an excellent instructional strategy.  Most students can add.  The problem that I find with their addition is that they really don't understand what it means to regroup.  They can do it with paper and pencil, but have no concept of what it really means.  Using place value charts and blocks give them that conceptual undertanding.  By regrouping with the blocks, the students understand the concept of regrouping.
