Q:

# How do you teach math regrouping in third grade?

A:

Base Ten Blocks provide students with a visual representation and physical manipulative to help facilitate understanding of regrouping. To teach regrouping using Base Ten Blocks, have students exchange ten units, which represent ones, for a single rod, which represents tens. Ten rods are exchanged for one flat, representing 100.

Base Ten Blocks is used to model regrouping in addition up to the thousands place value. By adding numbers that require regrouping, students will need to continually exchange smaller place value blocks for larger blocks. This process can be reversed to teach regrouping in subtraction.
