Addition with Regrouping
Work with your child to help him or her understand the concept of regrouping when adding numbers. The illustrated example below can be used to help explain this. Also, activities with money, such as adding cents and then exchanging groups of ten for dimes will also help master the concept of regrouping.
We use the base ten number system to write numbers with each place having a value; ones, tens, hundreds, thousands, and so on.
When we add numbers we often have to combine these groups if we end up with more than 9 in any one group. Below is an example of addition with regrouping.

| Start by adding the ones. We have 12 ones but only one place! | We must regroup our 12 ones to give 1 ten and 2 ones | Now we can put the 1 ten with the tens and write 2 in the ones place | Finish by adding the tens including
the 1 ten that was regrouped 2 + 3 + 1 = 6 |
