Regrouping

Yes, the time has come. We are reviewing addition with regrouping. Although it may feel like torture to some children, they are doing quite well. We are even venturing into regrouping with 3 digit numbers...

As you are working with your children, remember that math instruction has changed since we were in elementary school. You probably know regrouping as carrying.
"5 + 9 = 14. Put down the 4, carry the 1..." Children can still solve addition problems this way. The only thing different for that method, is that we call it regrouping. They don't carry the one, they regroup the 10 (or the hundred).

There are two major challenges with regrouping. First, it's important that children have lined up the numbers properly. The digits in the hundreds place, tens place and ones place need to be lined up. It's not accurate to combine 3 from the ones place with 4 from the tens place. Also, children tend to forget that the little 1 they are "regrouping" is really a ten. It's important for them to remember that so they can develop a sense of the numbers.

As always, don't hesitate to contact me with any questions, comments or concerns.
