Adding With Regrouping. When we make a new ten from the ones, we are regrouping. Way back when I learned this stuff, it was called "carrying." Guide students to use base ten blocks to solve two-digit by one-digit addition problems with regrouping.
The ten ones get grouped as a ten, and are counted with the other tens. This video demonstrates addition of two digit. First, add the ones: This is called "regrouping" since we had to put the tens guy in the next stripe over with all the other tens guys!
Students identify, use, and share strategies for adding three-digit numbers that require regrouping.
Connect coding to any subject and encourage students of all levels to discover computer programming!
You can create printable tests and worksheets from these Addition with Regrouping questions! This video is a fun rap to help you remember the steps for adding with regrouping. Addition with regrouping is a very systematic concept for students to learn and without a solid understanding of place value, there's no point in going any further with instruction.
