Regrouping is one of those skills that just takes time and practice to get good at. It comes down to understanding the concept of place value and how in the base ten system you can regroup between those place values. This series of worksheets and lessons below will help you with a more complex carrying and regrouping model for you. You will see a value advance over two or three places. This is very similar to the ones to tens model. Just focus on staying organized and this skill should come to you quickly. The top sheets will have a grid to work with the sheets on the bottom of the page remove the grid and go full old school on this topic.

Skill Introduction Lesson
This is a 3 step process. Step 1: Add all the digits in the ones column. (First add the numbers that make a ten.) Step 2: Add all the digits in the tens column. Step 3: Add all the digits in the hundreds column.
Try the Skill
Add in columns. You add the addends and regouping between the place values. Write the hundreds, tens, and ones in the correct column. Write all the numbers having hundreds place value under hundreds column, numbers having tens place value under tens column, numbers having ones place value under ones column. Add them.
Practice Regrouping Worksheet
Add 4 integers in a vertical column. This is a true step up. Keep yourself well spaced out and write clearer so you can keep up with where you go as you move forward.

Show the Skill
A nice follow up for you on this skill. It isn't the easiest one to master right away. The hundreds column gets a real workout here. The tens column has a great deal of activity and requires your focus. Concentrate on those two areas and you will be successful.

What is Regrouping in Math?
We you hear the word regroup; you may feel that a total rearrangement is required to make any significant changes. In terms of addition it usually means we moving a value for one place value to another. For instance, if you were adding 27 and 5. When we look at the ones column, we get a value of 12. This means that we an additional value that needs to be part of the tens place. We would therefore regroup this value to be 32. The tens value gets placed in tens place and the one value stays flat. This can get more complicated as you advance to double, triple, and even quadruple digit values. But, the core principle remains, find the place value that is overcrowded and push it up to the next place value. You will find six printable worksheets as you scroll down. Each successive worksheet adds a new detail that will make your day a bit easier to handle. We would definitely suggest that you take a look at the Try the Skill worksheet.

What is Addition with Regrouping?
Math is one of the most common subjects with which children often have problems. Depending more on formulas and equations, math requires a complex, problem-solving approach that can be tough for children to pick up. However, every problem has certain tricks that, once mastered, will make any problem easy.
Addition with, regrouping is a method used in math to add two or more numbers together. In this method, the number that needs to be added are arranged in groups of ten, usually done when the numbers are in double digits or if the answer is larger than ten. The column place values exceed one, ten, hundred, and so on.
Regrouping is also referred to as “carrying over.” We place the two or more numbers in a column according to their place values and add them. If the sum of the numbers exceeds ten, then the number is carried over to the next value column.
Example 1: The sum would be thirteen when adding six and seven. So, we will write the three in one column while the one is carried over to the ten’s column.
Example 2: When adding double-digit numbers such as 28 and 14: place the numbers in their correct column value. Add the values 8 and 4 together, getting 12. The two is placed under the one’s column, and the one is carried over to the ten’s column. Now we will add 2 and 1, getting 3, but since one was carried over, we will add 2, 1, and 1 together, getting 4. The answer will then be 42.
When to Use It
Regrouping is used when the sum of the values in the one’s column is greater than nine. However, if the sum falls below nine, you do not need to use the regrouping methods. This is because no numbers are required in order to be carried over.
Example: When adding 11 and 16, the sum of 1 and 6 in the one’s column would be 7, while the sum in the ten’s column is 2. Nothing needs to be carried over so it can be done visually.
How to Teach It
The regrouping method is simple, and most children quickly pick up on it. One thing to ensure is that the child is conceptually clear on the place values of the column. Children should be aware of the division of the column into ones, tens, hundreds, thousands, etc., going left of the column.
The best way for you to teach addition with regrouping is with examples. There is only so much a child will learn with only audio lessons, requiring visual aid to speed up the progress. Solve a few questions in front of them, then solve a few with them.
Children must also know simple addition. This can be done by the finger counting method or the line drawing method. If they know how to add two single-digit numbers together, they will soon learn addition with regrouping.
To Sum Up
Practice is one of the most important things in learning addition with regrouping. Regularly give out worksheets and practice questions for the children to work on. Practice makes perfect!
