By the end of the third grade, students should be fluent with addition within 1000. Students already had considerable practice of addition within 1000 in the second grade. But as fluency is an expectation in third grade, students must be exposed to a variety of methods, including the standard algorithm for addition. In this worksheet, students add 3 digit numbers to 3 digit numbers with situations involving regrouping (carry).

Common Core Alignment

3.NBT.2Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.

We can do addition by writing one number below the other
and then add one column at a time, like this:

(Practice on this Simple Column Addition Worksheets)

And it works for bigger numbers, too:

But sometimes two-digit numbers can get in the way like this:

THIS is how it should be done:

Did you see how we split the 12 into 1 Ten and 2 Ones?

We then sent the 1 Ten to the top of the Tens column, so we will remember to add it when we do the Tens.

And there is a nice clear space for the Tens answer below.

Here's another example:

Now practice on this Column Addition (with Carrying) Worksheets.

Above or Below?

Your teacher may want you to put the "1" below like in this example.

Above or below does not really matter, we just need a good place to put the "1" so we don't forget it!

What About Bigger Numbers?

The same method works with numbers in the hundreds, thousands and so on.

But we must be careful to move over one column each time.

Like this:

Add a 3 digit number to another 3 digit number without regrouping. In this grade, adding by using the standard algorithm should not be the focus. Students should practice addition based on concepts of place value. For example, to add a 3 digit number to another 3 digit number, they can add hundreds to hundreds, tens to tens and ones to ones. To understand how this works, they should look at the expanded forms of numbers. For example, 323 + 145 is the same as (300 + 20 + 3) + (100 + 40 + 5). They can now group the hundreds, tens and ones together to add. It is important for students to know how a particular method works, rather than just using the method. Adding using place concepts value concepts will help the students make sense of the standard algorithm, when they use it more and more in the higher grades.

Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
