This free addition worksheet tool makes printable addition sheets in your web browser. You choose how many digits each number has, whether the sums need carrying, and how many problems to include, and the sheet updates as you go. Nothing is uploaded, and you do not need an account or sign-up. Use it for single digit addition worksheets for a young child, 2 digit addition worksheets for practice at home, or 3 digit addition worksheets with regrouping for older pupils. Teachers can use the same settings to make a math addition worksheet for a warm-up, homework, or a quiz. Every answer is worked out twice before it appears, and the answer key prints on its own page.

How to use the addition worksheet tool

Set Digits in the first number to 1, 2, 3, 4 or 5. The default is 2.
Set Digits in the second number the same way. Using different lengths, such as 5 and 3, mixes up the place values.
Set Carrying to Any, Every problem needs it, or None needed.
Choose the number of Problems: 10, 12, 15, 20, 24, 30 or 40. The default is 20.
Choose the number of Columns (2 to 6) and a Layout. Stacked is the usual written method. Across shows problems in a line with a blank to fill in.
Change the Title on the sheet if you want something other than “Addition”.
Leave Include answer key ticked to print the key on its own page, or untick it to leave the key off.
Check the preview, which updates as soon as you change a setting. Press New worksheet for different problems with the same settings. Each sheet shows a short worksheet code under the buttons.
Press Print or save as PDF. Paper size can be set to US Letter or A4. The browser’s print dialog can also save a PDF.

The page address stores your settings, so a bookmarked or shared link opens the same sheet again. Press Reset settings to return to the defaults.

What is carrying (regrouping) in addition?

Carrying, also called regrouping, is the step you take when the digits in one column add up to ten or more. You write only the ones digit of that total in the column, and carry the tens digit as a 1 into the next column to the left. For 47 + 38, the ones add to 15, so you write 5 and carry 1. The tens column then becomes 4 + 3 + 1 = 8, giving 85.

Carrying is why some sheets are harder than they look. Each carry adds an extra step that a child must remember, and each column depends on the one to its right. Teach it from the right-hand column first, because every carry feeds into the column on its left. A child who understands that a carried 1 means one ten (or one hundred) moving to the next column is less likely to treat it as a random mark.

How do I make addition worksheets with no carrying?

Set Carrying to None needed. The tool then checks each column, so every column total is under ten, and no sum needs a carry. A problem such as 47 + 38 will not appear on the sheet.

With no carrying, each column is a single addition fact, and the child adds the columns one at a time without any extra step. This makes the sheet a good way to build confidence with the written layout before adding carrying. Begin with a short sheet of about ten problems, then increase the number of problems and digits as the child becomes accurate. Move to carrying only when the no-carrying sheets are easy for them.

Why do numbers of different lengths cause mistakes?

With numbers of different lengths, such as 3,406 + 52, some children line the digits up from the left and put the 5 under the 3. The stacked layout lines the numbers up by place value, ones under ones. To practice the habit, choose a different number of digits for the two numbers and the Across layout, then ask children to copy each problem into columns on their own paper.

Questions teachers and parents ask

Which addition worksheets suit kindergarten and first grade?

For kindergarten and first grade, set both digit counts to 1 and Carrying to None needed. For sums within 20, keep 1 digit + 1 digit and set Carrying to Any so the sheet includes sums that cross ten.

How do I make 2-digit addition worksheets with regrouping?

Keep both digit counts at 2, the default, and set **Carrying** to Every problem needs it. Every sum on the sheet will then need a carry. For second grade, print a no-carrying sheet first, then move to the every-problem setting once that sheet is easy.

Are the answers checked?

Yes. Each sum is worked out twice: once with ordinary arithmetic and once column by column, the way a child works it on paper. A problem is used only when both methods agree, and no problem appears twice on the same sheet.

What does a wrong answer usually mean?

Look at the column where the mistake starts. Mistakes in the ones column are usually fact errors, so more practice with single-digit facts will help. Mistakes in the tens or hundreds column are usually forgotten carries. For example, 47 + 38 written as 715 means the 15 was written down whole instead of writing 5 and carrying 1. Ask the child to write the carried 1 above the next column every time.

Why use numbers with different lengths?

Set the two digit counts to different values, such as 3 digits and 2 digits, to make children line up the numbers by place value rather than from the left. A child may put the 5 of 52 under the 3 of 3,406. The stacked layout lines numbers up correctly, so ask the child to copy an across problem into columns to practice this habit.
