Addition Worksheet Generator

Generate printable addition worksheets with fresh random problems at four difficulty levels, from single digits to 4-digit numbers.

Pick a difficulty and problem count, and the generator builds a brand-new sheet every time — no two worksheets are alike. An optional answer key fills in the sums on screen, so you can print a student copy and a teacher copy of the exact same sheet.

Tip: turn on the answer key before printing to print a teacher copy with answers filled in.

How to use this calculator

  1. Choose a difficulty level, from 1-digit up to 4-digit numbers.
  2. Choose how many problems to put on the sheet (12 to 40).
  3. Click New Sheet whenever you want a fresh set of problems.
  4. Tick "Answer key" if you want the answers printed on the sheet.
  5. Click Print; the sheet prints black on white.

The formula

Each problem adds two whole numbers, a + b. Answers are exact sums — for example 47 + 58 = 105.

Worked example

On the 2-digit setting, a typical problem is 47 + 58, and the answer key shows 105. A 20-problem sheet at this level mixes pairs from 10-99, including both carrying and non-carrying sums.

Frequently Asked Questions

How do I print the answer key?

Tick the "Answer key" box before printing. The answers appear on the same sheet in the same positions, so the student copy and teacher copy match problem for problem. Untick it to print the blank student version.

Are the worksheets really different every time?

Yes. Problems are drawn randomly for the level you pick, and the New Sheet button generates a fresh set. You can print a different sheet for every student in a class, which makes copying pointless.

Which level should my child use?

1-digit is for kindergarten and grade 1, 2-digit for grades 2-3 once regrouping (carrying) is introduced, 3-digit for grades 3-4, and 4-digit for grade 4 and up or for adults who want mental-math practice.

Does the 2-digit level include carrying problems?

It includes the full range of pairs from 10 to 99, so many problems require carrying and many do not — a natural mix, just like a textbook exercise set.

Can I use these in my classroom?

Classroom, homework, tutoring, and homeschool use is free and unlimited. Please do not resell the generated sheets as your own product.
