What's included in this worksheet
Each worksheet is a single US Letter page (A4-friendly) of addition problems drawn from your chosen number range, with a second page giving every sum as the answer key. A 1–10 range is single-digit practice; widen it to 1–20 or beyond for two-digit sums and regrouping. Because each sheet is generated deterministically from its settings, the same options always print the same problems.
One generator, six different addition worksheets — pick the problem type that matches what your child is working on:
- Basic addition facts — Mixed addition facts drawn from the number range you choose — the default sheet, stacked the way addition is taught on paper.
- 2-digit with regrouping — Every problem carries: the ones digits always add to 10 or more, so each one practises regrouping rather than only occasionally hitting it.
- 2-digit without regrouping — Two-digit addition where no column ever adds past 9 — no carrying at all, which is the step to master before regrouping.
- 3-digit addition — Three-digit numbers in column form, with carries falling wherever they naturally land — the sheet for consolidating the standard algorithm.
- Missing addend — The total is given and one addend is blank (8 + ▢ = 15) — the bridge from adding to subtracting, and a staple of first-grade fluency work.
- Column addition (3 numbers) — Three two-digit numbers stacked in one column — adding a third row is where children have to hold a running total, not just one pair.
Tips for practicing addition
- Begin with a 1–10 range so every sum stays under 20 — the sums-to-ten facts are the foundation for everything after.
- Move to a 1–20 range to introduce carrying (regrouping) once single-digit sums are automatic.
- The vertical layout mirrors how addition is written in class — great for practicing lining up columns neatly.
- Use the answer key for quick self-checking; finding their own mistakes builds number sense.
- Short daily sheets beat one long session — five focused minutes a day is plenty for young learners.
Customization options
Problem type
Basic facts come first, then 2-digit addition with and without regrouping, then 3-digit. The with-regrouping type makes every single problem carry, rather than leaving it to chance, so a whole sheet is regrouping practice. Missing addend and column addition round it out. Each type generates a genuinely different sheet with its own answer key.
Number range
The range sets both addends. Keep it at 1 to 10 for single-digit facts, or raise it to 1 to 20 (or higher) to practice two-digit addition and carrying.
Number of problems
Put anywhere from 4 to 40 problems on a page. Fewer, larger problems suit beginners; a full sheet works well as a timed fluency drill.
Layout
Choose a horizontal row of equations, a boxed grid, or the stacked vertical format that mirrors how the operation is written on paper. Some problem types set their own layout — long division always uses the division bracket, and fact families always use the family box — because those can't be written correctly on a single line. The preview and the downloaded PDF always match your choice.
Frequently asked questions
What grade are these addition worksheets for?
The default 1–20 range suits kindergarten through 2nd grade. For the youngest learners, narrow it to 1–10 for single-digit sums; raise the upper number to practice two-digit addition with regrouping.
Do the addition worksheets include an answer key?
Yes. Every download is a two-page PDF — the worksheet first, then a complete answer key with every sum filled in. The answer key is always free and never gated.
Can I make single-digit-only addition sheets?
Yes. Set the largest number to 9 (or lower) and every addend stays a single digit, so all the problems use the basic addition facts.
Why is the vertical (stacked) layout the default?
Stacked column format is how addition is written and taught on paper — it gives children practice lining up columns and carrying. You can switch to a horizontal or boxed layout anytime in the options.
Will the same settings always give the same worksheet?
Yes. Problems are generated deterministically from your options, so the same settings always produce the same sheet and answer key — handy for reprinting or handing an identical sheet to a class.
Is this addition worksheet generator free?
Completely free — no signup, no email, no watermark, and no limit on the number of worksheets or copies you make and download.
What paper size do the worksheets print on?
US Letter (8.5 × 11 inches) by default, and they print cleanly on A4 too. Print at 100% scale for correctly sized problems.
Do you have addition worksheets with regrouping?
Yes — choose the “2-digit with regrouping” problem type. Every problem on that sheet is built so the ones digits add to 10 or more, which means each one needs a carry. There is a matching “without regrouping” type for the step before it.
What is a missing addend worksheet?
It gives the total and one addend, leaving the other blank: 8 + ▢ = 15. It is the bridge from adding to subtracting, and a standard part of first-grade fluency work. Pick the “Missing addend” problem type.
Can I make column addition worksheets with three numbers?
Yes. The “Column addition” problem type stacks three two-digit numbers in a single column. Adding a third row is where children have to hold a running total rather than just one pair, so it is a real step up from two-addend sheets.
