Addition Worksheet Generator
Print addition practice that matches exactly where your students are: sums within 10, two-digit problems with no carrying, columns that must carry, or three addends at a time. Each sheet has a name-and-date header and a separate answer key page. Free, no sign-up.
Quick levels
Missing-addend problems use the one-line layout and two addends.
Leave blank to use the default title.
The same number with the same settings always gives the same worksheet. Type one to bring a sheet back.
In the print dialog choose the paper size above, set the scale to 100%, and turn off headers and footers. The answer key starts on its own page, so print page 1 for students.

How to Use the Addition Worksheet Generator
- 1. Start from a quick level. Buttons set sensible defaults — Sums within 10, 2-digit, no regrouping, 3-digit and more. Everything stays editable afterwards.
- 2. Decide on regrouping. Allowed leaves it to chance, None guarantees that no column adds past 9, and Required makes every problem carry at least once.
- 3. Set the size and shape. Choose how many numbers to add, how many digits each has, an optional largest sum, and a stacked or one-line layout. Turn on Carry boxes to print small dotted boxes above the columns.
- 4. Print. New worksheet draws a fresh set; Print sends page 1 (the student sheet) and page 2 (the answer key) to the printer. Print page 1 only for students.
Regrouping Is the Skill This Sheet Isolates
Adding two-digit numbers is really two separate skills: adding within each place value, and regrouping — carrying ten ones into a ten — when a column adds past 9. Students often meet both at once, and a wrong answer can come from either. The None setting builds each column so its digits sum to 9 or less, which lets a student practise lining up and adding by place value with no carries. Switch to Required when that is secure, and every problem asks for at least one carry.
Worksheet 482913 — two-digit addition, five problems
Regrouping: none
21 + 15 = 36, 63 + 24 = 87, 60 + 12 = 72, 63 + 15 = 78, 62 + 26 = 88
Regrouping: required
52 + 59 = 111, 33 + 95 = 128, 24 + 16 = 40, 67 + 42 = 109, 22 + 84 = 106
In the first problem of the second set, 52 + 59, the ones column gives 2 + 9 = 11: write 1 and carry 1. The tens column then gives 5 + 5 + 1 = 11, so the sum is 111 — which is why that problem carries twice.
Levels by Skill
| Skill | Settings | What it builds |
|---|---|---|
| Number facts to 10 | Quick level: Sums within 10 | Automatic recall of small sums; zero is included |
| Single-digit facts | 1 digit and 1 digit, no limit | Sums up to 18, including facts that make a ten and then some |
| Two-digit, no carrying | 2 digits, regrouping None | Place value and column alignment |
| Two-digit, carrying | 2 digits, regrouping Required | Carrying ones into tens |
| Three-digit and beyond | 3 to 5 digits | Repeated carrying, including across several columns |
| Three or four addends | 3 or 4 numbers | Keeping a running total; larger carries |
Grade placement depends on your curriculum. In the Common Core State Standards, for example, students "add and subtract within 20" in grade 1 (1.OA.C.6) and are expected to know from memory all sums of two one-digit numbers by the end of grade 2 (2.OA.B.2). Adding and subtracting within 1000 appears in grade 3 (3.NBT.A.2), and grade 4 asks for the standard algorithm with multi-digit whole numbers (4.NBT.B.4). Use these as a rough map and check your own state or school standards.
Missing-Addend Problems and Seeds
With two addends and the one-line layout you can hide one addend instead of the sum: 6 + ? = 10. That is the bridge to subtraction, since finding the gap is the same as subtracting. The sheet's six-digit worksheet number lets you regenerate the same problems and answer key later; typing a number back in with the same settings restores the sheet. Everything runs in your browser and nothing is uploaded.
Frequently Asked Questions
- What is regrouping in addition?
- Regrouping, also called carrying, happens when the digits in a column add to 10 or more. Ten ones become one ten (or ten tens become one hundred), and that extra group is added to the next column. In 47 + 38, the ones add to 15, so you write 5 and carry 1 to the tens.
- How do I make addition worksheets without regrouping?
- Set Regrouping (carrying) to None. Every problem is then built column by column so that no column adds past 9 — 21 + 15 and 63 + 24 qualify, while 47 + 38 does not. This works for two, three or four addends and for up to five digits.
- Can I limit the sum, for example to 10 or 20?
- Yes. Use Largest sum, or the Sums within 10 quick level. If a limit contradicts another setting — say, one-digit problems that must carry yet total at most 9 — the sheet warns you that some problems break a rule, rather than quietly ignoring it.
- What are carry boxes?
- Small dotted boxes above the columns of each stacked problem, where students write the carried digit. They are a scaffold for students new to the algorithm and can be switched off once carrying is routine.
- How many problems fit on one page?
- At the default size, about 20 to 30 stacked two-digit problems or 12 to 20 with three or more digits. Adjust the number of problems and the problem size until page 1 holds the sheet; the preview shows it as it will print.
- Can I print the same worksheet again later?
- Yes. The worksheet number printed in the corner, with the same settings, brings back the identical problems and answer key. Changing any setting changes the problems.
