Addition by type
| Type | What is on the sheet | Worksheet |
|---|---|---|
| Adding within 5 | Numbers 1 to 5 | LKG |
| Adding within 10 | Numbers 1 to 10 | Kindergarten |
| Adding within 20 | Numbers 1 to 20 | Grade 1 |
| 2-digit addition | Numbers to 100, carrying included | Grade 2 |
| 3-digit addition | Numbers to 1,000 | Grade 3 |
| 4-digit addition | Numbers to 10,000 | Grade 4 |
| Large-number addition | Numbers to 100,000 | Grade 5 |
The ranges above describe the numbers being added, so a total can land above them: grade 2 adds numbers under 100 and some answers pass 150. Problems are laid out horizontally, one per line with a blank for the answer, which suits fact fluency and timed drills rather than teaching the column algorithm.
How to use these worksheets
Pick the level your child is actually working at rather than their school year. A grade 2 student who still counts on fingers for sums within 20 will gain more from the grade 1 sheet than from a harder one they cannot finish.
Print the sheet, set a ten-minute timer, then check against the answer key on page 2. If more than three come out wrong, press New problems and repeat the same level tomorrow instead of moving up. Teachers can generate a second set for retakes so no two students hand in identical papers.
Frequently asked questions
Are these addition worksheets free to print?
Yes. Every sheet is free to print or save as a PDF, with the full answer key on page 2. No signup, no email, no watermark.
What grades do these addition worksheets cover?
LKG stays within 5 and kindergarten within 10. Grade 1 works to 20, grade 2 to 100, grade 3 to 1,000, grade 4 to 10,000, and grade 5 to 100,000.
Do the worksheets include carrying?
Yes, from grade 2 upward, where pairs like 67 plus 58 need carrying. LKG through grade 1 stay small so children can add without it.
Can I get a different set of problems on the same sheet?
Yes. Press the New problems button on any worksheet and a fresh set is generated instantly, answer key included, so you can print as many versions as you need.
