If you need 4 digit addition worksheets that you can print right now, this page builds them for you — 20 fresh problems, an answer key underneath, and no account to create first. The version loaded below opens with items in the shape of 2,362 + 5,596 and 3,570 + 5,677; the key lists 7,958 and 9,247 next to their question numbers.
‘New set of problems’ opens the generator in its own tab. There you can change the problem count and turn the answer key on or off. ‘Print or save as PDF’ opens the print dialog — choose Save as PDF in the printer list to keep the file. The sheet fits US Letter and A4, and the answer key prints on its own page.
What separates a confident adder from a slow one is rarely the method; it is whether the number bonds underneath are automatic. Watch how long the child hesitates before writing the first digit of 9,247.
The problems here use four-digit numbers up to 9,999, which keeps the arithmetic honest without turning the page into a copying exercise. 2,362 + 5,596 and 3,570 + 5,677 are typical of the range.
Addition is the first place a child meets the idea of a carried digit, and it is the skill every later algorithm leans on. A sheet like 2,362 + 5,596 looks small, but the habit it builds — line up the places, work right to left, record the carry — is the same habit that survives into multi-digit multiplication.
Written addition is worth practising in columns — which is what these 4 digit addition worksheets ask for — even when a child working at this level can do it mentally, because the column layout is what makes four-digit work manageable later. A problem such as 2,938 + 5,693 is small enough to do mentally and worth writing out anyway.
In US classrooms these 4 digit addition worksheets are commonly aligned with the addition strand of most US state standards for this grade, though the exact wording varies from state to state.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 2,362 + 5,596 = | 7,958 | Watch for: treating a longer number as a bigger one |
| 2 | 3,570 + 5,677 = | 9,247 | Check: counting on from the wrong number |
| 3 | 8,483 + 1,371 = | 9,854 | Look at: losing the place columns |
| 4 | 2,938 + 5,693 = | 8,631 | Ask about: guessing on the near-tens |
| 5 | 6,680 + 2,597 = | 9,277 | Watch for: adding right to left, then reading left to right |
| 6 | 1,561 + 1,253 = | 2,814 | Check: forgetting the carried digit |
Take the first problem on the sheet as it stands, 2,362 + 5,596. Work 2,362 + 5,596 out on paper rather than in your head the first few times, say each step aloud, and check the result against 7,958 on the key before moving on.
Here is one worked through. 3,570 + 5,677 gives 9,247. If your child arrives somewhere other than 9,247 on 3,570 + 5,677, look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.
Answers appear next to their question numbers, so a wrong item like 3,570 + 5,677 can be found in the key in a second and re-worked while it is still fresh.
Every generated sheet carries its own key on a separate printed page, which lets a child self-mark without seeing the answers while they work.
If the problems look cramped, drop the count from 20 to a smaller number before printing these 4 digit addition worksheets; the font stays the same size and the spacing opens up.
For a class set, print one sheet, press the new-worksheet button and print again. Each child gets different numbers on the same skill, so nobody can copy the answer to 2,362 + 5,596 from a neighbour.
Keep the finished 4 digit addition worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
