If you need 5th grade decimals 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. A typical problem from the sheet in front of you is 40.51 + 35.47, which works out to 75.98; another is 62.38 − 42.25, giving 20.13.
‘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.
This sheet uses two-place decimals up to 49.95, with two decimal places, which is the form children meet most often in money and measurement — 92.42 − 86.82 is a fair example of it.
Writing in a trailing zero so both numbers have the same number of decimal places is not required mathematically and helps enormously in practice.
Adding decimals is column addition with one extra rule: the decimal points line up. Get that right and 40.51 + 35.47 is no harder than the whole-number version; get it wrong and the answer is not remotely 75.98.
Because the numbers regenerate, the alignment has to be handled fresh each time rather than copied from a previous layout.
In US classrooms these 5th grade decimals worksheets are commonly aligned with the decimal operations expectations for grade 5, though the exact wording varies from state to state.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 40.51 + 35.47 = | 75.98 | Watch for: losing the decimal point in the answer |
| 2 | 62.38 − 42.25 = | 20.13 | Check: lining the numbers up on the right |
| 3 | 2.8 × 9 = | 25.2 | Look at: regrouping across the decimal point incorrectly |
| 4 | 1.99 + 6.23 = | 8.22 | Ask about: forgetting the trailing zero |
| 5 | 92.42 − 86.82 = | 5.60 | Watch for: treating the two sides of the point as separate numbers |
| 6 | 8.4 × 4 = | 33.6 | Check: not estimating |
Here is one worked through. 62.38 − 42.25 gives 20.13. If your child arrives somewhere other than 20.13 on 62.38 − 42.25, look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.
A good first problem to do together is 40.51 + 35.47, which comes out at 75.98. Do 40.51 + 35.47 once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
Keys are produced by the same code that produces the questions, so a mismatch between question and answer is not possible on these sheets.
Answers appear next to their question numbers, so a wrong item like 62.38 − 42.25 can be found in the key in a second and re-worked while it is still fresh.
If the problems look cramped, drop the count from 20 to a smaller number before printing these 5th grade decimals worksheets; the font stays the same size and the spacing opens up.
Portrait orientation is what the sheet is designed for. Landscape works but wastes about a third of the paper, so leave the orientation alone unless you have a reason.
Keep the finished 5th grade decimals worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
