The worksheet generator on this page produces 6th grade decimals worksheets with real, freshly randomised numbers — 20 of them per sheet by default — plus the answer key a parent or teacher needs to mark it quickly. You will see items like 2.15 + 2.94 and 95.97 − 67.82 on the printed page, with 5.09 and 28.15 waiting on the answer key so nobody has to redo the arithmetic.
‘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.
Writing in a trailing zero so both numbers have the same number of decimal places is not required mathematically and helps enormously in practice.
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 — 4.53 + 24.90 is a fair example of it.
This is where place-value understanding gets tested. To a child who really understands 8.2 × 6.3, the tenths column is not 'the first column after the point' — it is a place worth a tenth.
Adding decimals is column addition with one extra rule: the decimal points line up. Get that right and 2.15 + 2.94 is no harder than the whole-number version; get it wrong and the answer is not remotely 5.09.
In US classrooms these 6th 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 | 2.15 + 2.94 = | 5.09 | Watch for: lining the numbers up on the right |
| 2 | 95.97 − 67.82 = | 28.15 | Check: forgetting the trailing zero |
| 3 | 8.2 × 6.3 = | 51.66 | Look at: treating the two sides of the point as separate numbers |
| 4 | 17.2 ÷ 4 = | 4.3 | Ask about: not estimating |
| 5 | 4.53 + 24.90 = | 29.43 | Watch for: losing the decimal point in the answer |
| 6 | 61.74 − 21.99 = | 39.75 | Check: regrouping across the decimal point incorrectly |
A good first problem to do together is 2.15 + 2.94, which comes out at 5.09. Do 2.15 + 2.94 once with the child narrating, then hand over the pencil and start the clock on the other 20 problems.
The item 95.97 − 67.82 is worth doing slowly. The answer to 95.97 − 67.82 is 28.15, and the route to it is the route every other problem on this sheet takes — which is why the sheet has 20 of them rather than one.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 2.15 + 2.94 is listed as 5.09, 95.97 − 67.82 as 28.15, and so on down the page.
Answers appear next to their question numbers, so a wrong item like 95.97 − 67.82 can be found in the key in a second and re-worked while it is still fresh.
The sheet is laid out to fit one page on both US Letter and A4. Leave the browser scaling at 100% and turn headers and footers off, and the 20 problems land inside the margins on either paper size.
Printing works the same on US Letter and A4, because the layout uses relative widths rather than fixed inches. Set margins to default and scaling to 100%, and all 20 problems fit.
When these become easy, move along the related links below rather than adding more problems to the same sheet.
