The worksheet generator on this page produces 4th grade 3 digit by 1 digit multiplication 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 760 × 2 and 528 × 2 on the printed page, with 1,520 and 1,056 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.
Estimating before calculating changes the error rate more than any other single habit. Rounding the numbers in 528 × 2 first gives a range that 1,056 must fall inside.
If a child can do the layout but keeps getting the arithmetic wrong, the problem is table fluency rather than multiplication, and the times table pages linked below fix that faster than more lines like 930 × 7 will.
This sheet uses a three-digit number times a one-digit number, which is large enough to need the full written method and small enough to check by estimation, as the item 930 × 7 on this sheet shows.
Every sheet is regenerated, so the child practises the method rather than a particular set of partial products.
Teachers usually place 4th grade 3 digit by 1 digit multiplication worksheets alongside the multi-digit multiplication expectations for this grade, which is where the skill sits in the majority of US state frameworks.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | 760 × 2 = | 1,520 | Watch for: omitting the place-holding zero |
| 2 | 528 × 2 = | 1,056 | Check: not estimating |
| 3 | 364 × 6 = | 2,184 | Look at: forgetting to add the partial products |
| 4 | 649 × 7 = | 4,543 | Ask about: adding the carry before multiplying |
| 5 | 930 × 7 = | 6,510 | Watch for: carrying into the wrong column |
| 6 | 825 × 9 = | 7,425 | Check: a shaky fact inside a correct method |
Work 649 × 7 out loud as a demonstration. It gives 4,543. Children who hear 649 × 7 reasoned through once at the start of a session make noticeably fewer errors in the ten minutes that follow.
Here is one worked through. 528 × 2 gives 1,056. If your child arrives somewhere other than 1,056 on 528 × 2, look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — 760 × 2 is listed as 1,520, 528 × 2 as 1,056, and so on down the page.
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.
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.
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.
