4 Digit by 1 Digit Multiplication Worksheets

These 4 digit by 1 digit multiplication worksheets are generated rather than scanned, which means you can print a different sheet every day of the week without paying for a subscription or running out of practice. A typical problem from the sheet in front of you is 6,268 × 3, which works out to 18,804; another is 9,894 × 9, giving 89,046.

📄 4 DIGIT BY 1 DIGIT MULTIPLICATION — A NEW SHEET EVERY TIME YOU PRESS THE BUTTON
🎲 New set of problems

‘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 you are practising here

The place-value zero in the second row is where most multi-digit errors live. Children who write it deliberately, rather than as a remembered squiggle, make far fewer mistakes.

Written multiplication is where the times tables get cashed in. In a problem like 6,268 × 3, the layout is simple and the arithmetic is not — every partial product depends on a fact being recalled instantly, and the answer 18,804 is only as reliable as the weakest of them.

Estimating before calculating changes the error rate more than any other single habit. Rounding the numbers in 9,894 × 9 first gives a range that 89,046 must fall inside.

Every sheet is regenerated, so the child practises the method rather than a particular set of partial products.

These 4 digit by 1 digit multiplication worksheets are commonly aligned with the multi-digit multiplication expectations for this grade, and the skill appears in most curricula somewhere around this point.

Six problems from the sheet in front of you

These six come from the sheet loaded on this page. Press the button and the numbers change, but the shape stays the same (a four-digit number times a one-digit number).
#ProblemAnswerWhat to check
16,268 × 3 =18,804Watch for: carrying into the wrong column
29,894 × 9 =89,046Check: adding the carry before multiplying
38,131 × 3 =24,393Look at: forgetting to add the partial products
47,089 × 5 =35,445Ask about: omitting the place-holding zero
56,410 × 3 =19,230Watch for: not estimating
63,578 × 9 =32,202Check: a shaky fact inside a correct method

Try one together first

Try 8,131 × 3 together before letting the child start alone. The answer to 8,131 × 3 is 24,393, and talking through how it was reached takes about a minute and saves several minutes of guessing later in the sheet.

The item 9,894 × 9 is worth doing slowly. The answer to 9,894 × 9 is 89,046, 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.

Three common mistakes and what to do about them

A 10-minute routine that works

  1. Stop the session at the time limit even if the sheet is unfinished, and note where the child got to. A half sheet done well is better data than a whole sheet rushed.
  2. Use a pencil, not a pen. Children working on four-digit times one-digit multiplication rethink far more often when erasing is allowed, and you get to see exactly where the rethinking happened on an item like 8,131 × 3.
  3. Run the sheet at the same time each day. Ten focused minutes before dinner beats an hour on Sunday, because four-digit times one-digit multiplication is a recall skill: 6,268 × 3 has to arrive without being worked out, and recall is built by frequency.
  4. Mark it together straight away while the working is still fresh, so a slip like the one behind 8,131 × 3 can be talked through instead of guessed at.
  5. Keep the session to about 10 minutes. A child working at this level who is still counting on fingers will need longer than that on a line like 6,268 × 3, and that is fine: the timer is a measurement, never a punishment.

Marking the sheet

Keys are produced by the same code that produces the questions, so a mismatch between question and answer is not possible on these sheets.

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.

Printing and saving as PDF

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.

If the problems look cramped, drop the count from 20 to a smaller number before printing these 4 digit by 1 digit multiplication worksheets; the font stays the same size and the spacing opens up.

Frequently asked questions

Is the answer key included?
Yes, on its own page behind the worksheet. For the sheet loaded right now it shows 18,804 for 6,268 × 3 and 89,046 for 9,894 × 9.
My child knows their tables but still gets these wrong. Why?
Almost always the layout: a missing place-holding zero, or a carry in the wrong column. Look at the partial products rather than the final answer to see which.
How many different sheets can I make?
As many as you want. The numbers are randomised each time, so printing five sheets in a row gives five different sets of 20 problems on the same skill.
How many multiplication problems a day is sensible?
Ten to twenty for written multiplication. It is slower per problem than fact practice, so 10 minutes gets you fewer items and that is fine.

One sheet of 4 digit by 1 digit multiplication worksheets a day for two weeks will tell you more about where a child working at this level actually stands than any single long assessment.
