This page makes free printable 4th grade math word problems worksheets on demand: press the button and you get a new sheet of 20 problems with a matching answer key, ready for US Letter or A4 paper. The version loaded below opens with items in the shape of “Each row at the sports hall has 3 chairs. There are 9 rows. How many chairs?” and “A rope 15 cm long is cut into 3 equal pieces. How long is each piece?”; the key lists 27 and 5 cm 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.
Answers should carry their units. A number without a unit is not an answer to a word problem, however correct the arithmetic.
Key words help and mislead in roughly equal measure. 'Altogether' usually means add and sometimes does not, so the child still has to picture the situation.
These problems use products under 290, so the reading, not the arithmetic, is the challenge.
The reliable routine is to read it twice, say what is being asked in your own words, write the number sentence, then calculate. Skipping straight to the numbers is what produces confident wrong answers.
In US classrooms these 4th grade math word problems worksheets are commonly aligned with the problem-solving expectations for this grade, though the exact wording varies from state to state.
| # | Problem | Answer | What to check |
|---|---|---|---|
| 1 | Each row at the sports hall has 3 chairs. There are 9 rows. How many chairs? | 27 | Watch for: answering a different question |
| 2 | A rope 15 cm long is cut into 3 equal pieces. How long is each piece? | 5 cm | Check: dropping the units |
| 3 | Cleo saves 16 dollars a week for 3 weeks and then spends 8 dollars. How much is left? | 40 dollars | Look at: being thrown by unfamiliar names or objects |
| 4 | Ruby packs 3 crayons into each bag and fills 11 bags. How many crayons in all? | 33 | Ask about: grabbing the numbers and guessing the operation |
| 5 | 60 books are packed 6 to a box. How many boxes are needed? | 10 | Watch for: not checking whether the answer is sensible |
| 6 | Omar buys 5 packs of 3 pencils and then loses 20. How many pencils are left? | -5 | Check: missing a step in a two-step problem |
Here is one worked through. “A rope 15 cm long is cut into 3 equal pieces. How long is each piece?” gives 5 cm. If your child arrives somewhere other than 5 cm on “A rope 15 cm long is cut into 3 equal pieces. How long is each piece?”, look at the working rather than the answer: nearly every wrong result comes from a skipped step, not an unknown fact.
Take the first problem on the sheet as it stands, “Each row at the sports hall has 3 chairs. There are 9 rows. How many chairs?”. Work “Each row at the sports hall has 3 chairs. There are 9 rows. How many chairs?” out on paper rather than in your head the first few times, say each step aloud, and check the result against 27 on the key before moving on.
The answer key is generated with the worksheet, not written by hand, so it always matches the sheet in front of you — “Each row at the sports hall has 3 chairs. There are 9 rows. How many chairs?” is listed as 27, “A rope 15 cm long is cut into 3 equal pieces. How long is each piece?” as 5 cm, and so on down the page.
Answers appear next to their question numbers, so a wrong item like “A rope 15 cm long is cut into 3 equal pieces. How long is each piece?” 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 4th grade math word problems worksheets; the font stays the same size and the spacing opens up.
To save these 4th grade math word problems worksheets instead of printing them, choose 'Save as PDF' in the printer list. You get the worksheet and the answer key as a single PDF, on Letter or A4 depending on your printer settings.
Keep the finished 4th grade math word problems worksheets in date order — the drop in time across ten sheets is the clearest progress report you will get.
