Grade 3 Rounding Worksheets — Nearest Ten and Hundred
Third grade is where rounding first becomes a named skill. Students stop reading a number as a string of digits and start asking which ten or which hundred it sits closest to — the mental habit behind every estimate they will make later. Five sub-skills are offered at this grade and the page opens on Round to the Nearest Ten, where the difficulty control steps from Two-digit numbers, to Three-digit numbers, to Smallest and largest. Round to the Nearest Hundred, Choose the Right Place, Estimate a Sum and Estimate a Difference are separate sheets with three levels of their own — Choose the Right Place is the one that mixes targets so the child has to decide which place is being asked for before rounding.
Every question names its target in words, so there is never any guesswork: "Round 472 to the nearest ten." Choose the level, set how many questions you want, and tick the answer key box to print the answers on their own page. The link in your address bar rebuilds the same sheet exactly, so you can reprint it for a second child or use it again next week.

Grade 3 · 3 pages · A4More Grade 3 rounding skills
Each one generates a different kind of question, with its own three levels and answer key.
- Round to the Nearest TenRound a whole number to the closest ten, using the ones digit to decide.
- Round to the Nearest HundredRound a whole number to the closest hundred, deciding with the tens digit.
- Choose the Right PlaceThe place changes from question to question, so the target has to be read first.
- Estimate a SumRound the numbers first, then add — the quick check before the real answer.
- Estimate a DifferenceRound the numbers first, then take one away — including in word problems.

What rounding looks like in Grade 3
Grade 3 rounding rests on one idea: a number lives between two multiples of ten (or of a hundred), and rounding means choosing the closer one. Before any rule is introduced, it helps to draw a short number line — for 47, mark 40 and 50, put 47 near the right-hand end, and the answer becomes obvious rather than procedural.
Once that picture is secure, the digit rule is a shortcut, not a replacement: look only at the digit to the right of the place you are rounding to. Four or less and the place value stays; five or more and it goes up one. These sheets use the standard round-halves-up convention, and the instruction line on every printout says so, so a child who meets 45 or 250 knows exactly what is expected.
Working through the sub-skills
Start on Round to the Nearest Ten for a week or so — its Two-digit numbers level keeps the values small enough that a child can check the answer by counting on, and Three-digit numbers extends the same decision. Move to Round to the Nearest Hundred once the tens are automatic; the hundreds place is where most children first hit the "look only at the next digit" trap and try to round 349 up because of the 9.
Choose the Right Place is the sheet worth repeating. It shuffles nearest-ten and nearest-hundred questions together on the same page, so the child must read the target before working. That single change turns a mechanical exercise into real thinking, and it is the best predictor of whether the skill will survive into estimation work. Estimate a Sum and Estimate a Difference are where that payoff arrives — rounding first, then adding or subtracting the rounded values. Ten to fifteen questions is plenty for one sitting.
Frequently asked questions
▸How do you teach rounding to the nearest ten in Grade 3?
Start with a number line showing the two tens either side of the number, and ask which one is closer. Once that is intuitive, teach the shortcut: look at the ones digit — 0 to 4 rounds down, 5 to 9 rounds up. Round to the Nearest Ten drills exactly that, starting with Two-digit numbers.
▸What numbers do these Grade 3 rounding worksheets use?
Round to the Nearest Ten runs from Two-digit numbers to Three-digit numbers. Round to the Nearest Hundred works in hundreds. Choose the Right Place mixes both targets on one page, so the child has to read each question rather than repeat the last answer's shape.
▸Does 45 round up or down?
These worksheets use the round-halves-up convention, so 45 rounds to 50 and 250 rounds to 300. The instruction line printed at the top of every sheet states the rule, so a child marking their own work is never left guessing.
▸How many rounding questions should a Grade 3 sheet have?
Ten to fifteen is a good session at this age — long enough to build a habit, short enough to stay accurate. Use the count stepper to size the sheet, and press Shuffle for a completely fresh set at the same sub-skill and level tomorrow.
▸Is the worksheet free, and does it come with answers?
Yes, it is free with no sign-up and no watermark. Tick the answer key box and the answers print on their own page, so you can hand out the questions and keep the key.
