Rounding Worksheets

Free printable rounding worksheets. Round four-digit numbers to the nearest ten, hundred and thousand, with an answer key.

Twelve rounding questions a sheet, one per line: round 4,382 to the nearest hundred, and write 4,400 on the rule beneath. The place changes from question to question - ten, hundred, thousand - so the sheet tests choosing the right column to look at, not just the mechanic of rounding once you know it.

The number is never rounded to a place bigger than itself. "Round 47 to the nearest thousand" has the answer zero, reads as a trick, and is not here. Every question can be answered without the number disappearing.

Frequently asked questions

How do you round a number?

Look at the digit one place to the right of the place you are rounding to. If it is 5 or more, round up; if it is 4 or less, round down. Everything to the right of the rounding place becomes zero.

What happens when the deciding digit is exactly 5?

Round up. 4,350 to the nearest hundred is 4,400. This is the "round half up" rule every elementary textbook uses - a share of nearly every sheet lands on it deliberately, because it is the case most often got wrong.

Can I pick which place to round to?

Yes. There are ready-made pages for rounding to the nearest 10 and the nearest 100, or change the Rounding place setting for anything from tens to thousands.

Why do we round numbers?

To estimate. Rounded numbers are easier to add and compare in your head, so rounding is how you check that an exact answer is reasonable. 4,382 + 2,916 should be close to 4,400 + 2,900, which is 7,300.
