About these worksheets
Rounding decimals is the same look-right-and-decide rule children know from whole numbers, applied one column further along: to round to the nearest tenth, the hundredths digit decides. Mixing whole-number and tenth targets on one page forces reading the instruction, not pattern-matching. The persistent error worth watching: 3.97 rounding to 4.0, where the carry ripples across the decimal point.
Grade level: these worksheets are part of our 5th grade math worksheets collection.
Frequently asked questions
How do you round to the nearest tenth?
Look at the hundredths digit: 5 or more rounds the tenths digit up, 4 or less leaves it. 3.47 → 3.5; 3.43 → 3.4.
Why mix rounding targets on one page?
So the child has to read each instruction. Deciding which digit to look at is most of the skill.
Why do some answers end in .0?
Rounding to the nearest tenth keeps the tenths digit, even when it is 0. So 8.02 rounds to 8.0, not 8, and the keys write it that way. Writing 8 would be rounding to the nearest whole number, the other kind of problem on the sheet.
