About These Worksheets
Grade 4 students round tenths and hundredths while developing a stronger sense of decimal place value.
Rounding decimals worksheets give students focused practice deciding which digit controls the rounding decision and which place value the final answer should end in. This matters because decimal rounding is used constantly in money, measurement, science, and estimation, but students can easily round to the wrong place if they treat every decimal digit the same.
The worksheets practise rounding to the nearest tenth, hundredth, and whole number, with number-line thinking encouraged before shortcut rules. Students learn to identify the target digit, inspect the digit to its right, and keep all digits to the left unchanged. They also see why rounding 4.96 to the nearest tenth becomes 5.0, not 4.10, a common error when students do not understand carrying across the decimal boundary. Decimal rounding strengthens number sense and helps students judge whether answers from calculators or long computations are reasonable.
Skills Practised
- Identifying the target place value before rounding
- Rounding decimals to the nearest whole number
- Rounding to tenths and hundredths
- Using number lines to understand decimal benchmarks
- Checking whether rounded answers are reasonable
Parent Tip: Have your child underline the place they are rounding to before they do anything else. Most decimal rounding errors start because the target place was never identified.
