Rounding decimals worksheets

Rounding decimals replaces a number with a nearby value at a chosen level of precision. These worksheets ask students to round tenths to the nearest whole number or hundredths to the nearest tenth. Halfway values follow the familiar classroom rule that a deciding digit of 5 rounds up.

The default page uses two-digit whole-number parts and rounds hundredths to tenths. Change the target to whole numbers for an earlier skill, select a smaller number range or create several reproducible versions. The answer key is generated from integer place-value calculations rather than approximate browser arithmetic.

A consistent rounding process

• Identify and underline the digit in the place being rounded.
• Look only at the digit immediately to its right.
• Keep the target digit when the deciding digit is 0 through 4.
• Increase the target digit by one when the deciding digit is 5 through 9.
• Remove digits to the right and check the result against the two nearest benchmark values.

Use benchmarks to explain the answer

For 6.47 rounded to tenths, compare the number with 6.4 and 6.5. It lies beyond the midpoint 6.45, so 6.5 is closer. This distance-based explanation helps students understand the rule and prepares them to estimate decimal calculations rather than memorizing a direction for moving digits.
