About Rounding Decimals

What this skill is

Rounding decimals replaces a decimal value with an approximation to a specified place value, based on whether the subsequent digit is 5 or greater (round up) or 4 or less (round down).

When children learn it

Rounding decimals to any place is a core 5th grade standard (CCSS 5.NBT.A.4).

Teaching Tips

  • Circle the place you are rounding to, and underline the digit to its right. If the underlined digit is 5 or more, add 1 to the circled digit and drop all digits after it. Dropping everything after the rounded place prevents trailing zero confusion.

Common Mistakes

  • Leaving trailing zeros after the rounded decimal place when not required, or adding zeros that change the required precision.
  • Looking at the wrong digit when deciding whether to round up or down.
  • Rounding whole numbers when the instructions ask to round to the nearest tenth.
