About Rounding

What this skill is

Rounding is replacing a number with an approximate value that is simpler to calculate with, based on which benchmark ten, hundred, or thousand the number is closer to on a number line.

When children learn it

Rounding two-digit and three-digit numbers to the nearest 10 and 100 begins in 3rd grade (CCSS 3.NBT.A.1) and extends to rounding multi-digit numbers to any place in 4th grade (CCSS 4.NBT.A.3).

Teaching Tips

  • Use the "Roller Coaster Rule": circle the target place, underline the neighbor to the right. If the neighbor is 0-4, the car rolls backward (stays the same); if 5-9, it rolls over the hill (rounds up). All digits behind become zeros.

Common Mistakes

  • Looking at the wrong digit, examining the rounding place itself rather than the neighbor digit to its right.
  • Forgetting to change all digits to the right of the rounding place into zeros after rounding.
  • Struggling with the benchmark midpoint rule (that 5 rounds up to the higher ten).
