How we explain it

Children can open this short lesson before they practice.

  1. To round, look at the digit just to the right of your place.
  2. If it is 5 or more, round up. If it is 4 or less, stay.
  3. Change every digit after your place to 0.

Example: Round 4,763 to the nearest hundred. The hundreds digit is 7. Look at the tens digit: 6. 6 is 5 or more, so round up to 8 hundreds. 4,800. Answer: 4,800
