Georgia 4.NR.1.4
The Standard
Use place value understanding to round multi-digit whole numbers.
Georgia's K-12 Mathematics Standards · Recognize patterns within the base ten place value system with quantities presented in real-life situations to compare and round multi-digit whole numbers through the hundred-thousands place and compare decimal numbers to the hundredths place.

What This Standard Means
What Students Need to Do
- Students round multi-digit whole numbers to a given place, such as the nearest ten, hundred, or thousand. They use place value to decide whether the number is closer to the lower or higher multiple.
What Mastery Looks Like
- Students round the same multi-digit number to any named place and explain which two multiples it falls between. They use the digit to the right or a number line to justify the nearest value.
Common Misconceptions
- Students may look only at the digit being rounded instead of the digit to its right. They may change digits in other places or forget to replace trailing digits with zeros.
How to Assess It
- Give students 47,386 and ask them to round it to the nearest ten, hundred, and thousand. Have them circle the digit that determined each answer.

Ways to Teach It
Place number cards on a floor number line, then have students stand at the nearest labeled ten, hundred, or thousand.
Ask students to explain why 34,650 rounds differently to the nearest hundred and nearest thousand.
Play Rounding Match with cards showing numbers, rounding places, and rounded values that students must combine into correct sets.
Use store prices or town populations and ask students to round each number for a quick estimate.
