What This Standard Means
What Students Need to Do
- Students locate the hundredths and thousandths digits in a decimal. They use the thousandths digit to decide whether the hundredths digit stays the same or increases by one.
What Mastery Looks Like
- Students correctly round decimals such as 2.473 to 2.47 and 6.998 to 7.00. They can name the deciding digit and explain why the hundredths digit changes or stays.
Common Misconceptions
- Students may look at the hundredths digit instead of the thousandths digit when deciding whether to round up. They may simply drop extra digits, forget to carry, or write 6.5 instead of 6.50.
How to Assess It
- Exit ticket: Round 3.746 and 8.995 to the nearest hundredth. Explain which digit determined each answer.

Ways to Teach It
Build decimals with digit cards on a place value chart, then move each number to its nearest hundredth.
Ask, “Is 4.376 closer to 4.37 or 4.38?” Students write a claim using distance to support it.
Play Round and Cover: students draw decimal cards, round to hundredths, and cover matching answers on a game board.
Give prices with three decimal places, such as $2.786, and have students round each price to the nearest cent.
