What This Standard Means
What Students Need to Do
- Students find the requested decimal place and examine the digit immediately to its right. They decide whether the target digit stays the same or increases by one.
What Mastery Looks Like
- Students locate the requested place, check the digit directly to its right, and adjust correctly. They write a rounded value with no extra digits after the target place.
Common Misconceptions
- Students may change only the target digit and leave later digits in the answer. They may round based on the target digit instead of checking the digit immediately to its right.
How to Assess It
- Exit ticket: Round 6.487 to the nearest whole number, tenth, and hundredth. Circle the digit used to make each decision.

Play Rounding Match with cards showing decimals and possible rounded values, asking students to pair each number with the correct result.
Use grocery prices to round costs to the nearest dollar or tenth, then compare the estimate with the exact total.
