Rounding to a Given Place Value
Rounding to a Given Place Value is a Grade 5 math skill from Eureka Math that teaches students to round whole numbers and decimals to any specified place. Students identify the digit in the target place and look at the next digit to decide whether to round up or keep the digit. This systematic approach applies uniformly to ones, tens, tenths, hundredths, and beyond.
Key Concepts
To round a number to a specific place value, look at the digit immediately to the right of that place. If the digit is 5 or greater, round up the digit in the target place value. If the digit is less than 5, keep the digit in the target place value the same. All digits to the right of the rounded place value become zero.
Common Questions
How do you round a number to a given place value in Grade 5?
Find the digit in the target place. Look at the digit directly to its right. If it is 5 or more, round up (increase the target digit by 1); if it is less than 5, round down (keep the target digit). Replace all digits to the right with zeros or drop them if decimal.
How do you round 3.467 to the nearest hundredth?
The hundredths digit is 6. The next digit (thousandths) is 7, which is 5 or more, so round up: 3.467 rounds to 3.47.
What place values do Grade 5 students round to?
Grade 5 students round to any whole number place (ones, tens, hundreds, thousands) and any decimal place (tenths, hundredths, thousandths).
What Eureka Math Grade 5 chapter covers rounding to a given place value?
Eureka Math Grade 5 covers rounding to any specified place value in its decimal and number sense chapters, extending rounding skills to include decimal places.
Why is rounding to a specific place important in Grade 5?
Different contexts require different levels of precision. Rounding to the appropriate place ensures answers are both accurate enough for the context and expressed in a clear, usable form.
