Rounding Decimals to Whole Numbers and Tenths
Use this worksheet to teach rounding decimals to whole numbers and tenths. Work through one example with your student before assigning independent practice.
Teaching notes for parents and teachers
Use this worksheet to teach rounding decimals to whole numbers and tenths. Work through one example with your student before assigning independent practice.
How to teach it
Place the decimal between the two possible rounded values on a number line. Identify the midpoint, then connect the nearer endpoint to the digit rule. For these positive-number examples, explain that an exact midpoint rounds up.
Examples to explain together
The hundredths digit is 6, so increase the tenths digit from 4 to 5.
The tenths digit is 4, so keep the whole-number part.
If your student needs help
If your student rounds in several stages, return to the original number and the requested place. Rounding an intermediate result can change the final answer.
Check understanding
Have your student name the two neighboring possible answers and explain which is closer to the original number.
Make a practice set
Select the worksheet, answer key, or both. When both are selected, the answer key prints after the questions. Keep it separate if you want your student to work independently.
After your student finishes
Review one problem together. Ask your student to explain the steps, then use the answer key to check the result. Revisit a difficult step before assigning another set.
About Rounding Decimals to Whole Numbers and Tenths
Practice rounding decimals to whole numbers and tenths. Focus on accuracy before speed. Use the space provided to record the steps you need.
How to practice
Identify the requested place first. Look one place to its right: a digit from zero to four keeps the target digit, while five to nine increases it by one. Remove the digits beyond the requested place after completing any carry. A whole-number answer and an answer to the nearest tenth use different target places.
Examples to explain together
The hundredths digit is 6, so increase the tenths digit from 4 to 5.
The tenths digit is 4, so keep the whole-number part.
If your student needs help
Do not round an intermediate digit first. Read the requested place in each question rather than applying the same place to the whole sheet.
Check understanding
Locate the two neighboring whole numbers or tenths. The rounded value should be the nearer neighbor; an exact midpoint rounds upward for these positive-number examples.
Before independent practice
Work through one example together. Ask the student to explain one step, then try a few questions independently. Review the cause of an error before repeating the calculation. Compare the student’s written steps with the answer key where worked steps are provided; a correct answer alone does not show which strategy was used.
