Rounding whole numbers and decimals

Round decimals to any place using place-value understanding; round any whole number to a required degree of accuracy

Lesson

Set out your lesson

Round positive decimals and whole numbers to a stated place. Use rounding to estimate a product.

Before teaching

Use this short check, then start teaching.

Activity

Ask the learner to name tenths, hundredths and thousandths in 4.582. Expect 5 tenths, 8 hundredths, 2 thousandths. Ask for 63 rounded to the nearest ten: 60. If unclear, revisit the named reading and rounding prerequisites. Explain that a fourth decimal digit names ten-thousandths.

Policy

Check readiness directly. Prerequisite availability is not attainment.

Printer, credit, and teaching notes

Check readiness directly. Prerequisite availability is not attainment.

Use these linked lessons over several short sessions. Start with the readiness check; if it is not secure, revisit the named prerequisites rather than treating source availability as learner readiness. Use Show, Guided, then Try. Read the active sheet on screen and answer on plain paper or by typing. No printer, cutting, purchase or internet is needed. The adult may read the exact prompt. Record any hints, scribing or calculation help. Oral explanations do not show independent reading or handwriting. Use extra space and time as needed; pause or split the lesson. Keep this adult guide and all keys private. Share only the active learner sheet. Before Try, put Show, Guided work and notes aside. Keep the Try givens available, including a unit table if supplied. Give no answer or target step during the first attempt. If help is needed, give it and mark the attempt supported. Review keys after the attempt. Record the actual response and help; do not invent success or infer mastery from one attempt. These are fictional paper or oral mathematics tasks. No personal information, public sharing, purchase, real transaction, physical experiment or real measurement is required.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Check understanding

  • Round 3.4567 to 2 decimal places (3.46)
  • Round 7,654,321 to the nearest 100,000 (7,700,000)
  • Use rounding to estimate 4.83 × 2.17 ≈ 5 × 2 = 10
“Can your child round a decimal like 3.748 to one decimal place (3.7) or two decimal places (3.75) — and explain which digit they look at to decide?”
