Rounding to 10, 100, 1000
Round any number to the nearest 10, 100, or 1000
Lesson
Set out your lesson
Round positive whole numbers to tens, hundreds and thousands and use rounded values to estimate.
Before teaching
Use this short check, then start teaching.
Learner readiness not observed. Ask for the thousands and hundreds in 4,367. Revisit four-digit place value if either is unclear.
Check learner readiness separately; the existence of a prerequisite lesson is not evidence of attainment.

Rounding to the Nearest Ten and Hundred
Before you open · source notes
Numbers are rounded to the nearest ten and hundred with place-value reasoning. This is rounding practice, not every estimation story.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-11 returned HTTP 200 with no login or payment prompt. Where a teacher solution is present, it is on the same page as the student task; this check did not find a separate locked student view. An adult can use the student view section and should not read a solution aloud. Advertising was not observed in the fetched HTML text; that is not a browser, device, or ad-free guarantee. This is a paper or discussion task, not an automatically marked interactive game. Opening the link does not save practice or assess mastery. Diagrams on the page use missing or filename-only alt text, so they are not an accessible image equivalent. Accessibility still depends on an adult describing the picture.

Check understanding
- Round 4,367 to the nearest 10 (4,370), 100 (4,400), and 1000 (4,000)
- Explain the rounding rule using a number line (which multiple is closer)
- Apply rounding to estimate calculations
“Can your child round a number like 4,738 to the nearest 10 (4,740), 100 (4,700), or 1,000 (5,000) — and explain which digit they look at to decide?”
