Rounding tenths to whole numbers
Round decimals with one decimal place to the nearest whole number
Lesson
Set out your lesson
“Rounding tenths to whole numbers means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Place-value grid (ones / tenths)
- Pencil
Extra for the adult
Worked example. Three tenths on the grid is 0.3.
Optional challenge. For Rounding tenths to whole numbers, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Rounding tenths to whole numbers, not mastery.

Public Illustrative Mathematics task page. The .html address responds HTTP 308 to this URL. An anonymous GET of this URL on 2026-11-12 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 3.7 to 4 and 3.2 to 3
- Place 6.5 on a number line between 6 and 7 and decide it rounds to 7
- Round a set of one-decimal-place numbers and explain the rounding rule
“If your child measures something as 3.7 m, can they tell you whether that rounds to 3 m or 4 m — and explain why?”
