Representing numbers to 1000
Identify, represent and estimate three-digit numbers using different representations: place a number on a 0–1000 number line marked only in hundreds or unmarked, estimate the value of a marked point, and represent a number with base-ten blocks (hundreds, tens and ones), a place-value chart and a drawing, including numbers with a zero digit and non-standard partitions
Lesson
Set out your lesson
“Representing numbers to 1000 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 cards or columns (hundreds/tens/ones)
- Digit cards 0–9
Extra for the adult
Worked example. In 243, the 2 means 2 hundreds, the 4 means 4 tens, the 3 means 3 ones.
Optional challenge. For Representing numbers to 1000, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Representing numbers to 1000, not mastery.

Counting stamps supports representing numbers toward 1000 with hundreds, tens, and ones. Not every fraction model.

Source, access and review notes
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
- Mark 346 in about the right place on a 0–1000 number line marked in hundreds (between 300 and 400, a little before halfway), and estimate that an unlabelled point three-quarters of the way along is about 750
- Represent 507 with physical or on-screen base-ten blocks and on a place-value chart, showing the empty tens column as 0
- Match a drawing of 3 hundreds, 14 tens and 2 ones to the numeral 442
“If your child sees a number line from 0 to 1000 marked only in hundreds, can they point to roughly where 346 goes — and show 346 another way, such as hundreds, tens and ones blocks or a place-value chart?”
