“1000 More or Less 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
- Counters or paper models for the idea
- Pencil for recording
Extra for the adult
Worked example. Adult shows one clear example for 1000 More or Less, then the child tries a matching example with a reason.

What to notice. Keep one parent note: examples tried; results; support used. This session samples 1000 More or Less, not mastery.

1000 More or Less means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.

Done: three correct examples with a spoken reason each. Stop after the fresh check; keep optional challenge for another day.

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
- Given 4,562, state that 1000 more is 5,562 and 1000 less is 3,562
- Explain using place value that only the thousands digit changes
- Apply this skill to numbers beyond 10,000
“Can your child quickly work out '1,000 more than 3,456' or '1,000 less than 7,200' in their head — knowing only the thousands digit changes?”
