Counting Within 1,000
Count within 1000, including skip-counting by 5s, 10s, and 100s
Lesson
Set out your lesson
Count across place-value boundaries without changing the step.
Before teaching
Use this short check, then start teaching.
Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.

Start/stop counting practice supports counting within 1,000. Not every place-value regrouping lesson.
Free, no sign-in. A teacher solution is on the same page, so use the student view with your child.
Before you openAsk the learner to count on from a start number and stop at an adult-chosen end.

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
- Count forwards and backwards within 1000 from any starting number
- Skip-count by 5s from any multiple of 5 to 1000
- Skip-count by 100s from any number (e.g. 150, 250, 350 …)
“Can your child count confidently up to 1000 — and if you ask them to count by hundreds from 200, or by tens from 650, can they do it without losing their place?”
