1 approach
Carrying out a statistical investigation means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Place-value cards or columns (hundreds/tens/ones); Digit cards 0–9. Adult builds 243 and names hundreds, tens, ones. Child builds three numbers and names each place. Done: three numbers built with correct place names. Stop after the fresh check; keep optional challenge for another day.

Identifying statistical questions supports starting a statistical investigation. Not every mean formula.
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 sort questions into statistical vs not and say why.

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
- Investigate 'Which playground equipment is used most at lunch?' by tallying observations over three days or by collecting survey responses
- Represent the results in a bar graph with a title and labelled axes, by hand or with a digital tool
- Write two sentences answering the investigation question using the data
“If your child's class asks 'Which fruit do we eat most at recess?', can they help collect the data, make a graph, and say what the results show?”
