Animal population figures prompt multiplicative comparison language such as times as many. Not every ratio table.
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 write a multiplicative comparison sentence from the population numbers.

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
- Explain that '4 times as many' means multiply by 4
- Write an equation for: Sarah has 3 times as many stickers as Tom, who has 8 stickers
- Distinguish multiplicative comparison from additive comparison in word problems
“Can your child look at '35 = 5 × 7' and explain it as '35 is five times as many as 7' — understanding it as a comparison, not just a multiplication fact?”
