MODEL paper flag starts at 4 cm and ends at 17 cm on a labelled ruler. Strip A is 11 cm; strip B is 16 cm. A job needs at least 15 cm. These are supplied readings, not measured classroom objects.
Usual communication, exact scribing, private/untimed response, rest or pause are welcome. An adult may read/describe all source facts neutrally, without choosing your maths or giving answers. These supplied models do not establish real measuring.
1. Choose a useful unit and tool for the length of a small paper flag. Explain why.

3. Which strip meets the job, and how much spare length does it give?
Own response: [empty before your attempt]
4. Explain one way to check the flag reading on a real safe ruler if an adult approves. What cannot the paper answer show?
