A student wants to measure a pencil about 3 cm long to the nearest millimetre. Which tool and unit best match that purpose?
Show worked steps
Answer: A ruler marked in millimetres
- The quantity is a short length.
- Millimetre ruler marks allow finer readings than centimetre-only marks.

These quizzes practise concepts within this topic. Multiple-choice answers alone do not demonstrate drawing, conducting an investigation or using a digital tool.
Activities to practise beyond the quiz
- Supported by the guided activity; selecting an MCQ does not demonstrate this action.
- VC2M5M01-C01Match length, mass or capacity to the tool and unit. Check that the tool’s range can hold the whole measurement and that its graduation spacing resolves the required detail.
- VC2M5M01-C02A measurement such as 2 m 24 cm keeps detail hidden by “about 2 m”. Measuring with finer marks can provide more information. Merely rewriting a rounded value in smaller units or adding zeros does not recover lost detail.
- VC2M5M01-C03Choose a scale suited to the decision. Coarse rounding may hide differences between two jumps or capacities. Displayed decimal places do not by themselves establish the instrument’s accuracy; distinguish measured information from formatting.
- VC2M5M01-C04Choosing and using physical measuring tools; obtaining and comparing real measurements.
