Measurement questions with worked solutions

Each question is generated from an existing curriq QDSL archetype at a fixed seed. Marks and catalog content mappings travel with the generated question.

Worked example 1

Content mapping and common errors

Measurement content identifiers

MS-M1

Applications of Measurement

Solve measurement problems involving perimeter, area, surface area and volume of standard and composite shapes and solids.

Common student mistakes
  • ·Using diameter instead of radius in circle formulas
  • ·Forgetting to add all faces when computing surface area of composite solids
  • ·Misidentifying the correct formula (e.g., using area instead of volume)
MS-M2

Working with Time

Perform calculations involving time and duration, time zones, and scheduling in practical contexts.

Common student mistakes
  • ·Converting minutes to hours as a decimal incorrectly (e.g., treating 30 min as 0.30 h not 0.5 h)
  • ·Errors with AM/PM conversion when calculating duration across midnight
MS-M6

Non-right-angled Trigonometry

Apply the sine rule, cosine rule, and area formula to solve problems with non-right-angled triangles.

Common student mistakes
  • ·Using sine rule when cosine rule is required (ambiguous case misidentification)
  • ·Errors in bearing problems — confusing true bearing and compass bearing
  • ·Forgetting the ambiguous case of the sine rule
MS-M7

Rates and Ratios

Solve problems involving rates and ratios in practical contexts, including unit conversions and scale factors.

Common student mistakes
  • ·Incorrect unit conversion (e.g., km/h to m/s)
  • ·Simplifying ratios without expressing in lowest terms

Source and methodology

Examples are deterministic curriq catalog generations from existing QDSL archetypes at the published fixed seed. The generator copies only student-facing prompts, mark allocations, topic mappings, display tables or options, checked answers and marking-path results into this resource.
