IB Mathematics · Example work

Analyse example work—do not reproduce it.

Curated PDF and HTML documents help students compare structure, mathematical communication, reasoning and reflection.

Curated library

Source, curriculum version and learning value must be visible.

Example work can show how a research question is focused, how mathematics is explained and how results are evaluated critically. It is not a template to be repeated with different numbers or a new context.

Initial collection: official legacy IB examplesThe Mathematics EE examples below come from the official IB Publishing collection and include examiner commentary. They belong to a legacy EE curriculum and should therefore be read as historical learning examples.

How the library will grow

Every item receives verifiable metadata.

The future collection will distinguish clearly between official work, school-published work and material shared with author permission.

Source & rights

Record the original source, publication status and any usage restrictions.

Document data

Capture format, language, page count, assessment type, mathematical area and curriculum version.

Editorial guidance

Explain strengths, visible limitations and specific learning points in original wording.

Academic integrity

Ask five questions while reading.

  • How focused is the research question?
  • How is the mathematics explained?
  • Which decisions are genuinely independent?
  • How are results checked and reflected upon?
  • Which weaknesses are stated or visible?

Examples show possibilities—the student's own question gives the paper direction.

Use the topic collection to develop an independent starting point.
