Introduction
The IB Extended Essay in Mathematics (IB Math EE) is one of the most challenging and rewarding parts of the IB Diploma Programme. Unlike typical coursework, the Math EE requires you to independently investigate a mathematical question, idea, or application in depth. For many IB students, it’s their first taste of real mathematical research.
But with that challenge comes uncertainty: how do you choose a topic? What level of math is appropriate? And how do you structure the essay to meet IB standards? This guide provides everything you need to confidently tackle your IB Math EE and maximize your potential.
Quick Start Checklist
Before diving into writing, here’s a rapid checklist for your Math Extended Essay:
- Select a topic you genuinely find interesting (sports, finance, coding, physics, etc.).
- Ensure the math goes beyond your HL or SL syllabus.
- Review past Math EE exemplars to understand depth and scope.
- Create a clear research question that can be answered mathematically.
- Use RevisionDojo resources for essay structure and exam-ready strategies.
Choosing a Math EE Topic
The most important step in writing a Math EE is the topic selection. A strong Math EE topic is:
- Mathematically rich: It should explore concepts deeper than classroom exercises.
- Personalized: Link it to your interests—this keeps you motivated.
- Researchable: Ensure you can find enough sources and data to work with.
Examples of excellent Math EE topics:
- Game theory applications in economics or strategy.
- Fractals and chaos theory in modeling natural systems.
- The mathematics of cryptography and coding systems.
- Modeling population growth with differential equations.
- Probability in sports performance analysis.
Avoid overly simple or generic topics (like just “the Fibonacci sequence”) unless you can add a fresh, analytical angle.
Structuring the IB Math EE
A successful Math EE follows a clear structure:
- Introduction – Present the research question and context.
- Background Theory – Explain necessary math concepts.
- Methodology – Show how you approach the problem.
- Exploration & Analysis – Carry out calculations, proofs, or models.
- Discussion – Reflect on the significance of results.
- Conclusion – Summarize findings and address limitations.
- References & Appendices – Cite all sources, include graphs or calculations.
Examiners reward clarity and logical flow. Even if your math is complex, make sure your explanations are accessible.
Common Pitfalls to Avoid
- Lack of depth: Using only SL-level math without extension.
- Overly broad topics: A vague question makes the essay unfocused.
- Weak structure: Jumping between ideas without logical order.
- Poor reflection: The EE requires personal engagement and evaluation.
Remember: examiners want to see both mathematical skill and critical thinking.
How the Math EE is Graded
The Math EE is assessed using the standard EE rubric, with emphasis on:
- Focus and method (topic choice, research question).
- Knowledge and understanding (mathematical depth).
- Critical thinking (analysis and evaluation).
- Presentation (organization, visuals, notation).
- Engagement (student’s personal voice and reflection).
A well-written Math EE can contribute significantly to your diploma points, especially combined with TOK for the bonus marks.
Tips for Success
- Start early: Research takes longer than you think.
- Write clearly: Use diagrams, graphs, and step-by-step proofs.
- Check IB criteria: Always align your essay with the official rubric.
- Seek feedback: Use your supervisor for guidance.
- Practice reflection: Show how the EE developed your thinking.
Frequently Asked Questions (FAQs)
1. Can I write a Math EE if I’m not in Math HL?
Yes, but it’s recommended for HL students because the EE demands mathematics beyond the SL syllabus. If you’re SL, choose a topic carefully to ensure enough depth.
2. How long should my Math EE be?
The EE has a maximum of 4,000 words. For Math, quality matters more than hitting the word count. Many strong essays are around 3,500–3,800 words with graphs and equations.
3. What makes a Math EE score highly?
A focused research question, mathematical depth beyond the syllabus, clear structure, and strong reflection. Originality—such as applying math to your passion—can also impress examiners.
4. Can I use technology in my Math EE?
Absolutely. Graphing software, coding tools, or spreadsheets can help model data and illustrate points. Just ensure you explain the math behind the technology.
5. Should I prioritize theory or applications?
Both can work. A theoretical essay (like on number theory) or an applied essay (like modeling business growth) can score well—what matters is depth, clarity, and engagement.
Conclusion
The IB Math Extended Essay is a rare opportunity to explore mathematics in a way that goes beyond exams. By choosing a meaningful topic, applying advanced math, and structuring your essay carefully, you can not only impress examiners but also enjoy the process of mathematical discovery.
