Introduction
The IB Math IA (Internal Assessment) is one of the most unique challenges in the IB program. It allows students to explore mathematics through a personal investigation. Whether you’re in Mathematics: Analysis and Approaches (AA) or Applications and Interpretation (AI), choosing the right IA topic is crucial.
Strong IB Math IA ideas showcase creativity, personal interest, and mathematical depth. But students often struggle with where to begin.
Quick Start Checklist
- Pick a topic connected to your personal interests.
- Ensure the math matches the level of your course (AA vs AI).
- Use at least one mathematical process beyond the obvious.
- Check that the IA can be explored fully in 12–20 pages.
- Use RevisionDojo resources to structure your writing.
IB Math IA Ideas for Analysis and Approaches
Math AA IA ideas often involve theoretical, proof-based, or algebra-heavy exploration. Examples include:
- Investigating the mathematics of cryptography.
- Exploring convergence of infinite series.
- Modeling population growth with differential equations.
- Analyzing probability in card games with combinatorics.
These topics highlight algebraic reasoning, calculus, and mathematical rigor.
IB Math IA Ideas for Applications and Interpretation
Math AI IA ideas lean toward real-world applications of statistics, modeling, and technology. Examples include:
- Using regression to predict climate change effects.
- Analyzing patterns in music or sports performance data.
- Exploring the mathematics of social media algorithms.
- Modeling business growth with exponential functions.
AI students score best when their projects demonstrate both creativity and practical relevance.
Tips for a High-Scoring Math IA
- Link to your passion: Teachers and examiners appreciate authentic interest.
- Go beyond the obvious: Avoid generic topics like “the golden ratio” unless you add unique analysis.
- Be mathematically accurate: The rubric heavily penalizes errors.
- Structure clearly: Introduction, methodology, results, and reflection should all be present.
FAQ
1. What makes a good IB Math IA idea?
A good IA is personal, mathematically appropriate, and clearly structured.
2. Can I reuse a topic I found online?
Yes, but you must add originality—your approach and analysis must be unique.
3. Which is easier, AA or AI IA?
Neither is easier, but AI often feels more accessible because of real-world data. AA requires more theoretical work.
Conclusion
Whether you’re in IB Math AA or IB Math AI, your IA is a chance to explore math in a way that connects to your world. Strong ideas and structured writing will lead to high marks.
