Choosing the right IB Maths IA topics for Hong Kong is often harder than writing the IA itself. Many Hong Kong students either pick topics that are far too complex or struggle to find ideas that feel “good enough.”
At Mathzem, we help students select IA topics that are realistic, syllabus-aligned, and score well under IB marking criteria. This guide shares some of the best IB Maths IA topic ideas for Hong Kong students for both AA and AI, at SL and HL.

What Makes a Strong IB Maths IA Topic?
Before looking at examples, it’s important to understand what IB examiners value.
A strong IA topic is:
- Clearly mathematical
- Closely linked to the syllabus
- Narrow and focused
- Easy to explain and reflect on
Complexity is less important than clarity and reasoning.
AA IA Topic Ideas (SL & HL)
AA IAs should focus on algebra, functions, or calculus.
1. Optimisation Problems
Examples:
- Minimising material cost for packaging
- Optimising dimensions of a container
These topics:
- Use calculus naturally
- Are easy to explain
- Score well when structured clearly
2. Modelling Motion
Examples:
- Modelling the trajectory of a ball
- Analysing speed vs time using calculus
Strong choice for students comfortable with functions and derivatives.
3. Trigonometric Modelling
Examples:
- Modelling tides or daylight hours
- Sound wave analysis
Clear real-world link with manageable maths.
4. Function Transformations
Examples:
- Investigating transformations in architecture
- Comparing different functional models
Excellent for SL students aiming for clarity.
AI IA Topic Ideas (SL and HL)
AI IAs should focus on statistics, probability, and modelling.
1. Statistical Analysis of Real-World Data
Examples:
- Analysing exam score distributions
- Studying correlations in sports or economics
Very popular but must be focused and well explained.
2. Probability and Risk
Examples:
- Analysing game strategies
- Comparing probabilities in real-life scenarios
Works well when supported by simulations.
3. Regression and Modelling
Examples:
- Predicting trends using regression
- Comparing different models
Strong AI HL topics when interpretation is clear.
4. Data-Driven Social Topics
Examples:
- Public transport efficiency
- Environmental data analysis
Relevant to Hong Kong and easy to justify.
Topics Hong Kong Students Should Avoid
At Mathzem, we strongly discourage:
- University-level maths
- Overly broad investigations
- Topics with unclear maths focus
- IA ideas chosen “just to impress”
These often score lower than simple, well-explained topics.
How to Narrow Your IA Topic Effectively
Once you have an idea:
- Identify the specific maths involved
- Define a clear research question
- Limit scope early
- Ensure alignment with your course
A narrow topic is easier to execute well.
