How to Choose the Perfect IB Math IA Topic

Example:

“After analyzing my own running data over a month, I modeled how weekly mileage influenced my average pace using linear regression.”

RevisionDojo’s IA Personalization Prompts guide you through turning general ideas into authentic personal investigations.

Step 3: Ensure It’s Mathematically Rich

Your topic must involve substantial mathematics — not just descriptive statistics or simple algebra.

Ask:

• Which mathematical tools will I use?
• Does it involve problem-solving, modeling, or reasoning?
• Can I connect it to at least two syllabus areas?

RevisionDojo’s Math Depth Checker flags topics that might be too simple and suggests ways to deepen them.

Step 4: Narrow the Focus

Many students start with topics that are far too broad.
Instead of “modeling population growth,” try “modeling the population growth of honeybees using a logistic model.”

Specificity makes your IA manageable and meaningful.
RevisionDojo’s Topic Refiner Tool helps condense broad concepts into focused, research-ready questions.

Step 5: Avoid Overused or Risky Topics

Some topics are too common or mathematically limited.
Avoid things like:

• “Golden ratio in art”
• “Fibonacci in nature”
• “Math behind music scales”

They sound appealing but rarely allow deep analysis.

RevisionDojo’s IA Topic Vault highlights overused ideas — and shows creative alternatives that still connect to your interests.

Step 6: Test for Mathematical Feasibility

Ask yourself:

• Can I collect or access the data I need?
• Can I perform the necessary calculations?
• Does the math fit within IB’s syllabus scope?

RevisionDojo’s Feasibility Filter evaluates topics for data availability, technical difficulty, and time requirements — before you commit.

Step 7: Choose Between Primary and Secondary Data

If your topic involves data, decide whether you’ll collect it yourself or source it externally.

• Primary data: Adds personal engagement and originality.
• Secondary data: Easier to manage but must be clearly cited.

RevisionDojo’s Data Source Guide provides examples and best practices for both methods.

Step 8: Draft a Clear Aim or Research Question

Every topic needs a strong mathematical aim — this is your IA’s compass.

Example format:

“This investigation aims to model how [variable A] affects [variable B] using [mathematical method].”

RevisionDojo’s Aim Builder helps you phrase your research question precisely and mathematically.

Step 9: Check Against the IB Rubric

Your topic should allow you to demonstrate:

• Personal Engagement – Your genuine interest and originality.
• Mathematical Communication – Clear presentation of reasoning.
• Reflection – Discussion of results and limitations.

RevisionDojo’s Rubric Alignment Tool checks if your chosen topic can realistically score well in all criteria.

Step 10: Get Early Feedback

Before finalizing, share your topic idea with a teacher or peer.
Ask:

• Is this mathematically deep enough?
• Is it too complex for the IA length?
• Does it sound genuinely interesting?

RevisionDojo’s IA Draft Review Tool helps you gather feedback and refine your idea before writing begins.

Frequently Asked Questions

1. What’s the best type of IA topic?
One that’s personal, feasible, and mathematically rich — ideally something you can model or analyze quantitatively.

2. Should my topic be related to real data?
Not always, but real-world data often makes your analysis more authentic and engaging.

3. How much originality does IB expect?
You don’t need a brand-new discovery — just a unique approach or personal twist on your topic.
