How to Choose the Perfect IB Math IA Examples/Topics: A Step-by-Step Guide for N24 and M25

Author: Emily Carson, IB Examiner, and Math Expert

Emily Carson has been working with IB students for over 10 years as an IB examiner and teacher. She is the perfect person who can share IB Math IA examples. She’s seen hundreds of students make the same mistakes when choosing their Math IA topic. So, today she’s here to share her best tips for picking the perfect IB Math IA examples/topics that will not only interest you but also help you score top marks in your N24 or M25 session.

Why Choosing the Right IB Math IA Topic Matters

Your Math IA isn’t just another school project; it’s a huge part of your final IB grade. Picking the right topic can be the difference between scoring a 7 or struggling with a 4. If you choose a topic that excites you and allows you to dive into the math you love, you'll enjoy the process more—and the examiners will see that in your final work.

But how do you choose the perfect topic? Let’s break it down step by step.

Step 1: Start with What You Love

Choosing a topic that interests you is key. Think about the areas of mathematics that you genuinely enjoy. Are you fascinated by statistics, calculus, or geometry?

For example:

• If you enjoy statistics, you could explore topics like “Analyzing the Probability of Winning in Sports Tournaments” or “Predicting Election Outcomes with Statistical Models.”
• If geometry is your thing, you might be interested in something like “The Mathematics Behind Famous Architectural Designs” or “Exploring Tessellations in Islamic Art.”

Not only will these ideas keep you motivated, but they will also allow you to create something unique, showing off your personal strengths in math.

Pro Tip: Search for IB Math IA examples online to see what topics have been successful for other students. This will help spark your creativity while giving you a sense of what works.

Step 2: Find Real-World Applications

The IB loves to see real-world connections in your IA. Your topic should apply mathematics to a real-world problem or scenario. This makes your IA more engaging and demonstrates that you understand how math impacts everyday life.

Examples of real-world applications include:

• Using game theory to analyze strategies in poker.
• Modeling traffic flow with calculus.
• Exploring math in nature, like the Fibonacci sequence in flowers or shells.

For example, you could dive into “How Calculus Helps Optimize Traffic Flow in Urban Areas” or “The Use of Probability in Predicting Election Outcomes.”

Why This Works: IB examiners are looking for how well you can apply math to real situations, and using practical examples will show you’ve thought deeply about the implications of your work.

Step 3: Make Sure There's Enough Mathematical Depth

Your IA needs to be challenging but achievable. It’s not enough to pick a topic that you enjoy; it also needs to have enough mathematical complexity to show your skills. Look for a topic that allows you to explore high-level math, whether that’s calculus, statistical analysis, or algebra.

For instance, instead of a simple topic like “The Probability of Rolling a Six on a Dice,” you could go deeper with “The Probability of Winning in Games of Poker Using Conditional Probability.” This allows you to explore statistical models and probability theory in greater detail.

Key Insight: Your topic should be mathematically rich, but don’t overcomplicate it. You want enough depth to impress examiners without biting off more than you can chew.

Step 4: Narrow Down Your Topic

Now that you have a general idea, it’s time to refine it. A broad topic won’t let you go into the necessary depth. Try to focus on a specific question or area of math.

For example, instead of exploring “Math in Architecture,” you could focus on “The Role of the Golden Ratio in Gothic Cathedrals.” This allows you to dig deeper into one area, giving you a better chance of explaining your mathematical reasoning fully.

Pro Tip: Keep your topic focused and realistic. Look at IB Math IA guidelines to ensure your topic fits within the scope of what’s expected.

Step 5: Test the Feasibility

Before you commit to your topic, make sure it’s actually feasible. Ask yourself:

• Do I have access to the data I need?
• Can I complete the calculations within the word count?
• Will this topic allow me to show off my math skills?

For example, a topic like “Predicting Climate Change with Mathematical Models” might be interesting but too broad. Instead, you could explore something more specific, like “Modeling Temperature Changes in a Specific Region Over 50 Years.”

Step 6: Get Feedback Early

Once you’ve got a rough idea for your topic, don’t be afraid to ask for feedback from your teacher, peers, or even an IB examiner. They’ll help you refine your topic and ensure you’re on the right track before you get too far along.

Common Questions About Choosing an IB Math IA Topic

Q: What are some high-scoring IB Math IA topics?

A: Here are a few examples:

• “The Effect of Population Growth on Traffic Congestion: A Mathematical Model”
• “The Use of Game Theory to Analyze Strategic Decisions in Sports”
• “Exploring the Use of the Golden Ratio in Architecture”

Q: Can I change my Math IA topic halfway through?

A: Yes, you can, but it’s not recommended unless absolutely necessary. Changing topics late in the process could make it difficult to complete your IA on time.

Q: How do I know if my topic has enough mathematical depth?

A: Your topic should involve advanced math concepts like calculus, algebra, or statistics. If your topic allows you to demonstrate these skills, it likely has enough depth.

Final Thoughts

Choosing the right IB Math IA topic for N24 or M25 can make all the difference in your final score. By starting with your interests, applying math to real-world scenarios, and ensuring there’s enough depth to your topic, you’ll be well on your way to writing an IA that not only scores highly but also keeps you engaged from start to finish.

Remember, this is your opportunity to showcase your unique strengths in mathematics, so choose a topic that excites you, and get ready to impress the examiners!
