Internal Assessment (IA) is a crucial component of your IB Maths journey. As exciting as an independent investigation may be, many struggle from the very beginning: finding the perfect topic is harder than it seems. If you’re one of these students, we’re happy to offer a few fresh IA Maths ideas you can try.

From algebra and geometry to calculus and statistics, these ideas should spark your inspiration and help you approach your IA research project with confidence.

Why it is important to choose unique IA Maths Topics Ideas

Below, you will find 50 diverse IA Maths topics to spark your creativity for the Internal Assessment. Remember, these are just starting points, not blueprints. Copying a title and question directly is not the best approach.

Firstly, thousands of IB students worldwide submit IAs, and your teacher has likely seen similar ideas before. You need to make sure your topic and research question is unique to you to demonstrate independent thinking and effort. What’s even worse, direct copying violates academic integrity. In fact the IB view this as plagiarism.

Nevertheless, these 50+ IA Maths ideas can serve you well as examples to help you come up with your own ideas. You just need to incorporate specific details (location, time frame, or additional factors) to personalise the topic. For example, instead of simply “Modelling the spread of infectious diseases,” you could explore:

  • Modelling the spread of influenza in London during winter 2024-2025.
  • Prediction of the spread of COVID-19 in densely populated areas compared to rural areas during future outbreaks.
  • Analysing the effectiveness of different social distancing measures in controlling the spread of a disease in a specific country.

However, if you’re not inspired by any of the topics or want to figure out how to choose a topic on your own, use our guide – How to choose your Maths IA topic.
