Starting your IB Math IA can feel intimidating — especially when you’re staring at a blank page wondering how to begin. Your introduction is more than just an opening paragraph; it’s your chance to hook the reader, show personal engagement, and clearly explain your mathematical goal.
Below, we’ll look at a strong Math IA introduction example, explain why it works, and give you a simple structure to help you write your own.

What Makes a Strong Math IA Introduction?
A great introduction reads like a story — not a science report. It should smoothly connect your curiosity, context, and math focus in a way that feels natural and personal. According to IB’s marking criteria, your introduction should:
Demonstrate personal engagement (Criterion C) by connecting to something that genuinely interests you.
Clearly state your aim — the mathematical question or objective you’ll explore.
Provide enough background to set up your reasoning.
Flow logically and naturally, without abrupt section breaks or unnecessary jargon.
In short, your reader should know:
Why this topic matters to you.
What you’re investigating.
How mathematics will help you answer it.

Math IA Introduction Example: “The Coffee Cooling Curve”
“I’ve always been curious about the little details in everyday routines. Every morning, I make a cup of coffee and notice that it cools down much faster on some days than others. I began to wonder how factors such as room temperature and cup material affect this process. Using Newton’s Law of Cooling, I aim to model how a cup of coffee’s temperature changes over time and determine which conditions keep it warm the longest.”
Why this works?
✅ Personal Connection: The topic comes from a genuine daily observation.
✅ Clear Aim: “To model how a cup of coffee’s temperature changes over time.”
✅ Math Focus: Newton’s Law of Cooling gives the IA clear analytical depth.
✅ Natural Curiosity: The question feels authentic — not chosen just to “tick a box.”
This example works because it’s relatable, mathematically sound, and written like a story that leads to a purpose.
How to Write Your Own Math IA Introduction
Here’s a reliable structure you can use for any topic:
Hook: Begin with a personal story, question, or observation.
Background: Give context and explain what inspired the question.
Math Connection: Introduce the concept or formula you plan to explore.
Aim: State your mathematical objective clearly and specifically.
Example template:
“As someone interested in [personal interest], I often wondered [specific question]. I decided to explore this using [math concept] to model [situation]. My aim is to determine [measurable goal].”
Common Mistakes to Avoid
❌ Writing too broadly — “Math is everywhere in life” is not specific enough.
❌ Forgetting your aim — everything in your introduction should support it.
❌ Overusing clichés or generic problems (like the Golden Ratio or Monty Hall).
❌ Writing mechanically — your IA should sound like your exploration, not a textbook summary.
