Introduction
The introduction to your IB Math Internal Assessment (IA) is more than a formality—it frames how examiners interpret everything that follows. A strong introduction clarifies your mathematical purpose, signals personal engagement, and prepares the reader for the direction of your exploration. When done well, it supports success in both Criterion B (Mathematical Communication) and Criterion C (Personal Engagement). This guide explains what makes an effective Math IA introduction and how to structure it for maximum impact.
Why the Math IA Introduction Matters
A well-written introduction:
- Demonstrates personal engagement, directly supporting Criterion C
- Provides clear context so your investigation is easy to follow
- Establishes a focused, manageable research question
- Helps examiners understand your intent and mathematical direction from the outset
First impressions matter—examiners often form expectations about clarity and originality within the opening section.
Five Essential Elements of a High-Scoring Math IA Introduction
1. Begin with an Engaging Hook
Start with a compelling question, observation, or real-world connection related to your topic. This shows that your exploration is motivated by curiosity, not just syllabus coverage.
Example:
Why do certain combinations of musical notes sound harmonious while others feel dissonant? The answer lies in mathematical frequency ratios.
2. Explain Your Personal Motivation
Briefly explain why you chose this topic. Examiners are looking for ownership and genuine interest—not a long story, but a clear connection.
Tip:Link your investigation to a hobby, real-life experience, or curiosity that naturally led you to the mathematics.
