If you have ever stared at a blank document thinking, “I just need a simple idea that still scores well,” you are not alone. The truth is most high scoring IB Math IAs are not built on rare, genius level topics. They are built on ordinary situations, a clear question, and math that is explained carefully. If you want the simplest path to success, choose an IB Math IA topic that is easy to control, easy to get data for, and easy to reflect on.

What “simple” means in an IB Math IA
A simple IB Math IA topic is not “too easy.” It is stable. You can collect or find reliable data, apply syllabus level techniques, and evaluate limits without guessing.
Use this quick checklist before you commit:
-
You can explain the context in 3-4 sentences
-
You can do the math with methods you can practice in the IB Math syllabus
-
You can show at least one improvement, limitation, or comparison
-
You can finish a full draft without needing new advanced theory

Simplest IB Math IA topics (that still feel impressive)
Statistics and probability topics (usually the easiest)
These are “simple” because the workflow is predictable: collect data, clean it, model it, interpret.
-
Sports trend analysis: compare player performance to a variable (minutes played, shots, training days). Use correlation, regression, residuals, and comment on reliability.
-
Survey analysis: design a short survey (sleep vs study time, music vs focus). Use measures of central tendency, spread, and a model.

Geometry and trigonometry topics (visual and friendly)
Geometry topics feel manageable because you can show diagrams, define assumptions, and explain each step.
-
Geometry of famous buildings: pick one feature (arches, triangles, domes). Use similarity, trigonometry, or coordinate geometry.
-
Ferris wheel modelling: build a sinusoidal model for height over time, then interpret amplitude, period, phase shift.
If you need a refresher while writing, Geometry and Trigonometry Notes can keep your IB Math language precise.
Calculus topics (simple if you keep the model small)
Calculus becomes “simple” when you avoid messy parameters and keep your assumptions honest.
-
Growth in biology: compare exponential vs logistic models with real data, then evaluate fit.
-
Optimizing packaging: minimize surface area for a fixed volume (or cost). Show derivative steps and interpret constraints.
If you are building calculus confidence alongside the IA, practice with Math AA Calculus Questionbank or Math AI Calculus Questionbank.
Discrete math topics (short, clean, and explainable)
Discrete investigations are often the simplest to write because your steps are logical and finite.
-
Game theory: analyze a simple payoff matrix and explore strategy changes.
-
Cryptography basics: Caesar or Vigenere style encryption, frequency analysis, and limitations.
