Choosing IB Math Internal Assessment Topic

Quickest way to narrow a topic for IB Math Internal Assessment

Many students are at a loss when it comes to writing their IB Math Internal Assessment. Previously, I have written guides to the Top 5 mistakes made in IB Math Explorations and 5 tips to acing your IB Math Exploration. I received some requests from students on tips to how to choose a topic for their Math Internal Assessment.

Here are some pointers to help you select the most suitable topic.

  1. Brainstorm on topics you are interested in.

Create a mind map of the topics that interest you. List out areas that you can relate to and are close to your heart. A good way to start is to identify topics that are sparked off by things in your own life.

  1. Research on the topics that you have listed.

Read Math journals on all the topics which you have mapped out. Google Scholar is a great place to search for free journals. Narrow down on the topics which you fully understand.

  1. Check the IB Math guide

Make sure the topic you have chosen makes use of Math that is at least of the same level as found in the IB Math guide. It is perfectly fine to use Math that is beyond your IB syllabus. Do make sure you are able to demonstrate real understanding of the Mathematics used. A common mistake made by students is applying complicated Math without good knowledge of the Math involved.

  1. Avoid Common Topics

According to the IB Math subject guide, common topics such as the Fibonacci sequence, the golden ratio, the Monty Hall problem and the SIR model for epidemics, casino games, cryptography, graphing musical tones, and projectile motion are often chosen for Internal Assessment. These topics are often poorly done and do not score a good grade. Try to avoid these topics.
