How to Approach Problem-Solving Questions in IB Math SL
Problem-solving questions in IB Math SL are designed to test far more than formula recall. They assess how well you can understand a situation, translate it into mathematics, and reason logically under exam conditions. These questions reward structure, clarity, and interpretation—not speed alone.
This guide explains a reliable, step-by-step method you can apply to almost any IB Math SL problem, especially multi-part, real-world questions.
What IB Means by “Problem-Solving”
In IB Math SL, problem-solving questions usually:
- Present a real or realistic scenario
- Require multiple mathematical steps
- Combine different topics (e.g. algebra + trigonometry)
- Include interpretation or explanation marks
You are often assessed on:
- Mathematical reasoning
- Communication and notation
- Logical progression from assumptions to conclusions
These are not “one-line answer” questions. How you arrive at the solution matters.
Step 1: Decode the Question Before You Calculate
Rushing into calculations is the most common mistake.
Before doing any maths:
- Read the full question once without writing
- Read it again and identify exactly what is required
- Focus especially on the final sentence—it often determines the method
Pay close attention to command terms such as:
