IB Math AI 2.6 - Developing Models

This IB Math AI SL 2.6 – Developing Models slide deck provides an engaging and visual introduction to the process of creating, testing, and refining mathematical models.

It guides students through the full modelling cycle, from posing a real-world problem and selecting an appropriate model to validating results and evaluating reliability. The lesson includes clear explanations of independent and dependent variables, interpolation versus extrapolation, and step-by-step examples using linear and quadratic regression on the GDC.

Real-world applications, such as heating experiments and the Sydney Harbour Bridge, illustrate how models are formed and adjusted based on data. Designed for active classroom use, this resource helps students build confidence in identifying, justifying, and interpreting mathematical models while preparing them for applied modelling tasks in IB assessments.
