This IB Math AI SL 2.5 – Modelling with Functions lesson introduces students to the use of linear, quadratic, exponential, cubic, and sinusoidal models to represent real-world situations.
It explains how mathematical functions can describe relationships between variables in contexts such as physics, economics, and biology, while emphasizing the interpretation of key features like intercepts, asymptotes, amplitude, and rate of change. Students learn to distinguish between direct and inverse variation and apply appropriate models to solve practical problems, including cost estimation, population growth, and periodic motion.
The PowerPoint slide deck has visual representations, as step-by-step practice tasks that use both algebraic and technological approaches. Fully aligned with IB Math AI SL Topic 2.5, this resource helps students build fluency in constructing, analyzing, and evaluating mathematical models for real-world data in preparation for both assessments and further study.

Great! Removed radians for AI SL and included some more information about how to find the period in the sinusoidal model example but a solid starting point for teaching modelling
