What Is Unit 3 About?
Unit 3 Functions is one of the core units in MYP Mathematics Year 5. It builds the algebraic and graphical reasoning skills students need for both the MYP eAssessment and DP Mathematics. Whether you are studying Standard or Extended, this unit develops your ability to model real-world situations, analyse graphs, and solve equations systematically.
Standard vs Extended
The Standard pathway covers the foundations: functions as mappings, linear and quadratic functions, simultaneous equations, and applying these in context. The Extended pathway goes further, introducing transformations of functions, rational functions, linear programming, networks, and a more formal treatment of domain and range.
MYP Criteria in This Unit
- Criterion A – Knowing and Understanding: Solving equations, applying function rules, recall of key properties.
- Criterion B – Investigating Patterns: Spotting relationships in tables and graphs, forming conjectures about function behaviour.
- Criterion C – Communicating: Presenting working clearly, labelling graphs correctly, using correct mathematical notation.
- Criterion D – Applying in Real Contexts: Interpreting gradients, modelling with quadratics or linear systems, optimisation problems.
How to Use These Pages
Navigate to your level — Standard or Extended — and then select individual topic pages. Each page explains what you need to know, common mistakes to avoid, and how to practise effectively for MYP assessments.
