Who Is Standard Level For?

Standard level MYP Maths is designed for students who are developing solid mathematical reasoning without the additional abstract layer required at Extended. Standard Functions still covers rigorous content — you will analyse graphs, solve equations algebraically, and apply mathematics to real contexts — but the scope is carefully defined to build confidence and depth over breadth.

What You Will Study

The Standard pathway for Unit 3 covers:

Assessment Focus

Standard students are assessed across all four MYP criteria. Criterion D problems — where you apply functions to interpret a real situation — appear frequently in this unit. Make sure you can explain the meaning of a gradient or root in context, not just calculate it.

Moving to Extended

If you are considering Extended level, note that the Extended pathway includes all Standard content plus transformations, rational functions, and linear programming. Discuss with your teacher whether a level change is appropriate.

Frequently asked questions

Standard Functions covers the core toolkit: function notation and mapping, linear functions (gradient, intercepts, y = mx + c), solving linear systems, linear modelling, factorising and solving quadratics, the quadratic formula, and graphing parabolas. Left for Extended: composite and inverse functions, transformations of graphs, the discriminant, completing the square as a modelling tool, optimisation with quadratics, and richer mixed linear-quadratic systems.
Standard Functions fits students heading toward DP Mathematics: Applications and Interpretation (AI) at SL, or those still deciding between AI SL and Analysis and Approaches (AA) SL. It is enough for confident handling of linear and quadratic models in real contexts. If your child is aiming for AA SL, AA HL, or AI HL, Standard alone will feel light by Year 5 end. Rule: AI SL-bound, Standard is fine; HL-bound or AA-bound, plan for Extended.
Standard questions are more procedural and scaffolded. You'll see clear prompts like 'find the gradient,' 'solve the system,' or 'factorise and find the roots,' usually with one concept per part. Numbers stay friendly: integer coefficients, quadratics that factorise cleanly, and linear systems with whole-number solutions. Contexts are everyday — phone plans, taxi fares, projectile heights with simple values.
