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:
- Introduction to Functions – mapping diagrams, function notation, domain and range, the vertical line test
- Linear Functions – gradient, y-intercept, graphing straight lines in the form y = mx + c
- Linear Systems – solving simultaneous equations graphically and algebraically
- Linear Relationships – interpreting gradient and intercept in real-world contexts (Criterion D)
- Quadratic Equations – solving by factorisation, the quadratic formula, and completing the square
- Quadratic Equations and Functions – connecting equations to parabola graphs, vertex, and roots
- Quadratic Equations in 2D – applying quadratic reasoning to two-dimensional geometry problems
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.
