What Year 9 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 9 Maths standard sentences this code builds towards:
- Students assign probabilities to the outcomes of compound events.
- They determine percentage errors in measurements.
- Students expand binomial products, and factorise monic quadratic expressions.
- They design and conduct experiments or simulations for combined events using digital tools.
- Students apply Pythagoras’ theorem and use trigonometric ratios to solve problems involving right-angled triangles.
- They determine sets of outcomes for compound events and represent these in various ways.

A class can only meet this descriptor if they were taught the one before it. If yours hasn't, that's where the lesson starts — not here.
