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.
The Probability progression either side of AC9M9P02
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.
Taught before · Year 8
- AC9M8P01recognise that complementary events have a combined probability of one; use this relationship to calculate probabilities in applied contexts
- AC9M8P02determine all possible combinations for 2 events, using two-way tables, tree diagrams and Venn diagrams, and use these to determine probabilities of specific outcomes in practical situations
- AC9M8P03conduct repeated chance experiments and simulations, using digital tools to determine probabilities for compound events, and describe results
Builds towards · Year 10
Other Year 9 Probability codes
- AC9M9P01list all outcomes for compound events both with and without replacement, using lists, tree diagrams, tables or arrays; assign probabilities to outcomes
- AC9M9P03design and conduct repeated chance experiments and simulations, using digital tools to compare probabilities of simple events to related compound events, and describe results
