What Year 8 Maths students should achieve
Coverage is judged against the achievement standard — not by ticking every content description. These are the official Year 8 Maths standard sentences this code builds towards:
- By the end of Year 8, students recognise irrational numbers and terminating or recurring decimals.
- Students use mathematical modelling to solve problems using linear relations, interpreting and reviewing the model in context.
- They conduct statistical investigations and explain the implications of obtaining data through sampling.
- Students use 3 dimensions to locate and describe position.
- They use Pythagoras’ theorem to solve measurement problems involving unknown lengths of right-angle triangles.
- They apply the exponent laws to calculations with numbers involving positive integer exponents.
The Probability progression either side of AC9M8P01
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 7
- AC9M7P01identify the sample space for single-stage events; assign probabilities to the outcomes of these events and predict relative frequencies for related events
- AC9M7P02conduct repeated chance experiments and run simulations with a large number of trials using digital tools; compare predictions about outcomes with observed results, explaining the differences
Builds towards · Year 9
- AC9M9P01list all outcomes for compound events both with and without replacement, using lists, tree diagrams, tables or arrays; assign probabilities to outcomes
- AC9M9P02calculate relative frequencies from given or collected data to estimate probabilities of events involving “and”, inclusive “or” and exclusive “or”
- AC9M9P03design and conduct repeated chance experiments and simulations, using digital tools to compare probabilities of simple events to related compound events, and describe results
Other Year 8 Probability codes
- 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
