Quick summary: During this lesson students calculate experimental two-step probability using observations from their schoolyard. They will consider why certain events are more or less likely to occur and suggest ways to increase the probability of observing particular living things.
This lesson is designed to be taught outside. It contains all the tools required for students to reap the benefits of being outdoors while learning the outcomes of the Australian Curriculum. By spending time outdoors and connecting to nature, students are more likely to care for and conserve nature as adults.
- Students know how to list outcomes of experiments and to list outcomes favourable to an event.
- Students understand how to use relative frequencies to find an estimate of probabilities of ‘and’, ‘or’ events.
- Students recognise that probability is between 0 and 1.
- Students recognise the mental, physical and academic benefits of completing classroom activities outside.

Australian Curriculum Mapping
Year 9 Mathematics
- List all outcomes for two-step chance experiments, both with and without replacement using tree diagrams or arrays. Assign probabilities to outcomes and determine probabilities for events (ACMSP225)
- Calculate relative frequencies from given or collected data to estimate probabilities of events involving ‘and’ or ‘or’ (ACMSP226)
General capabilities: Numeracy, Critical and Creative Thinking.
Cross-curriculum priority: Sustainability OI.2.
Relevant parts of Year 9 Mathematics achievement standards: Students calculate relative frequencies to estimate probabilities, list outcomes for two-step experiments and assign probabilities for those outcomes.
