Design and conduct repeated chance experiments and simulations, using digital...: Year 9 Maths topic guide

design and conduct repeated chance experiments and simulations, using digital tools to compare probabilities of simple events to related compound events, and describe results

What students learn in AC9M9P03

This unit helps students build a clear, usable understanding of Design and conduct repeated chance experiments and simulations, using digital.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.

  • Start with the main idea: design and conduct repeated chance experiments and simulations, using digital tools to compare probabilities of simple events to related compound events, and describe results.
  • Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
  • using digital tools to conduct probability simulations that demonstrate the relationship between the probability of compound events and the individual probabilities comparing experiments which differ only by being undertaken with replacement or without replacement
  • Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

Curriculum coverage and elaborations

The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.

  • Content description: design and conduct repeated chance experiments and simulations, using digital tools to compare probabilities of simple events to related compound events, and describe results
  • E1: using digital tools to conduct probability simulations that demonstrate the relationship between the probability of compound events and the individual probabilities
  • E2: comparing experiments which differ only by being undertaken with replacement or without replacement
  • E3: conducting two-step chance experiments using systematic methods to list outcomes of experiments and to list outcomes favourable to an event
  • E4: using repeated trials of First Nations Australian children’s instructive games; for example, Gorri from all parts of Australia, to calculate the probabilities of winning and not winning (teaching context)

How to use this unit

Read the topic guide, use the teacher slide for instruction, then complete the Worksheet, Practice and Test. These three activities use the same eight-question unit bank.

Common mistakes to watch for

  • Rushing to a rule before checking the concrete model, drawing or number sentence.
  • Using the correct answer once but not being able to explain why it works.
  • Mixing up similar vocabulary such as more/less, before/after, longer/shorter or equal groups/sharing.
