What students learn in AC9M4ST01
This unit helps students build a clear, usable understanding of Acquire data for categorical and discrete numerical variables to address.... 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: acquire data for categorical and discrete numerical variables to address a question of interest or purpose, using digital tools; represent data using many-to-one pictographs, column graphs and other displays or visualisations; interpret and discuss the information that has been created.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- investigating many-to-one data displays using digital tools and graphical software, interpreting and discussing key features understanding that data can be represented with one symbol representing more than one piece of data, and that it is important to read all information about a representation before making judgements
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- E1: investigating many-to-one data displays using digital tools and graphical software, interpreting and discussing key features
- E2: understanding that data can be represented with one symbol representing more than one piece of data, and that it is important to read all information about a representation before making judgements
- E3: constructing graphs of data collected through observation during science experiments, recording, interpreting and discussing the results in terms of the scientific study
- E4: co-creating an online poll to survey students in their school about a topic of interest, exploring how online platforms use generative artificial intelligence to make word clouds, quizzes, polls and graphical representations of the collected data
- E5: acquiring samples of data using practical activities, observations or repeated chance experiments, recording data using tally charts, digital tables or spread sheets, graphing, discussing and comparing the results using a column graph
- E6: using secondary data of fire burns to construct data displays that assist First Nations Ranger Groups and other groups to care for Country/Place (teaching context)
How to use this unit

- 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.
