What students learn in AC9M4SP01
This unit helps students build a clear, usable understanding of Represent and approximate composite shapes and objects in the environment.... 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: represent and approximate composite shapes and objects in the environment, using combinations of familiar shapes and objects.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- identifying common shapes that form part of a composite shape by re-creating these shapes using physical or virtual materials physically or virtually using cubes to make three-dimensional models that approximate real objects; for example, building a virtual environment by using a computer software program to construct objects out of cubes
- 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: represent and approximate composite shapes and objects in the environment, using combinations of familiar shapes and objects
- E1: identifying common shapes that form part of a composite shape by re-creating these shapes using physical or virtual materials
- E2: physically or virtually using cubes to make three-dimensional models that approximate real objects; for example, building a virtual environment by using a computer software program to construct objects out of cubes
- E3: approximating complex shapes and objects in the environment with familiar shapes and objects; for example, drawing cartoon animals by combining familiar shapes
- E4: recognising how familiar shapes and objects are used in logos and other graphics to represent more complex shapes and creating logos using graphic design software
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.

- 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.
