What students learn in AC9M3SP01
This unit helps students build a clear, usable understanding of Make, compare and classify objects, identifying key features and explaining.... 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: make, compare and classify objects, identifying key features and explaining why these features make them suited to their uses.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- classifying a collection of geometric objects, including cylinders, spheres, prisms and pyramids according to key features such as the shape and number of faces and/or surfaces, edges and vertices making and comparing objects built out of cubic blocks and discussing key features; for example, comparing the amount of space objects occupy by counting how many blocks it takes to build different rectangular prisms that have the same height but different bases
- 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: make, compare and classify objects, identifying key features and explaining why these features make them suited to their uses
- E1: classifying a collection of geometric objects, including cylinders, spheres, prisms and pyramids according to key features such as the shape and number of faces and/or surfaces, edges and vertices
- E2: making and comparing objects built out of cubic blocks and discussing key features; for example, comparing the amount of space objects occupy by counting how many blocks it takes to build different rectangular prisms that have the same height but different bases
- E3: making geometric objects in solid form out of connecting cubes, in skeleton form with straws, and constructing objects using dynamic geometric software, recognising, comparing and discussing the features of the objects using the different representations
- E4: using familiar shapes and objects to build or construct models and compare the suitability of different shapes and objects for aspects of the model; for example, building rectangular towers out of connecting cubes and recognising that the taller the tower, the less stable it becomes unless the base is increased; building bridges out of straws bent into different shapes and comparing the strength of different designs
- E5: identifying, classifying and comparing common objects found on Country/Place as cubes, rectangular prisms, cylinders, cones and spheres
- E6: investigating and explaining how First Nations Australians’ dwellings are oriented in the environment to accommodate climatic conditions (teaching context)

- 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.
