AC9M6SP01 Year 6 Mathematics

This Content Descriptor from Year 6 Mathematics provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

compare the parallel cross-sections of objects and recognise their relationships to right prisms

Elaborations

• 1 using objects made of foam or polystyrene, slice along different cross-sections, and record the different shapes of faces that result; comparing cross-sections of different objects
• 2 using different pieces of fruit, slicing across different cross-sections, drawing the cross-section; reporting back to the class the results of the investigation
• 3 observing and drawing the shapes resulting from different ways of slicing through familiar objects; for example, slicing carrots at different angles or cutting through playdough models of objects; using playdough models, fruit or similar to establish which objects can be cut in such a way that the cross-section will always be the same shape
• 4 understanding that right prisms are objects where parallel cross-sections to the base of the prism are the same shape and size
• 5 connecting different right prisms to the shape of their parallel cross-sections, such as a triangular prism which can be described as a stack of the same sized triangles, and a cube or square prism, which can be described as a stack of the same sized squares
• 6 investigating the design of First Nations Australians’ dwellings, exploring the relationship between the cross-sections and the dwellings’ construction
