What students learn in AC9M2SP01
This unit helps students build a clear, usable understanding of Recognise, compare and classify shapes, referencing the number of sides.... 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: recognise, compare and classify shapes, referencing the number of sides and using spatial terms such as “opposite”, “parallel”, “curved” and “straight”.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- sorting a collection of shapes in different ways based on their features such as number of sides, whether all sides are equal, whether pairs of opposite sides are parallel; for example, collections of triangles and other polygons manipulating shapes and recognising that different orientations do not change the shape; for example, cutting out pictures of various shapes, recognising they are they are still classified as the same shape even if they are upside down or on their side
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- Content description: recognise, compare and classify shapes, referencing the number of sides and using spatial terms such as “opposite”, “parallel”, “curved” and “straight”
- E1: sorting a collection of shapes in different ways based on their features such as number of sides, whether all sides are equal, whether pairs of opposite sides are parallel; for example, collections of triangles and other polygons
- E2: manipulating shapes and recognising that different orientations do not change the shape; for example, cutting out pictures of various shapes, recognising they are they are still classified as the same shape even if they are upside down or on their side
- E3: investigating the shapes of different sporting fields, describing and labelling their features including side lines, centre circles and goal squares; for example, labelling the lines on a basketball court and using spatial terms to describe them
- E4: creating regular shapes using digital tools, describing and observing what happens when you manipulate them; for example, dragging or pushing vertices to produce irregular shapes, moving or rotating a shape

- 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.
