1.0 Standard

… Students identify basic two-dimensional shapes such as triangles, circles and squares and three-dimensional solids and objects such as boxes and balls.

They sort geometric objects according to simple descriptions.

1.25

• Recognition of lines, corners and boundaries in two-dimensional shapes
• Classification of shapes according to number of sides

1.5

• Sorting of objects onto a Venn diagram labelled with shape information

1.75

• Identification of the important features of two-dimensional shapes and use of these distinguishing features to compare and contrast various shapes

2.0 Standard

… Students recognise lines, surfaces and planes, corners and boundaries; familiar two-dimensional shapes including rectangles, rhombuses and hexagons, and three-dimensional shapes and objects including pyramids, cones, and cylinders.

They arrange a collection of geometric shapes, such as a set of attribute blocks, into subsets according to simple criteria, and recognise when one set of shapes is a subset of another set of shapes.

2.5

• Identification of shapes in terms of faces, edges and vertices

3.0 Standard

… Students identify edges, vertices and faces.

3.5

• Classification and sorting of two-dimensional shapes using the properties of lines (curvature, orientation and length) and angles (less than, equal to, or greater than 90°)

4.0 Standard

… Students classify and sort shapes and solids (for example, prisms, pyramids, cylinders and cones) using the properties of lines (orientation and size), angles (less than, equal to, or greater than 90°), and surfaces.
