GM2-3: Sort objects by their spatial features, with justification.
Elaboration on this Achievement Objective
This means students will sort objects by selecting an attribute or attributes by which to classify items and allocating the items into groups by commonality of that attribute. At Level Two students should be able to find their own system to classify items, using attributes like shape, colour, size, texture, thickness, material, purpose, etc and justify their allocation of items into categories, for example "all of these shapes have three sides". In doing so students should develop geometric language for attributes such as "side", "corner", "centre", "face", "edge", "curved", "straight", "larger", "smaller", etc.

Level Two
Geometry and Measurement
The purpose of this activity is to support students to sort a set of shapes by the properties of the shapes.
Level Two
Geometry and Measurement
The purpose of this activity is to support students to use their understanding of properties to establish differences and similarities between and among shapes. Similarity is the basis of classifying shapes by their defined properties and difference is important in recognising non-examples.
