GM1-2: Sort objects by their appearance.

The Ministry is migrating nzmaths content to Tāhurangi.           
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz). 
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024. 
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

Elaboration on this Achievement Objective

This means students will classify or sort objects by their characteristics. These characteristics include shape, size, colour, texture, weight, and temperature. Students should be able to justify why they have sorted objects in the way they have and be encouraged to develop increasingly sophisticated classifications such as shape and size.

Arty Shapes

Level One
Geometry and Measurement
Units of Work
In this unit ākonga participate in a variety of art based activities to develop their knowledge of 2-dimensional shapes. They use their own language to describe their works and the shapes they have used.
  • Name 2-dimensional shapes: triangle, square, oblong (non-square rectangle), circle, oval and diamond.
  • Describe shape attributes (sides, corners, curved and straight lines, edges, pointed) in their own language.

New Kids on the Block

Level One
Geometry and Measurement
Units of Work
This unit draws on students' knowledge of local buildings and asks them to construct buildings. In turn, teachers are provided with opportunities to observe and listen to students' use of topic-specific language. Using blocks is a powerful medium for improving students' perception of objects and...
  • Classify shapes into categories.
  • Discuss differences and likenesses of the shapes.
  • Explore, experiment and talk about the form and function of the shapes in their own language.

Odd one out

Level One
Geometry and Measurement
Problem solving activities
This problem solving activity has a geometry focus.
  • List a number of properties that distinguish squares from circles from cubes from pentagons.
  • Devise and use problem solving strategies to explore situations mathematically (make a drawing, use equipment).

Play dough

Level One
Geometry and Measurement
Units of Work
In this unit students develop number, measurement, and shape understandings, skills and language, through making and working with play dough in a technology context.
  • Sort shapes by their appearance.
  • Justify the classification of shapes using geometric language
  • Identify the differences between 2D and 3D shapes.
  • Recognise that two-dimensional shapes are flat and have no ‘thickness’.
  • Use non-standard units to measure capacity.
  • Recognise that shapes with three dimensions300

Quadrominoes

Level One
Geometry and Measurement
Rich learning activities
The purpose of this activity is to engage students in finding similarities and differences between shapes.

Shape Explorers

Level One
Geometry and Measurement
Units of Work
In this unit students identify and describe the attributes of 2D shapes (i.e. sides and corners). They apply this knowledge to classify shapes by name, number of sides and corners, and to describe the similarities and differences between shapes.
  • Use the language ‘side’ and ‘corner’ in describing shapes.
  • Classify 2D shapes according to how many sides they have.
  • Identify 2D shapes by name.

Shape Makers

Level One
Geometry and Measurement
Units of Work
In this unit ākonga describe and classify 2D and 3D shapes. They will use their own language in their descriptions, will explore similarities and differences, and will informally consider sides, corners, curved and straight lines.
  • Sort, compare and classify 2D and 3D objects such as triangle, square, oblong, circle, box, cylinder and sphere.
  • Describe shape attributes in their own language.
