Elaboration on this Achievement Objective

This means students will physically carry out translations, reflections, and rotations on shapes and discuss what patterns they see. Translations are shifts of a shape along a line, for example repeating a potato print across the top border of a page. Reflections are images of a shape as though it is reflected in a mirror. Rotations are turns, so when an object is turned about a point, either inside or outside of itself, the image is a rotation of the original shape. At level one rotations can be described as fractions of a full turn, for example half and quarter turns.

Making Patterns

Level One
Geometry and Measurement
Units of Work
In this unit students explore patterns involving transformations of shapes. Students make and identify patterns that involve translation, reflection, and rotation. They make their own patterns and pictures to show the transformations, and discuss with others how they included the different...
  • Make patterns that involve translations, reflections, and rotations.
  • Identify translations, reflections, or rotations in patterns.

Pattern Matching

Level One
Geometry and Measurement
Units of Work
In this unit students explore lines of symmetry in pictures, shapes and patterns and use their own words to describe the symmetry.
  • Identify lines of symmetry in objects.
  • Make patterns which have line symmetry.
  • Describe line symmetry in their own words.

The Transformations of Spring

Level One
Geometry and Measurement
Units of Work
The purpose of this unit is for students to investigate the transformation elements of geometry in spring flowers. They apply these elements to create artworks.

  • Sort flowers by their appearance.
  • Explain and justifying groupings with reference to attribute language.
  • Recognise and describe reflection.
  • Recognise and describe symmetry.
  • Recognise and describe rotation.
  • Recognise and describe translation.
