Objectives:


Support:

  • Recognise reflection symmetry.
  • Recognise where a shape will be after reflection.
  • Recognise where a shape will be after a translation.

Core:

  • Understand and use the language and notation associated with reflections, translations and rotations.
  • Recognise and visualise the transformation and symmetry of a 2-D shape:
    • reflection in given mirror lines, and line symmetry;
    • rotation about a given point, and rotation symmetry;
    • translation;
  • explore these transformations and symmetries using ICT.
  • Solve word problems and investigate in a range of contexts: shape and space.
  • Suggest extensions to problems by asking ‘What if...?’; begin to generalise and to understand the significance of a counter-example.

Extension:

  • Transform 2-D shapes by simple combinations of rotations, reflections and translations, on paper and using ICT; identify all the symmetries of 2-D shapes.
  • Understand and use the language and notation associated with enlargement; enlarge 2-D shapes, given a centre of enlargement and a positive whole-number scale factor.

Key Vocabulary:

  • shape, mirror line, line / axis of symmetry, reflection symmetry, object, image, congruent, reflect, reflection, horizontal, vertical, coordinates, grid, quadrant, vertices, translate, translation, rotate, rotation, centre of rotation, degree º, direction, transform, transformation.
