Symmetry resources

One of the advantages of digital learning applications is that they often give immediate feedback. Another is that they provide opportunities to ask students to predict and explain their reasoning.

Other immediate feedback for prediction of one (or more) lines of symmetry can result from using varied equipment and settings.

• Cut out and fold pictures (e.g. from magazines) and compare the parts.
• Cut modelling clay or similar and compare the pieces.
• Cut up fruit along lines of symmetry.
• Give students paper shapes and set the challenge of finding all the lines of symmetry. For example, how many ways can any rectangle be cut through the middle? How many ways can a round sponge cake be cut through the middle?
• Use mirrors (or Miras) to explore, draw and describe line and rotational symmetries.
• Create symmetry paintings; for example
  • symmetry paintings for younger students
  • using computer symmetry tools with older students.
