Measurement > Angle

Australian Curriculum Version 9 Says:

Identify angles as measures of turn and compare angles with right angles in everyday situations.

What this means

Students can identify where angles (turns) occur and compare them. Measures of turn does not mean measuring with a protractor.

  • Identify angles; identifying where turning occurs
    e.g. turning a tap on; one full turn.
  • Compare; comparisons are made in terms of quarter, half and three-quarter turns. The term right angle is used and linked to corners.

Tips

  • Protractors are not mentioned until Year 5.
  • Right angles are the most familiar angle to students and are a great benchmark.
  • Try using an angle measure to visualise the turns.
