Measurement > Angle

Australian Curriculum Version 9 Says:

Estimate, construct and measure angles in degrees, using appropriate tools including a protractor, and relate these measures to angle names.

What this means

Use angle language, such as acute, right and obtuse when talking about angles. Make and measure angles using a ruler and protractor.

  • This is the first mention of protractors.

Tips

  • Students need to know benchmark angles of 90, 180 and 360 degrees.
  • Use a full 360 degree protractor rather than the 180 degree half protractor.
    There will be less problems mistaking 60 degrees for 120 degrees.
