Curriculum content descriptions

estimate, construct and measure angles in degrees, using appropriate tools including a protractor, and relate these measures to angle names (AC9M5M04)

Elaborations
  • using a protractor to measure angles in degrees and classifying these angles using angle names; for example, an acute angle is less than \(90\)°, an obtuse angle is more than \(90\)° and less than \(180\)°, a right angle is equal to \(90\)° and a reflex angle is more than \(180\)° and less than \(360\)°
  • estimating the size of angles in the environment using a clinometer and describing the angles using angle names
  • using a ruler and protractor to construct triangles, given the angle measures and side lengths
  • using a protractor to measure angles when creating a pattern or string design within a circle
  • recognising the size of angles within shapes that do and do not tesselate, measuring the angles and using the sum of angles to explain why some shapes will tesselate and other shapes do not

Angle estimator

This is an interactive resource containing two activities about estimating and measuring angles. In the angle estimation activity, users can select acute, obtuse or reflex angles, or any angle between zero and 360 degrees. In the angle drag activity, one arm of the angle can be dragged to rotate around the vertex, creating ...

Angles are the primary structural component of many shapes Multi-age 3–6 Year B – Unit 10

This 2-week unit unit develops the big idea that angles are the primary structural component of many shapes. Students are provided opportunities to: measure, compare and sequence events by halving and quartering blocks of time; represent fractional quantities of time and the multiplicative relationships; estimate and describe ...
