Angles

There are 6 different types of angles covered in these A4 charts featuring: Right Angle, Straight Angle, Revolution, Reflex Angle, Acute Angle and Obtuse Angle. They are a great resource for Upper Primary students.

Learning goals

  • We are learning to estimate and compare angles using angle names including acute, obtuse, straight angle, reflex and revolution and recognise their relationship to a right angle.
  • We are learning to compare and classify angles as equal to, greater than or less than a right angle.
  • We are learning to construct angles using a protractor and to estimate, measure and compare angles using degrees and name the angles appropriately, e.g. less than 90o equals an acute angle.
  • We are learning to construct angles using a protractor and to estimate, measure and compare angles using degrees.
  • We are learning to identify, measure, estimate and compare angles on a straight line, angles at a point and vertically opposite angles to find unknown angles.
  • We are learning to identify, measure, estimate and compare angles on a straight line, angle at a point and vertically opposite angles to find unknown angles.
