Created by request, this protractor can be photocopied onto film and used as a teaching resource on an overhead projector.
Estimate and compare angles using angle names including acute, obtuse, straight angle, reflex and revolution, and recognise their relationship to a right angle
Identify the relationships between angles on a straight line, angles at a point and vertically opposite angles; use these to determine unknown angles, communicating reasoning
Compare angles and classify them as equal to, greater than, or less than, a right angle
Investigate, with and without digital technologies, angles on a straight line, angles at a point and vertically opposite angles. Use results to find unknown angles

Uses appropriate terminology to describe, and symbols to represent, mathematical ideas
Checks the accuracy of a statement and explains the reasoning used
Identifies, describes, compares and classifies angles
Describes and represents mathematical situations in a variety of ways using mathematical terminology and some conventions
Measures and constructs angles, and applies angle relationships to find unknown angles
Uses grid maps and directional language to locate positions and follow routes
Measures and estimates lengths in metres, centimetres and millimetres
Identifies angles and classifies them by comparing to a right angle
Compares two-dimensional shapes and describes their features
Performs transformations by combining and splitting two-dimensional shapes
Estimates, measures and compares areas using square centimetres and square metres
Measures and constructs angles, and identifies the relationships between angles on a straight line and angles at a point
