Learning goals
- 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.
