Elaborations
- • Elaboration 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°
- • Elaboration estimating the size of angles in the environment using a clinometer and describing the angles using angle names
- • Elaboration using a ruler and protractor to construct triangles, given the angle measures and side lengths
- • Elaboration using a protractor to measure angles when creating a pattern or string design within a circle
- • Elaboration 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
