This unit covers estimating, measuring, drawing and calculating angles. Students describe, classify and identify types of angles using clear vocabulary, and measure and draw angles accurately. Students revise facts involving angles around a point, angles at a point on a straight line and vertically opposite angles from experiences in primary school. Students will begin to generalise these angle facts. Students explore and clarify definitions of parallel lines and perpendicular lines, and use rules around corresponding, alternate and allied angles. This will be built upon and applied in the following unit when exploring properties of quadrilaterals. Students being to formulate equations to show relationships between angles using the angle facts that are introduced in this unit. This is first done numerically before introducing unknown angles. Through this, students begin to solve equations with one unknown. |

Comparing and classifying angles Estimating angles. Using a protractor to measure angles Use a protractor to draw angles Find missing angles that partition a known angle. Introduce the vocabulary of ‘vertically opposite’ angles Understand properties of parallel lines. Explore intersections formed with two lines and a transversal. Understand and identify vertically opposite angles. Identify alternate angles. Understand equality of alternate angles for parallel lines. Understand and identify allied angles. Understand and identify corresponding angles |
