Lesson 8 In this lesson, children explore the interior angles in different quadrilaterals to learn that the angles in all quadrilaterals total 360 degrees. They will learn that different quadrilaterals have different angle properties. They use their knowledge of angles to find missing angles in quadrilaterals. There is a teaching presentation accompanied by differentiated activities with a range of fluency, reasoning and problem-solving questions. Year 6 Mathematics Content Descriptors V8.4 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 ACMMG141 V9 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 AC9M6M04 Differentiation: There are three levels of differentiation in this pack: ‘working towards,’ ‘expected’ and ‘greater depth’.
