Properties of Shape - Calculate Angles - Planning

The Year 6 summer term lesson on 'Properties of Shape' focuses on enhancing students' ability to calculate angles. The National Curriculum objectives covered include recognising angles at a point, on a straight line, and vertically opposite ones, as well as drawing shapes with specific dimensions and angles. Students compare and classify geometric shapes, and find unknown angles in various polygons. Key vocabulary such as 'angle', 'measuring angles', 'right angle', 'obtuse', 'acute', 'reflex', and 'protractor' are introduced, alongside concepts of turns and lines. The lesson encourages children to complete four questions to test their fluency, and they can access vocabulary cards and definitions for assistance.

The lesson begins with a recap of previous learning, where students apply their understanding of angles in different contexts to calculate missing angles. Through a series of activities, they explore angles on a straight line and around a point, using expressions and number sentences to find the values of unknown angles. For instance, they learn that the sum of angles on a straight line equals 180° and the sum around a point equals 360°. Group work and differentiated worksheets are used to deepen understanding and address any misconceptions. The lesson concludes with a reflection session where students consider what they have learned, the skills they used, and what they found challenging, ensuring they remember the key points of the lesson. Differentiated learning outcomes cater to varying levels of proficiency, from writing simple number sentences to solving complex diagrams with multiple missing angles.
