Properties of Shape - Compare and Order Angles - Presentation

The presentation focuses on the properties of shapes, specifically on how to compare and order angles. The lesson aims to deepen students' understanding of angles by engaging them in various activities. Initially, students are tasked with naming and defining the four types of angles, providing a solid foundation for the topic. Subsequent activities require learners to identify the largest angle in different shapes or diagrams, encouraging them to visually analyse and compare angles. The use of an angle tester is suggested as a tool to assist in ordering angles, which can be a practical way to reinforce the concept of angle measurement.

Further exercises challenge students to order angles from largest to smallest and to categorise them as acute, obtuse, or right angles. These activities are designed to promote critical thinking and reasoning skills, as students must not only identify angles but also compare them relative to each other and to a right angle. Discussion prompts encourage students to use strategies such as comparing angles to a right angle or rotating them to make one of the lines horizontal, which can help in making more efficient comparisons. Independent work includes tasks like drawing clock faces to find angles and ordering them, as well as drawing larger obtuse angles and smaller acute angles, all contributing to a comprehensive understanding of the properties of angles in shapes.
