Properties of Shape - Compare and Order Angles - Planning

In a Year 4 lesson focused on the Properties of Shape, students learn to compare and order angles using practical tools and engaging activities. The lesson starts with a recap of previous knowledge about angles, reinforcing the definitions of obtuse and acute angles, and introduces the concept of ordering angles in both ascending and descending sequences. Key vocabulary such as 'angle', 'obtuse', 'acute', 'right angle', and 'estimate' are emphasised, with resources available to aid understanding. Students are encouraged to use an angle tester along with worksheets and a presentation to aid their learning. They begin by identifying the largest angle in various shapes, using sentence stems to articulate their reasoning and understanding.

As the lesson progresses, students undertake a practical activity where they order a range of angles from largest to smallest, applying their knowledge of angle types. This may involve using an angle tester for verification. The children are also challenged to extend their learning by drawing and correctly positioning their own angles within the sequence. Further activities require students to identify and discuss the properties of different shapes, such as triangles and quadrilaterals, and to determine the odd angle out in a set, explaining their reasoning through partner work. The lesson is structured to cater to different levels of understanding, with worksheets designed to guide students from identifying the largest angle in simple figures to drawing and comparing angles in complex shapes for a deeper level of engagement.
