Properties of Shape - Calculating Angles Around a Point - Planning

The lesson on 'Calculating Angles Around a Point' is tailored for Year 5 students as part of their summer term curriculum on Properties of Shapes. It begins with a starter activity that refreshes the students' memory on different types of angles and straight line angles, using visual aids like pictures and angle matching cards. The key teaching point is that the sum of angles around a point is always 360 degrees. Students engage in interactive exercises, such as identifying the number of right angles in various turns and proving their answers. The class then moves on to practical partner work, where they use angle cards to match angles that together make a full turn. The lesson includes true or false games and presentation activities that encourage children to think critically about missing information and how to find missing angles using their knowledge of straight line angles.

Independent learning is facilitated through differentiated worksheets, where children apply what they've learnt to calculate missing angles around a point. The lesson also incorporates reasoning activities that prompt students to use precise vocabulary and demonstrate their understanding of the total angles around a point. The plenary session focuses on reinforcing the day's learning outcomes, with a 'Give me five' reflection technique that covers what they've learnt, the skills used, any difficulties encountered, and what they will remember for future lessons. Depending on their level of understanding, students are challenged with finding one or two missing angles around a point, with the most advanced students using given statements to aid their calculations. The lesson is designed to clarify common misconceptions, such as errors in addition and subtraction and confusion between types of turns and their corresponding degrees.
