Properties of Shape - Measure with a Protractor (2) - Planning

In a Year 5 summer term lesson on Properties of Shapes, students are tasked with further developing their skills in measuring angles using a protractor. The lesson begins with a refresher on how to accurately use a protractor, with students engaging in partner discussions to explain the process to each other. Key vocabulary such as 'angle', 'degree', 'vertex', and various types of angles are introduced, with resources available to support learning. Students are encouraged to complete 'fluent in four' questions to test their understanding.

The class is then guided through a series of activities that involve identifying and measuring angles. The first activity challenges students to determine the largest angle on a slide and articulate their reasoning. This is followed by a demonstration of correct protractor placement and an opportunity for students to practice measuring angles. A focus on obtuse angles allows students to estimate and measure these, discussing their findings with peers. The lesson includes reasoning activities where students identify and correct mistakes in angle measurement. Differentiated worksheets cater to varying levels of ability, from working towards the expected level to achieving greater depth. The lesson concludes with a reflection on the skills learned, such as estimation and protractor use, and a reminder of common misconceptions to avoid.
