Properties of Shape - Calculate Angles - Worksheet

The "Calculate Angles" worksheet is an educational resource designed to help Year 6 students master the concept of angles. The National Curriculum objective for this lesson is for students to recognise angles where they meet at a point, on a straight line, or are vertically opposite, and to find missing angles. To support this learning, differentiated sheets and teaching slides are provided as resources. The key vocabulary includes terms such as angle, right angle, obtuse, acute, whole, and straight line. Students are expected to apply their understanding of these concepts to calculate missing angles, and they should be able to recognise and identify right angle notation on diagrams.

During the lesson, children will engage in writing number sentences based on angles shown in pictures and will find missing angles using the measures of some given angles. The tasks involve simple to more complex diagrams, with varying levels of difficulty to cater to different learning stages from working towards, working within, to greater depth. Key questions prompt students to think about the relationships between the given angles and the angle facts needed to solve the problems. The worksheet includes reasoning and problem-solving activities, such as calculating angles around a point, interpreting pie charts to determine the size of angles representing car sales data, and working out equal angles when several meet at a point on a straight line. Answers are provided for students to check their work and understand the logic behind the calculations.
