Properties of Shape - Lines of Symmetry - Worksheet

The lesson on Lines of Symmetry is tailored for students to explore and identify symmetry in two-dimensional shapes, with a focus on understanding how shapes can be symmetrical in various orientations. The National Curriculum objective is for students to be able to pinpoint lines of symmetry in 2D shapes, regardless of how they are presented. To facilitate this learning, differentiated worksheets are provided as resources. The vocabulary for the lesson includes terms such as "lines of symmetry" and "2D shapes". Students are encouraged to use mirrors and tracing paper to assist in finding the lines of symmetry, and paper folding activities are suggested as a practical method to demonstrate the concept of symmetry.

Throughout the lesson, students are prompted with key questions to deepen their understanding, such as asking for real-life examples of symmetry, discussing whether lines of symmetry must always be vertical, and considering how the orientation of a shape affects its lines of symmetry. The children will engage in sorting activities, placing shapes into tables based on the number of lines of symmetry they possess. They will also delve into reasoning and problem-solving tasks, such as drawing symmetrical shapes using a set number of squares and debating statements about the symmetry of shapes, including triangles and six-sided figures. These exercises aim to reinforce their knowledge and challenge their understanding of symmetry in shapes.
