Properties of shape - Lines of symmetry draw the whole - Worksheet

The worksheet titled "Lines of Symmetry – Draw the Whole" is designed to help Year 6 children understand and apply the concept of symmetry, particularly focusing on identifying the vertical line of symmetry in two-dimensional shapes. To facilitate this learning, a variety of resources are provided, including a teaching presentation, worksheets, mirrors, coloured pencils, rulers, a selection of 2D shapes, and real-life objects to observe. The key vocabulary for the lesson includes terms such as symmetry, lines, reflection, vertical, half, whole, diagram, and shape. Students are tasked with completing the other half of partially drawn shapes by using the pre-drawn line of symmetry as a guide. They also learn to reflect shapes across a vertical line of symmetry and identify which shapes possess this type of symmetry. For those working at greater depth, the challenge is extended to more complex shapes, and they are encouraged to draw the lines of symmetry themselves.

In the reasoning and problem-solving section of the worksheet, students are prompted to identify and correct mistakes in symmetry drawings and to demonstrate their understanding by creating their own symmetrical shapes. For example, they are asked to evaluate statements such as "A square has a vertical line of symmetry," and to draw shapes that exhibit vertical symmetry, including real-life objects. The worksheet encourages critical thinking by having children investigate whether all triangles have vertical lines of symmetry, challenging common misconceptions. This task not only reinforces their knowledge of geometric principles but also sharpens their analytical skills as they explore symmetry in various contexts.
