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

In this Year 2 lesson on lines of symmetry, children will delve into the concept of symmetry through engaging and practical activities. The lesson starts with a discussion on vertical symmetry, where students explore how a shape can be split into two identical halves from top to bottom. With the aid of mirrors, coloured pencils, and rulers, students will work in small groups, using real-life objects and 2D shapes to investigate and find vertical lines of symmetry. The lesson aims to equip children with the ability to identify and draw lines of symmetry on various shapes and understand the concept of reflection. More advanced students will be challenged to accurately complete more complex shapes, enhancing their understanding of symmetry in a broader context.

Throughout the lesson, differentiated worksheets will be used to cater to varying levels of understanding, from basic fluency to greater depth. Students will engage in reasoning activities, both individually and as a class, to identify and correct mistakes, and to draw their own shapes with vertical symmetry. Key questions will prompt students to think about the nature of symmetry and how to recognise it in different shapes. Common misconceptions are addressed, such as confusing reflection with repetition, and the lesson emphasises accurate use of tools like rulers and mirrors. The session wraps up with a reflective exercise where students articulate what they've learned, the skills they've used, and what they found challenging, ensuring a thorough understanding of symmetry and its properties.
