These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
Lesson details
Key learning points
- In this lesson, we will further develop the knowledge we have gained on symmetry. We will investigate different types of shapes and patterns and use our new knowledge to solve problems based on their lines of symmetry. We will draw, investigate and justify our ideas.
