Properties of Shape - Symmetric Figures - Presentation

The lesson on Symmetrical Figures is an engaging exploration of symmetry within shapes, designed to help students identify and complete symmetrical patterns. A key part of the lesson involves a discussion on what constitutes a symmetrical figure, encouraging students to find the root word within 'symmetrical' and understand its meaning. The teaching slides are interactive and prompt students to color squares in order to create symmetrical patterns, fostering a hands-on approach to learning about symmetry in shapes. This visual and practical method of teaching allows students to grasp the concept of symmetry by actively completing patterns to ensure both sides are mirror images of each other.

As part of the lesson, students are presented with a series of activities that challenge them to apply their understanding of symmetry. In the first activity, they color squares to make patterns symmetrical, while subsequent tasks ask them to complete shapes according to a line of symmetry and reflect shapes across a mirror line. These exercises are designed to reinforce the idea that symmetrical figures should have matching sides. The lesson also includes reasoning tasks where students debate statements about symmetrical shapes, such as whether a shape with a symmetrical half will always have double the amount of sides. Independent work further solidifies learning, as students color, complete, and reflect shapes to demonstrate their mastery of symmetrical figures. Discussion prompts throughout the lesson encourage students to articulate their understanding and reasoning about symmetry.
