## How do you teach symmetrical shapes?

Once students touch on the idea that the wings match in some way, introduce the word “symmetry.” Explain that something has symmetry if it can be split into two mirror-image halves. For example, a butterfly is symmetrical because you can fold a picture of it in half and see that both sides match.

**What is the shape of symmetry?**

Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing line (a mirror line) can be drawn on it, to show that both sides of the shape are exactly the same.

### What do we learn from symmetry?

Symmetry is a fundamental part of geometry, nature, and shapes. It creates patterns that help us organize our world conceptually. We see symmetry every day but often don’t realize it. People use concepts of symmetry, including translations, rotations, reflections, and tessellations as part of their careers.

**Why is symmetry so important?**

#### Why is symmetry useful?

Symmetry creates balance, and balance in design creates harmony, order, and aesthetically pleasing results. It is found everywhere in nature, and is probably why we find it to be so beautiful. Asymmetry is a break in symmetry, which when used effectively, can make things more interesting.

**How to recognize a line of symmetry in a shape?**

Folding a two-dimensional shape can help a student identify the lines of symmetry. Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

## How to teach symmetry in a science class?

Students will be able to identify symmetrical figures, draw lines of symmetry, and explain why or why not a figure has symmetry. Display the image of the butterfly. Ask the class to share some things they notice about the image. Some guiding questions you could ask are: What are the colors of the butterfly’s wings? How are the wings shaped?

**How to draw a line of symmetry in 4th grade?**

Use appropriate tools strategically. In today’s lesson, the students learn to recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Also, the students identify line-symmetric figures and draw lines of symmetry (4.G.A3).

### Which is an example of symmetry in math?

For example, a butterfly is symmetrical because you can fold a picture of it in half and see that both sides match. Let your students know that the next activity will involve using a mirror to check figures for symmetry. Model the checking process before having students begin the activity.
