Drawing symmetrical pictures

Use grids and mirrors to complete reflected images.

Quick answer

You can draw symmetrical pictures by folding a piece of paper in half and drawing on one side, or by using a grid or mirror to make sure both sides look exactly the same.

Learning outcome

By the end of this page, you will be able to draw pictures that are exactly the same on both sides of a line, using folding, grids, or mirrors. Success signs:
  • You can spot which side of a shape is the same as the other
  • You can draw a shape and make sure it looks the same on both sides
  • You can use a mirror or grid to help you make a picture symmetrical
  • You can explain what a line of symmetry is

Why this matters

Symmetry is all around us! When you look at a butterfly, a flower, or even your own face, you can see that one side looks like the other side. This idea of balance and matching is important in art, nature, and even in how we build things. Understanding symmetry helps you make better drawings, see patterns, and even solve puzzles. It's a skill that helps you think about how things fit together and look balanced.

How it works

Symmetry means that one side of a shape or picture looks exactly like the other side when you fold it in half or look at it through a mirror. The line that divides the shape into two matching parts is called the line of symmetry. Here’s how to make a symmetrical picture: 1. Choose a shape or picture you want to make symmetrical. 2. Draw a line of symmetry down the middle (this can be vertical, horizontal, or diagonal). 3. Draw half of the picture on one side of the line. 4. Reflect the drawing to the other side using folding, a mirror, or a grid.

Examples you can see

Let’s imagine you are drawing a butterfly. A butterfly has two wings that look the same on both sides. Example 1: Butterfly with a vertical line of symmetry
  • Draw a vertical line down the middle of your paper
  • Draw half of the butterfly on one side of the line (like the left wing)
  • Now, copy the same shape to the other side to match it perfectly
Example 2: Using a grid to make a symmetrical face
  • Draw a grid on your paper (like a 4x4 square grid)
  • Draw one side of a face (like the left eye, nose, and mouth)
  • Copy the same features to the other side using the grid to help
Example 3: Using a mirror
  • Place a mirror along the line of symmetry
  • Draw on one side of the mirror
  • The mirror will show you the reflected image

Try it as a mini adventure

Adventure: Symmetry Detective You are a detective who has found a mysterious drawing in an old book. The drawing is half complete and you must finish it to solve the mystery. You have a mirror and a grid to help you. Step 1: Look at the drawing. What shape is it? Is it a flower, a face, or a house? Step 2: Place a mirror along the line of symmetry to see what the other side should look like. Step 3: Use the grid to help you copy the drawing to the other side. Step 4: Check that both sides match perfectly. Step 5: Once you’ve completed the drawing, you’ll find a secret message!

Common mistakes

  • Mistake: Drawing the wrong side of the picture.
    Why it happens: Not looking carefully at what the other side should look like.
    Fix: Use a mirror or grid to help you see the correct shape.
  • Mistake: Forgetting to draw the line of symmetry.
    Why it happens: Thinking it’s not needed or not understanding what it is.
    Fix: Always draw a line down the middle of your paper to mark where the symmetry is.
  • Mistake: Making the two sides different sizes.
    Why it happens: Not measuring carefully or not copying exactly.
    Fix: Use a ruler or grid to help keep things the same size.
  • Mistake: Drawing the same picture twice without thinking about symmetry.
    Why it happens: Not understanding that symmetry means matching, not copying.
    Fix: Remember that symmetry means one side matches the other, not that you just draw the same thing twice.

Parent and carer guide

Drawing symmetrical pictures is a fun way to help your child learn about balance and patterns. Here’s how you can support them:
  • Start with simple shapes: Begin with easy shapes like butterflies or faces to build confidence.
  • Use mirrors: Let your child use a mirror to see how their drawing looks when reflected.
  • Try grids: Draw a grid on paper and use it to help copy shapes to the other side.
  • Encourage creativity: Let your child choose what to draw, but always check that the sides match.
  • Ask questions: Ask your child to explain how they know their picture is symmetrical.
It’s normal for children to make mistakes at first. Don’t worry if their drawing isn’t perfect – it’s all part of learning! Keep the fun going and keep encouraging them to try again.

FAQ

What is symmetry?

Symmetry means that one side of a shape or picture looks exactly like the other side when you fold it in half or look at it in a mirror.

Can all shapes be symmetrical?

No, not all shapes can be symmetrical. Some shapes, like a scalene triangle, do not have any lines of symmetry.

How do I know if my drawing is symmetrical?

You can check by folding the paper in half, using a mirror, or using a grid to make sure both sides match perfectly.

What are some real-life examples of symmetry?

Examples include butterflies, faces, flowers, buildings, and even your own body!

Why is symmetry important in art?

Symmetry helps make art look balanced and pleasing to the eye. It’s used in paintings, sculptures, and even in nature.
