What are symmetrical patterns?
Symmetrical patterns are a design or pattern that is the same on both halves when folded. Symmetrical patterns can have one line of symmetry or more. These lines of symmetry may be vertical, horizontal or diagonal.
Symmetrical patterns are a design or pattern that is the same on both halves when folded. Symmetrical patterns can have one line of symmetry or more. These lines of symmetry may be vertical, horizontal or diagonal.
This is an example of a symmetrical pattern with one line of symmetry.
This is an example of a symmetrical pattern with two lines of symmetry.
This is an example of a symmetrical pattern with four lines of symmetry.
Symmetrical patterns are common in many areas of life. Here are some examples of where symmetrical patterns can be found:
1. Architecture - Many Islamic buildings such as mosques feature beautiful symmetrical patterns in their decorations.
2. Fabrics - Many rugs, curtains and items of clothing feature symmetrical patterns.
3. Nature (Animals) - Butterflies are an example of symmetrical patterns that occur naturally. Both wings of a butterfly are identical.
4. Nature (Plants) - Many plants have symmetrical patterns in their flowers and leaves.
4. Tiles - Many tiles used in kitchens, bathrooms and for flooring feature symmetrical patterns.
5. Snowflakes - Snowflakes feature unique symmetrical patterns.
Here are some ways children can be taught about symmetrical patterns:
1. Children can make symmetrical patterns using paints. They can fold a piece of paper in half and then open it out. Then, they can paint a pattern on one half of the paper. If they then press the two halves together, the painted half will make a print on the unpainted half. Opening up the paper again will reveal a symmetrical pattern!
2. Children can be given half of a symmetrical pattern on a grid and asked to complete the pattern so that is is symmetrical. This can be made easier by simplyfying the pattern with just one line of symmetry. Higher ability children can be challenged by making symmetrical patterns that are more complex (e.g. with more than 1 colour) or with more than one line of symmetry.
Here at PlanBee we have created a FREE pack of worksheets that you can use to help your class develop their ability to complete symmetrical patterns.

Here is what the National Curriculum says about symmetrical patterns:
Year 4 (Non Statutory) - Pupils draw symmetric patterns using a variety of media to become familiar with different orientations of lines of symmetry; and recognise line symmetry in a variety of diagrams, including where the line of symmetry does not dissect the original shape.
