You will need paper, a pencil, and scissors for these activities.
Exploring one line of symmetry
1 Take a piece of rectangular paper and fold it in half.
2 Draw a design on the sheet of paper from the fold edge. You should keep as much of the fold edge as you can.
3 Write “Cut out” on the part you will cut out (see the diagrams below) and then cut it out.
4 Open to reveal your symmetric pattern.
The fold line for this symmetric shape is called the mirror line or line of symmetry.
The shape has symmetry because you can fold it exactly in half.
Each half is a mirror image of the other half.
