This PowerPoint lesson introduces the concept of lines of symmetry to visual, audio, and kinesthetic learners. It defines symmetrical and asymmetrical shapes, noting that some shapes can have multiple lines of symmetry. Examples are provided of symmetrical shapes like squares and rhombus, as well as asymmetrical shapes like hearts. Students participate in hands-on activities to identify symmetrical and asymmetrical objects and draw complementary shapes by folding paper.

2. Lines of Symmetry

4. What are Lines of Symmetry?
A shape is symmetrical when a line can be drawn
through it, so that both sides of the line look
exactly the same.

5. When an object has symmetry, we say that it
is Symmetrical.

6. When an object does not have symmetry,
we say it is Asymmetrical.

7. Shapes can have more than one line of
symmetry.
This square has four lines of symmetry.

8. This rhombus has lines of
symmetry.

9. This heart has one line of symmetry.

10. Let’s Play Symmetry Sort!
Can you tell which objects are symmetrical and which are
asymmetrical?

11. Hands On Activity!
1. Select a partner to work with.
2. Each person fold a paper in half.
3. One student has to draw a simple shape or object on one
side of the paper. Their partner has to complete the
shape on the other side of the fold.
4. It is now the other partner’s turn to draw.
