3. Symmetry
Symmetry is not bilateral symmetry.
Symmetry has 4 main parts
 Lines of Symmetry
 Translation
 Reflection
 Rotation

4. Examples

5. Terminology
Educators make the mistake of saying
mirror image rather than reflection making
students remember and learn incorrect
terminology

6. Symmetry
Symmetry is an easily understood subject
BUT if students learn incorrectly it is
because the educator does not fully
understand the concept as well.

10. Lines of Symmetry

11. Symmetry
 Symmetry is when an
object has two or
more equal sides
when split in half, in
smaller pieces or it is
moved in anyway.
The tiger has 1
line of symmetry .

12. A shape has line
symmetry when one
half of it is the
reflection of the other
half.

13. Symmetry with the Alphabet

14. Symmetry with Shapes

16. Objective
Understand there are three types of lines
of Symmetry
Not ALL objects have a line of symmetry
To have a line of symmetry on objects half
needs to be a reflection of the other half.

17. Conclusion
Educators need to make sure they cover
all aspects of symmetry.
Art is on of the best techniques to teach
children about symmetry.
Make sure to always use the correct
terminology in mathematics especially
symmetry.
