Symmetry is not bilateral symmetry.Symmetry has 4 main parts

Terminology

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

Page 6: Symmetry

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.

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 .

Page 12: Symmetry

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

Objective

Understand there are three types of lines of Symmetry

Not ALL objects have a line of symmetryTo have a line of symmetry on objects half

needs to be a reflection of the other half.

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.
