  • 1. Symmetry By Jennifer Gomez
  • 2. Real face Two left sidesTwo right sides
  • 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.
  • 7. Difficult Examples
  • 8. 1st Technique
  • 9. 2nd Technique
  • 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
  • 15. JENNIFER
  • 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.
