Symmetry

  1. 1. Symmetry By Jennifer Gomez
  2. 2. Real face Two left sidesTwo right sides
  3. 3. Symmetry Symmetry is not bilateral symmetry. Symmetry has 4 main parts  Lines of Symmetry  Translation  Reflection  Rotation
  4. 4. Examples
  5. 5. Terminology Educators make the mistake of saying mirror image rather than reflection making students remember and learn incorrect terminology
  6. 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. 7. Difficult Examples
  8. 8. 1st Technique
  9. 9. 2nd Technique
  10. 10. Lines of Symmetry
  11. 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. 12. A shape has line symmetry when one half of it is the reflection of the other half.
  13. 13. Symmetry with the Alphabet
  14. 14. Symmetry with Shapes
  15. 15. JENNIFER
  16. 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. 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.
