Geometry, Teacher\'s Edition

(Axel Boer) #1

  • Use an example so that students understand symmetry in connection with trapezoids.


IV.AlternativeAssessment



  • Collect student diagrams.

  • Assess understanding based on labels and statements.


Kites


I.SectionObjectives



  • Identify the relationship between diagonals in kites.

  • Identify the relationship between opposite angles in kites.


II.MultipleIntelligences



  • Write out the following notes on kites.



    1. No parallel sides.





    1. Two pairs of congruent sides adjacent to each other.





    1. Two vertex angles





    1. Two non- vertex angles that are congruent





    1. Diagonals are perpendicular



  • Have students design a kite on a coordinate grid.

  • They must prove it is a kite by providing proof that the diagonals are perpendicular, and that the non- vertex
    angles are congruent.

  • They can do this through statements or by writing a proof with reasons.

  • Finally, once their diagram has been approved, they can use it to design and decorate their own kite. Students
    can use chart paper and colored pencils to do this.

  • Hang all work up in the class.

  • Intelligences- linguistic, logical- mathematical, visual- spatial, bodily- kinesthetic, interpersonal, intraper-
    sonal.


III.SpecialNeeds/Modifications



  • Define adjacent.

  • Define vertex angles.

  • Define non- vertex angles.

  • Walk through each proof.

  • Explain each “Reason” in the proof.


IV.AlternativeAssessment



  • Approve all students kite diagrams before students design their final kite.

  • Be sure that the points have been successfully proven.
