Geometry, Teacher\'s Edition

(Axel Boer) #1

  • One possible integration is to have the students explore this website and the house designs further.

  • http://www.trendir.com/house-design/

  • Then they can actually work to design their own home using parallelograms.

  • Students can draw this out on grid paper or on plain paper.

  • The key element or focus of the home must be the parallelogram.

  • Have students share their work with their peers.


IV.NotesonAssessment



  • Assessment is completed through observation.

  • Walk around and participate in student groups as they look at the different elements of the house that they
    have been given.

  • Examine each house design.

  • Is the key element a parallelogram?

  • Provide students with feedback on their work.


Proving Quadrilaterals are Parallelograms


I.SectionObjectives



  • Prove a quadrilateral is a parallelogram given congruent opposite sides.

  • Prove a quadrilateral is a parallelogram given congruent opposite angles.

  • Prove a quadrilateral is a parallelogram given that the diagonals bisect each other.

  • Prove a quadrilateral is a parallelogram if one pair of sides is both congruent and parallel.


II.Cross-curricular-Drama



  • Assign students the task of creating a skit to prove that a quadrilateral is a parallelogram.

  • Begin this lesson by reviewing the different characteristics that make a quadrilateral a parallelogram.

  • The synopsis of the skit is “Mr./Ms. Quadrilateral needs to prove that he/she is a parallelogram. He/she has
    selected Geo Geometry to prove the case.”

  • Then let the students go to work.

  • They can use props, scenery (simple) and costumes.

  • Allow time for them to write a skit and rehearse it.

  • Then the students need to be given time to perform their skit.


III.TechnologyIntegration



  • Students can explore the properties of a parallelograms with the following website.

  • http://www.mathwarehouse.com/geometry/quadrilaterals/parallelograms/interactive-parallelogram.php

  • On this website, there is a place where it lists the criteria for proving that a quadrilateral is a parallelogram.

  • Then it also has an interactive part where you can click and drag the vertices of the parallelogram to alter the
    side lengths, angle measures, etc.

  • The numbers change instantly on the screen as you move the vertices around.

  • A great interactive site to work with.


IV.NotesonAssessment



  • Assess each skit.
