The Polyhedron


I.SectionObjectives



  • Identify polyhedral.

  • Understand the properties of polyhedral.

  • Use Euler’s formula to solve problems.

  • Identify regular (Platonic) polyhedral.


II.Cross-curricular-CubicHouses



  • Use the following image from the Wikipedia website.

  • This is Figure 11.01.01

  • http://www.en.wikipedia.org/wiki/File:Rotterdam_Cube_House.jpg

  • Use the image of the cubic houses to conduct a discussion with the students about the different parts of the
    polyhedron.

  • Students should be able to identify some of the edges, the vertices and the faces of the cubes.

  • Have the students identify what is unique about these houses.

  • Brainstorm a list and write them on the board.

  • When finished, have the students move on to drawing their own design of a cubic house.

  • Have them label the faces, edges and vertices of their house design.


III.TechnologyIntegration



  • Have students select one specific polyhedron to research.

  • Then have them research this polyhedron as it is connected to a theme such as photography, architecture or
    nature.

  • Ask the students to keep track of the websites that they visit.

  • Have the students take notes on where and how they discover their specific solid.

  • Then have them share their findings in small groups.


IV.NotesonAssessment



  • Assess student work through their house design.

  • Did the students identify the faces, edges and vertices?

  • Were the students creative in their design?

  • Also look at the technology integration section.

  • Did the students find examples of their solid according to theme?

  • Were any of the results surprising?

  • Assess student understanding through their sharing.
