• Materials and resources:
  Lesson Materials:
  envelopes
  rulers
  tape
  glue sticks
  scissors
  calculators
  colored pencil
  straws
  cotton twine
  tissue paper
  
  Lesson Resources:
  Surface Area Worksheet

• Technology resources:
  Internet Explorer, PowerPoint, Word, VRML (Virtual Reality Modeling Language), Cortona, Text Pad, Projector
  
  
• The number of computers required is 1 per student.
• Students Familiarity with Software Tool:
  1.) Internet Explorer- Basic internet browser that students typically use on a daily basis.
  
  2.) Power Point- A program used to create presentations that most students have utilized in the classroom in some form whether it be viewing or creating.
  
  3.) Microsoft Word- A basic document creation program utilized by most students through home use and in the academic realm.
  
  4.) VRML- A virtual reality modeling language that can be used to create 3-dimensional images that may be manipulated via the various coding process. Although the students may be familiar with the programs possible outcomes from television animation and the various type of electronic/computer games, students will typically be an uninformed group that do not possess a background in this programming language.
  
  
• Implementation:
  1.) Internet Explorer- Internet browser utilized to research information in regards to the module topic and will be available as a hyperlink in power point presentation as a reference.
  
  2.) Power Point- Used to direct students to pertinent information regarding the topic & instructions during the demonstration of how to construct a tetrahedron kite.
  
  3.) Microsoft Word- A word processing program that will be used to create student handouts.
  
  4.) VRML- Program will be implemented by creating a VRML code that will show students how to construct tetrahedron kites by looping a ste-by-step process of a tetrahedronal kites construction.
