Geometry, Teacher\'s Edition

• Identify isometric, orthographic, cross- sectional views of solids.


• Draw isometric, orthographic, cross- sectional views of solids.


• Identify, draw and construct nets for solids.

II.ProblemSolvingActivity-Solids

• If you used the activity in the Differentiated Instruction lesson of the Teacher’s Edition, you can move right
  on to the second part of this activity.


• If not, then begin with this part.


• Part One- Give students a geometric solid to work with.


• Then students are going to create four different things.


• 
  
  
  
  1. Create an orthographic projection of their solid.
  
  
  
  


• 
  
  
  
  2. Create a cross- section of the solid.
  
  
  
  


• 
  
  
  
  3. Create a net for the solid.
  
  
  
  


• 
  
  
  
  4. Use the net to create an actual model of the solid.
  
  
  
  


• Part Two- students are going to use the net that they created to design a mobile of solids.


• For this, students can create the same solid in different sizes, or they can create nets for different solids.


• Encourage students to use color and creativity in their mobile.


• Students can connect all of the created solids together with string and wooden dowels.


• Have materials on hand for students to complete their mobiles when finished.


• You can create a great display of mobiles and hang them all around the classroom.

III.MeetingObjectives

• Students will identify isometric, orthographic, cross- sectional views of solids.


• Students will draw isometric, orthographic, cross- sectional views of solids.


• Students will identify, draw and construct nets for solids.


• Students will show their work in a mobile.

IV.NotesonAssessment

• Look at each mobile and assess it.


• Are the nets created correctly?


• Did the student use different sized versions of the same solid or different solids?


• Is the mobile finished?


• Did the student use color and creativity in his/her design?

Prisms

I.SectionObjectives

• Use nets to represent prisms.


• Find the surface area of a prism.


• Find the volume of a prism.

II.ProblemSolvingActivity-PrismPair-Up

• This activity requires some preparation.


• First, you will need a bunch of boxes.
