Representing Solids
I.SectionObjectives
- Identify isometric, orthographic, cross- sectional views of solids.
- Draw isometric, orthographic, cross- sectional views of solids.
- Identify, draw and construct nets for solids.
II.MultipleIntelligences
- Make this lesson very interactive by giving students the following hands- on tasks.
- Students may work in small groups for this activity.
- In the activity, be sure that students have graph paper, dot paper, plain paper, rulers, tape and colored pencils.
- Students are going to choose a solid to work with. You can provide students with a model of a solid if you
have them. - Then students are going to create four different things.
- Create an orthographic projection of their solid.
- Create a cross- section of the solid.
- Create a net for the solid.
- Use the net to create an actual model of the solid.
- Intelligences- linguistic, visual- spatial, bodily- kinesthetic, logical- mathematical, interpersonal, intraper-
sonal.
III.SpecialNeeds/Modifications
- Review polyhedral.
- Review faces, edges and bases.
- Define isometric.
- Define perspective.
- Define orthographic projection.
- Define cross- section.
- When students draw an orthographic projection, they will need the following views:
- Top
- Left side
- Back
- Right side
- Front
- Bottom
IV.AlternativeAssessment
- An assessment of student understanding can easily be completed by looking at the student work.
- Were the students able to create a net that built a solid?
- Did they use the same solid for all of the pieces of the activity?
- Where did students have challenges?
