Lesson 5a - Volume of Prism - Build-Up & Decompose

This lesson uses a series of silent screencasts. Click on the images to start the screencasts.

Learning Objectives:
Understand why the volume formula for a prism is length*width*height, by building a prism.
Use the group, explode, copy, paste, move, entity information (volume), and dimension tools.
Common Core State Standards - Mathematics - 6.G.2

Task A. Watch and discuss the first five screencasts by clicking on the graphic.
Task B. Outline the steps that were used (repeatedly) in SketchUp to create the 3 x 4 x 4 meter prism.
Task C. Have students work on small groups or pairs to design their own prism using the build-up method.
Modification - Kinesthetic learners (of any age) will need to have cubes to arrange on their desk or table.
Task D. Watch the LAST screencast "DecomposePrism" and discuss this method of "seeing" the unit cube.
