Spatial Reasoning Using Cubes

Spatial Reasoning using Cubes and Isometric Drawings
Part Three: Other 2D Representations -- Front-Right-Top

Part Two explored isometric drawings as one way to represent a 3D shape. In this activity you will compare isometric drawing with another type of representation called, a front-right-top view.

Isometric Representation:

Front-Right-Top Representation

Activity 1: Exploring Front-Right-Top Views

TASK 1: Observe the different colors for the corner cubes.

Use the VIEW tool and the Rotation Controls to rotate the shape.

1. What are the Rotation Control settings to see a TOP view?

Turn off the 3D view by clicking on the 3D option. Does your front view match the one shown?

2. Repeat question 1 for a FRONT View and a RIGHT view.

TASK 2:

1. Delete one cube from your picture. What do you notice about the FRONT-RIGHT-TOP view?

2. Continue deleting cubes.

What the fewest number of cubes you can delete to make the front view look different? The right view? The top?

3. Now start over by clicking the "Reload Figure" button.

What is the greatest number of cubes you can delete and still have the FRONT-RIGHT-TOP view look the same as for the original solid?
