Geometry

### Learning Made Easy

Two-dimensional back, front, right, and left views of three-dimensional objects using unit cubes are formed.

### Now You Know

After completing this tutorial, you will be able to complete the following:

• After completing this Activity Object, learners will be able to:
• Draw the 2D views (front, back, top, bottom, and sides) of 3D objects built from unit cubes from different views.

### Everything You'll Have Covered

The Activity Object uses the real-world example of a furniture designer who draws 2D views of 3D furniture models made up of unit cubes.

Provide graph paper and wooden or plastic cubes for students to experiment with building representations of furniture.

The following key vocabulary terms will be used throughout this Activity Object:

• 2D - something have two dimensions (width and length)
• 3D - something having three dimensions (width, length and depth)
• unit cube - a cube with each side measuring one unit long

### Tutorial Details

 Approximate Time 15 Minutes Pre-requisite Concepts Students should know the concept of geometric solids, the difference between 2D and 3D objects. Course Geometry Type of Tutorial Skills Application Key Vocabulary 3D, unit cubes, views of three dimensional objects
