Introduction
Did you know the world is filled with geometric solids? Buildings, bridges, and automobiles have all been designed using geometric solids. Even our planet is a geometric solid! Do you know the name of this solid? This exercise will help you better understand these unique and important shapes. In a few minutes you will have the opportunity to work with text, graphics, electronic geo-boards, and electronic manipulatives to become a master of geometric solids. Who knows, someday you might be using these geometric solids to design your own car or house.

The number of edges
The number of vertices

4. Goal and Objectives Goal Objectives
The student will be able to identify geometric solids and their characteristics, including the faces, edges, and vertices.
Objectives
When provided with appropriate links, the student will be able to identify the characteristic (faces, edge, and vertices) of specific geometric solids, with 100% accuracy.
Using an electronic geometric solid manipulative, the student will be able to identify the number of edges, faces, and vertices of six different geometric solids, with 100% accuracy.

12. FACE
The face is the flat side of any geometric solid. Some solids have many faces like Icosahedrons and others have none like sphere.
The face must be perfectly flat. It cannot have any curve to the surface.
Use the following link to identify the number of faces on the following solids. Be sure to list the number of sides on your workbook.
