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.

Enjoy exploring the world of geometric solids!

This lesson was created using The Gallery Front Door method of lesson navigation. This method was selected for its ease of use for the grade level addressed in this lesson.

Instructions: Read all of the information carefully. Click the shapes at the bottom of each slide to advance to the next slide. At the main page of the lesson (slide 9) you will be presented with a gallery of images that you can click on to move through the lesson. Select a concept and begin your exploration. Click on the Home link at any time to take you back to the main page. Be sure to answer the questions carefully in order to continue.

Grade Level:Third Grade

Time: You will have 30 minutes to complete this lesson.

Lesson Goals: Identify the characteristics of each solids.

∆ The names of the solids∆ The number of faces∆ The number of edges∆ The number of vertices

Goal– 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.

• 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.
