Enjoy exploring the world of geometric solids! 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. 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.

Lesson Overview Instructions: Grade Level: Time: Lesson Goals: 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 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.

the World of Geometric Solids Let's Begin Exploring the World of Geometric Solids Start by printing off your workbook for the lesson “Workbook” Click the solids in order to begin 1 2 3 Edge Face Vertices

Face Home

FACE Home

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. Tetrahedron Cube Octahedron Dodecahedron Geometrical Faces Home

Let's find out what you know about faces! How many faces do you see in this picture? Click on the answer 9 8 6 4 Home

One More Time Hint: remember a face is always a flat side How many faces do you see in this octahedron? Click on the answer 9 8 6 4 Home

Nice Try! Remember: A face is any flat side 3 1 4 2 8 6 5 7 Remember: A face is any flat side This octahedron has 8 faces Home

Edge Home

Edge Home

Edge The edge is the place on a solid where two faces meet. The edge must always be a straight line. The red lines on the box to the right are all edges. Use the following link to identify the number of edges on the following solids. Be sure to list the number of sides on your workbook. Cuboid Cylinder Hexagonal prism Pyramid Geometrical Edges Home

Let's find out what you know about edges! How many edges does a cube have? Click on the answer 6 8 10 12 Home

Awesome! You knew that edge were the area where two faces came together! Check out this cool site. Electronic Geoboard Home

One More Time! Hint: an edge looks like a straight line How many edges does a cube have? Click on the answer 6 8 10 12 Home

Nice Try! Remember: an edge is where two faces meet As you can see this cube has 12 edges, marked with red lines. Home

Vertices Home

Vertices Home

Vertices The vertices are found were two or more edges come together. The edge must always be a straight line. The red lines on the box to the right are all edges. Click on the name of the solids to identify the number of vertices on the following solids. Be sure to list the number of sides on your workbook. Square Pyramid Cube Tetrahedron Home
