Faces
Faces: a face is a side of a shape. NOT:

Edges
Edges: a line where two FACES meet in a shape.

Vertices
A point when 3 or more edges meet in a shape.
A vertex can be also called as corners.

How many faces do you see on the sphere?
![Page 9: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/9.jpg)
Sphere
![Page 10: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/10.jpg)
Sphere
If you guessed 0 your right! Lets see if you can guess how many
edges there are?
![Page 11: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/11.jpg)
Sphere
Well you guys are just so smart! That’s right the sphere also has 0 edges!
![Page 12: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/12.jpg)
Now lets see if you guys can guess how many vertices the sphere has!
The sphere also has 0 vetices!
![Page 13: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/13.jpg)
Sphere
Now what do you notice about the sphere after learning about it’s faces, vertices and edges there are?

Triangular prism
![Page 15: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/15.jpg)
Triangular prism
A triangular prism has 5 faces. A triangular prism has 9 edges
![Page 16: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/16.jpg)
Triangular Prism
A triangular prism has 6 vertices A triangular prism can be as easy to
find in your home. For example you’re moms wallet or your wallet.

Rectangular prism
![Page 18: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/18.jpg)
Rectangular prism
A rectangular prism has 6 faces. Also the rectangular prism has 12
edges. A rectangular prism also has 8 vetices.

Cone
![Page 20: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/20.jpg)
Cone
A cone has 0 edges. Can you find out how many faces it has
from the picture?
![Page 21: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/21.jpg)
Cone
It turns out that the cone only has 1 face. Do you know where that one face is on the cone?
![Page 22: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/22.jpg)
Cone
Yes the one face is on the bottom of the cone!
Can you guys guess how many vertices the cone has?
![Page 23: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/23.jpg)
Cone
Winner winner chicken dinner! Yes the cone has 1 vertex or vertices.
How many edges does the cone have?
![Page 24: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/24.jpg)
Cone
Well if you said zero yes! Because the cone only has 1 face so its not possible for it to have any edges!
![Page 25: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/25.jpg)
Rectangular pyramid
![Page 26: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/26.jpg)
Rectangular pyramid
The rectangular pyramid has 5 faces. It also has 8 edges.
![Page 27: Geometric solids](https://reader033.vdocument.in/reader033/viewer/2022061220/54bc32a84a795918128b458d/html5/thumbnails/27.jpg)
Rectangular pryamid
The rectangular pryamid also has 5 vertices.
A rectangular pyramid can be found in your home or possibly you can make a rectangular pyramid!

Review
Now that we’ve gone threw the slide show its review time.
Which shape has 0 faces 0 vertices and 0 edges?
Which shape look like a square?
