In math, Mrs. Yollis’ students have been working on geometric 3-dimensional shapes.
3-D shapes have flat faces, straight edges, and pointy vertices.

One 3-D shape is a cube. It has six square faces, twelve edges, and eight vertices.
* * * * *
Another 3-D figure is the cylinder. This space figure has two circular faces, zero edges, and zero vertices.
* * * * *
Rectangular prisms have six faces, twelve edges, and eight vertices.
* * * * *
A recognizable 3-D shape is the cone. It looks like an ice cream cone. The cone has one face, zero edges, and one vertex.
* * * * *
One very unusual 3-D shape Mrs. Yollis’ students have learned about is the square pyramid. The square pyramid has five faces (four triangular and one square base), eight edges, and five vertices.
* * * * *
The final 3-D shape our class learned about is the sphere. It has no faces, edges, or vertices.
Poor sphere.
Here is a PhotoPeach show we put together! See what the faces of the shapes look like!
3-D shapes are extremely fun to learn about!

Thanks to Mr. and Mrs. Kim for the photo of the pyramid at the Louvre Museum!
Do you know any 3-D figures we didn’t mention?
How many faces, edges, and vertices did you find?
