3D Geometry

Here is what we will be learning for 3D Geometry:
-compare and sort prisms and pyramids by geometric properties (i.e., number and shape of faces, number of edges, number of vertices), using concrete materials;
-construct rectangular prisms (e.g., using given paper nets; using Polydrons), and describe geometric properties (i.e., number and shape of faces, number of edges, number of vertices) of the prisms.
-identify and describe the two-dimensional shapes that can be found in a three dimensional figure
 – describe and name prisms and pyramids by the shape of their base (e.g., rectangular prism, square-based pyramid);

This figure is a rectangular prism.

It has:

8 vertices

4 rectangular faces

2 square faces

12 edges

Here is a net for a Rectangular Prism:

Square based Pyramid

-Has a square base and all other faces are triangles that meet at a common vertex.
-5 vertices
- 4 triangular faces
- 8 edges
