3.	Replicate composite 2-D shapes and 3-D objects.

Specific Outcomes

Sort 2-D shapes and 3‑D objects, using two attributes, and explain the sorting rule.

Describe, compare and construct 3-D shapes, including:

Specific Outcomes
6.	Describe 3-D objects according to the shape of the faces and the number of edges and vertices.

Three-dimensional objects can have two dimensional representations. Shading can be used to distinguish 3-D objects in 2-D representation, such as shading in a circle into a sphere. Dotted lines show hidden edges.
Three-dimensional objects can be identified and described based on properties such as the number and shape of faces and edges and the number of vertices.
The faces of a 3-D object are related to 2-D shapes.
Three-dimensional shapes can be seen from different perspectives. When a 3-D object is moved in space, not all the same faces, vertices or edges may be visible; however, the 3-D object retains all these same properties no matter what its orientation in space.
Similar 3-D objects exist in a variety of sizes, but retain the properties of their class of 3-D objects.
Examples of 3-D objects can be found in the environment.
