Shape
NZC LEVEL 2
GMS2-1 Sort objects by their spatial features with justification GMS2-2 Identify and describe the plane shapes found in objects. |
NZC LEVEL 3
GMS3-1 Classify plane shapes and prisms by their spatial features. GMS3-2 Represent object with drawings and models. |
NZC LEVEL 4
GMS4-1 Identify classes of two and three dimensional shapes by their geometric properties. GMS4-2 Relate three dimensional models to two dimensional representations and vice versa. |
NZC LEVEL 5
GMS5-1 Deduce the abgle properties of intersecting and parallel lines and the angle properties of polygons and apply these properties. GMS5-2 Create accurate nets for simple polyhedra and connect three-dimensional solids with different two-dimensional representations. |

6) Types of Lines
7) Parts of a Circle
8) What are Prisms?
In geometry, a prism is a polyhedron with an n-sided polygonal base, another congruent parallel base (with the same rotational orientation), and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases. All cross-sections parallel to the base faces are congruent to the bases. Prisms are named for their base, so a prism with a pentagonal base is called a pentagonal prism. The prisms are a subclass of the prismatoids.

9) Faces, Edges and Vertices of 3D Shapes
10) Cross Sections in Prisms
The cross section in a prism is the shape you get when cutting straight across an object.
11) What are Pyramids?
12) Isometric Drawings
Isometric projection is a method for visually representing three-dimensional objects in two dimensions in technical and engineering drawings. It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angles between any two of them are 120 degrees.
