### 3 DIMENSIONAL PLANE SHAPES LESSON PLAN AND NOTE FOR PRIMARY AND SECONDARY SCHOOL

DEFINITION
3 Dimensional shapes are shapes which have 3 dimensions i.e length, breadth, height.
Examples are cuboid, cube, sphere, cylinder, pyramid, cone and prism.

Properties of The Cuboid
1. It is a solid which has rectangles for all its faces.
2. It has 6 rectangular shaped faces.
3. It has 12 edges or lines
4. It has 8 corners or vertices.

Properties of The Cube
1. All it faces are square shapes
2. The cube has 6 squared face.
3. It has 12 straight edges equal in length.
4. It has 8 corners.

Properties of The Cylinder
A cylinder is a shape with 2 circular ends and a long curved side.
1. It has 3 faces, 2 circular and 1 curved.
2. It has no vertices or corners
3. It is made of one rectangle and 2 circles.

Properties of The Sphere
A sphere is a perfectly round shapes like ball, earth, tennis ball and basketball.
1. The sphere has one circular face.
2. It has no corner or vertex.

Properties of The Cone
The cone is a solid which usually has a circular base and slanting sides and pointed at the other end or at the top called its vertices.
1. It has two faces, one curved and the other circular.
2. It has a curved edge.
3. It has on corner or vertex.

PROPERTIES OF THE PYRAMID
A pyramid is a solid with a triangular or square or rectangular base and sloping sides meeting at one vertex called the apex.
1. a. Square base pyramid has 5 faces; the 4-side faces are triangular while the base face is a square.
b. It has 5 vertices.
c. It has 8 straight edges.

2. a. A triangular based pyramid has 4 triangular shapes
b. It has 4 vertices
c. It has 6 straight edges

3. a. A rectangular based pyramid has 5 faces
b. It has 5 vertices
c. It has 8 straight edges.
4. a. A hexagonal based pyramid has 7 faces.
b. It has 7 vertices
c. It has 12 straight edges.

Properties of Prism
A prism can be defined as a solid object with matching ends and several sides which are the same width all the way up. (That is, a solid shape with the same shape across its length).
1. A prism has 2 opposite parallel faces
2. The 2 opposite parallel faces are always the same shape.

The Nets of 3-Dimensional shapes
The net of any solid is the plane shape, which when cutout and folded can be made into the solid shape.

STARTER
-Begin the lesson by;
Showing them videos on 3-D shapes.
Then showing them a shape of some 3 – D objects and picture collage to see and pass round one after the other.
-Begin the lesson by showing them a Milo tin and ball so they can identify a cylinder and a sphere.

- Begin the lesson by showing them a video on pyramid and prism.

- Begin the lesson by showing them how to make a dice which is cube-like in shape from a thick cardboard.
Monday - Thursday
- Define 3-dimensional shapes.
Properties of cuboid, cube.
