Properties of Solid Shapes

1. Properties of Solid shapes
What are solid shapes?

2. Solid shapes
 Solid shapes are three dimensional. Three-dimensional shape can be
defined as a figure or an object or that has three dimensions length,
width and height. Unlike two dimensional shapes, three-dimensional
shapes have thickness or depth.

3. Solid shapes
 The attributes of a three-dimensional figure are surfaces/faces,
edges and vertices/vertex.
For example: This is a cube and it’s a solid shape. We will look at
some more solid shapes later in this lesson.

4. Types of solid shapes
Cuboid

5. The cube
Faces - 6
 Edges - 12
 Vertices – 8
Let's count the number of faces, edges and vertices on the cube.

6. Examples of cube shaped objects in real life.
Can you name three more?

7. The cuboid
Faces - 6
 Edges - 12
 Vertices – 8
Let’s count the number of faces,
edges and vertices on the cuboid.

8. Examples of cuboid shaped objects in real life.
Can you name three more?

9. More explanation
Look at the differences between
the cube and cuboid.

10. Let us observe a model of a
cube and cuboid
Models

11. Now we are going to create a model of a
cube and cuboid.
 You will need cardboards, glue, scissors, ruler, pencil and some explanations from me.

12. The properties of a cylinder
The cylinder has 2 flat faces, 1 curved
face and two edges. The cylinder has
no vertices.

13. Let’s try to identify objects in
our surroundings that looks
like a cylinder.
For example, a can of soup. Try
your best to find objects that
has the properties of a cylinder.
Can you name three objects
that looks like a cylinder?

14. Let us
observe the
properties of
a cylinder
using a
model
Take a look at the model

15. Let us observe a model of a
cylinder.
MODEL

16. We are going to
create a model of a
cylinder.
You will need cardboard, glue,a
circular object to draw two circles,
ruler and scissors.
Listen to the procedures.

17. The cone
The cone has one curved surface and
sometimes one flat surface.
The cone has one vertex and one
edge.

18. Let us observe a model of a
cone.
Take a look at the model

19. Examples of cones
in real life.
These are some examples of cones in real
life.
Can you name 2 more examples cones?

20. Let’s make a model of a cone
You will need, ruler, pencil, a circular
object, glue and cardboard.

21. The sphere
The sphere has no edges and
vertices.
The sphere has one curved face.
It looks like a ball.
I’m sure everyone knows what a ball
looks like.

22. The Sphere
Let us observe a model of a
sphere.

23. Examples of spheres in real life.
Can you name three more objects that looks like a sphere?

24. Let us now create a model of
sphere.
You will need glue, paper,
newspaper and tape. (insulation
tape).
