Sphere, sphereWhat’s your clue?

I’m like the soccer ball that you kick with your shoe. (tsk, with your shoe,

tsk)Cylinder, cylinderWhat’s your clue?

I look like a can of chicken noodle soup. (mmm, chicken noodle soup)

tooRectangular prismWhat’s your clue?

I’m like the box of tissue when you say achoo. (Ngee)

C. ReviewWhat are the shapes of the ff:

Triangle, square, rectangle

D. MotivationThe teacher will choose three students to join her to buy three items.

The vendor will come out from the store with the 2D item and a box full of 3D items.

The vendor will let the students to get the 2D items that they will buy. Then pick an item from the box of 3D items that has the same shape of the 2D item.

The teacher will let the students describe the 2D and 3D figures.

E. PresentationPlane figures have only two dimensions, the length and the width.Spatial figures have three dimensions, the length, width, height or thickness.

What are spatial figures again?Let us discuss the first spatial figure.

Generally, this is called a prism.Prism is a space figure which has parallel and congruent faces. And they are named according to the shape of their bases.What is the shape of its base?So, how is this prism called?It has bases, faces, edges and vertices.So, let us first discuss the bases.The top and the bottom of this figure are its bases.Each flat surface of solids is called a face.We call the sides of the faces as edges.And the point where the two edges meet is called vertex.

3 dimensional figures

RectangleRectangular prism

So, let’s have another prism.Where are the bases of this figure?

If this is the base of the prism, what is its shape?How do we call this prism?In this prism, where are the lateral faces?What is the shape of the lateral faces?So, it means that triangular prism have triangular base with rectangular faces.Point and count the edges of this figure.Where are the vertices?Could you please count?

Our next prism is this one.

Can you describe it?This kind of prism is special and it is called as cube.Where are the faces?What can you say about it?How many bases does this cube has?Point it.How many edges and vertices does it have?

Let us now proceed to this figure which is Cylinder.

What comes into your mind when you see this figure?Cylinder is made up of a curved surface. So, in this figure where is the curved surface?There are two congruent circular bases. Could you please point it?And the bases are flat surface.

Triangle

Triangular prism

Rectangle

Two

There are 12 edges and eight vertices.

can, tissue, etc.

Let us now proceed to this figure.

What comes into your mind when you see this figure?This figure is called a cone.It is made up of a curved surface and one circular base.Did you notice the difference of a cylinder and a cone? What is it?

The base is joined by a curved surface to a point called vertex.The base is a flat surface.

Pyramids have polygons as their base.

The faces are triangles with a common vertex. They are named according to their bases.How many bases does a pyramid have?How many faces does it have?How about the edges?How many vertices?

Our last figure is this one.

This is a sphere.Does it have a base?Does it have a flat surface?Does it have edges?Does it have a vertex?Correct. Give some objects that look like a sphere.

F. GeneralizationThe Spatial Figures are Rectangular prism, Triangular prism, Cube, Cylinder, Cone, Pyramid, and Sphere.

Ice cream cone, party hat, etc.

A cylinder has two congruent circular bases while the cone has only one circular base.

G. ApplicationDivide the class into two groups.

Give example of actual object for the following spatial figures.Group A Rectangular and triangular prism, cube, cylinderGroup B Cone, pyramid, sphere
