14/08/2017
Subject: Mathematics Period: 3rd and 4th Time:
80 minutes
Topic: Polygons (Chapter 5, Geometry)
Teaching Skill/s in Focus: Giving Instructions to Organize
Learning Activities
Previous Knowledge of the students: students have an idea of different
shapes like triangle, square, circle and rectangle.
Teaching/Learning Materials: Different shapes of polygons,
example: rectangle, rhombus, trapezoid, square, pentagon, hexagon, laptops and projector.
Teaching strategies: Demo cum
Lecture
Life Skill Values: Critical thinking
Lesson objectives: By the end of the lesson, each
child will be able to:
- tell
what a polygon is after the teacher’s explanations.
- name
seven polygons and talk about their characteristics correctly after the
activity.
- fill
in the table about its edges and vertices of each polygons appropriately
after the learning activity.
Lesson Revision (3 minutes)
Gaining attention
Teacher: Ready to rock!
Students: Ready to roll!
Teacher: Good morning children! How are you
all?
Student: Good morning Madam! We are all fine
and thank you.
Revise on the previous lesson by
asking some questions. (I will pose the question, wait for sometimes and then point
out the child’s name so that everyone in the class will be engaged in thinking
of the answer). Example
- What
are the shapes that we have learnt in the previous class?
- Can
you name any shapes that you find in our classroom?
- What shape does your classroom door represents?
(As the students name the shapes, I
will make a list on the computer and show it on the PowerPoint).
Lesson Introduction ( 5 minutes)
Teacher: Ok children today we are going to
learn about “Polygons.”
(Show the topic on the power point)
Do you have any ideas about
polygons? Discuss in your group for 1 minute. (Rally Robin)
Let one from each group share “what
is a polygon?”
Then I will say, ok children! You
all tried your best. Now let us see what are polygons?
Gaining attention: Class!Class!…..yes!yes!
After that I will show the following
polygons on the Power Point.
I
will explain to the whole class about the above definition. I will also teach
them like rectangles, squares, triangles, trapezoids, rhombus etc are all
polygons. All 2D shapes are polygon except for the circle because circle is not
made of straight lines.
So
these are the three main characteristics of the polygon.
Again I am going to explain about
its faces, vertices and edges one by one by on the PowerPoint.
I will also let children come up
with more examples as different shapes have different numbers of faces, edges
and vertices.
Teach some of the non-examples of
the polygons. Show a chalk box
A
chalk box
Is this a polygon? (Expected
answer is no)
Explain like:
The box is not a polygon because it
is not a flat shape.
It is a solid shape. It is a 3D
shape.
Cylinder
Cylinder is also not a polygon
because firstly it is not made of straight lines.
You can see curve line on the top
and at the bottom. Again it is a solid and 3D shape.
Note: All these above shapes I will show
it on the power point and do the explanation verbally.
Activity Direction (2 minutes)
- Now
we are going to do an activity.
- I
will show the table on the power point.
- You
are going to copy the table in your notebook.
- Count
and fill in the table about its edges and vertices.
- I
have done one example for you all.
- For
this activity you will get 20 minutes.
- You
are going to do it individually.
- After
that you will exchange your book with your shoulder partner and check.
Checking
the understanding of the Instruction (1minutes)
- What
are we going to do? (Pose the question, wait for a few seconds and call
a child’s name).
- How
many minutes do you get to do an activity?
- Are
you going to do it in a group or individually?
Activity 1: Individual Activity. (20 minutes)

Monitoring: I will move around the groups and
help needy students in carrying out their work smoothly.
Follow up activity (3 minutes)
I will tell children to exchange
their note book with their shoulder partner and cross check their answer
with the answers given on the power point.
Activity 2: Group Activity. (27 minutes)
·
I
am going to divide you in groups of 3.
·
Each
group will get one laptop.
·
You
will do turn wise.
·
First
to desktop
·
Open
Microsoft office word.
·
Draw
any five polygons and color it.
Monitor: Here I will move from group to group
and help children to follow each and every instruction step by step. I will
also check each and every group whether they are following it correctly or not.
Extended Activity (7 minutes)
Instructions:
·
Now
choose any one of the polygons
·
Show
its face, vertex and edge with an arrow.
Monitor: I will move around and help needy
ones.
Lesson Closure (2 minutes)
Ok! Before we close our lesson let
us reflect on what we have learnt in this period. I will call any of the
students and let them tell what they have understood from today’s lesson. After
that I will summarize the lesson by saying:
- A
polygon is a flat shape, made of straight lines and lines are closed.
- There
are three characteristics of polygons :
a. It is flat
b. It is made of straight lines.
c. Lines are joined or closed.
Homework [Textbook]
- Do question number 8 and 9 on page 105.
Thank you students and see you
tomorrow.
THANK
YOU
