I.
Objectives
a. Define a perfect square.
b. Understand and identify perfect squares.
c. Develop learners’ number sense
II.
Subject Matter
Topic: Introduction on Perfect Squares
Materials: PPT presentation, print-out puzzles
Strategies: Interactive learning
III.
Procedure
Teacher’s Activity
1. Preliminary Activities
Learners’ Activity
-
A. Daily Routine
- Prayer
- Greetings
- Checking of Attendance
B. Review
-
Quiz about the last topic
C. Motivation
-
What are the properties of a square?
-
A square is a quadrilateral whose
interior angles and side lengths are all
equal.
-
Is this a square?
-
How many units?
-
Now, try making a square with 2 tiles
-
Is it a square? What figure is that?
-
Now let’s try adding 2 more tiles and
let’s see if it is possible to form a square
-
Rectangle with 4 equal sides
Each interior angles of a square is
90°
-
Yes
-
Only 1 unit
-
It’s a Rectangle
-
Here’s your task
I’ll give you 4 minutes to build as many
different squares as you can on your
grid papers.
After 4 minutes check the learners’
papers
2. Lesson Proper
A. Introduction
-
The activity we’ve done has something
to do with our lesson for today and now
I want you to read these questions and
hopefully after this discussion you can
answer them correctly.
-
Can you make a square from 5
tiles? Why or why not? Draw a picture
or create a model to support your
answer.
-
Why do you think that 1, 4, 9 and 16 are
called perfect squares?
-
How can we determine if a number is a
perfect square or not?
B. Discussion
-
A perfect square by definition is a
number that is the square of an integer
-
What is an integer again?
-
Good Job!
-
In other words, we could take an integer
then square it and the resulting number
is a perfect square.
-
-
𝒎 = 𝒏𝟐
You may not realize it, but you have
already been exploring perfect squares.
-
An integer is a number that can be
written without a fractional
component.
-
The perfect squares can be found along
the diagonal of the multiplication table
when a whole number is multiplied by
-
N
-
i
t
s
e
l
f
𝑚=
9
-
There are infinite numbers of perfect
squares but let’s take a look to a few to
get an idea what they look like.
-
Let n be an integer; m be the perfect
square
-
𝒎 = 𝒏𝟐
Example #1
-
n=1
𝟐
-
𝒎=𝟏 ?
-
Therefore, 1 is a perfect square
-
𝒎=𝟏
-
𝒎 = 𝟗 and it’s a perfect square
Example #2
-
n =3
-
𝒎 = 𝟑𝟐 ?
-
Very Good!
Example #3
-
n=4
-
Excellent!
-
Can someone draw the tiles now?
-
Amazing!
3. Application
Matchy Matchy
Direction: Match the puzzle pieces as fast as
you can
-
𝒎 = 𝟒𝟐
-
𝒎 = 16
4. Generalization
-
No, because it’s not a perfect
square.
-
1, 4, 9, and 16 are called perfect
squares because they’re the
square of an integer
-
By drawing tiles
-
By using this equation 𝒎 = 𝒏𝟐
Let’s wrap it up!
IV.
-
Since you did a great job, I believe you
can answer these questions easily
-
Can you make a square from 5
tiles? Why or why not? Draw a picture
or create a model to support your
answer.
-
Correct!
-
Why do you think that 1, 4, 9 and 16 are
called perfect squares?
-
Correct!
-
How can we determine if a number is a
perfect square or not?
-
Excellent!
