The lesson plan teaches students about ratios by having them compare different groups of objects. Students learn that a ratio compares two quantities and can be written in fractional or colon form. They practice identifying ratios for different examples, such as the ratio of red stars to yellow stars or circles to squares. The teacher evaluates students by having them identify ratios in a picture and write other ratios in fractional and colon form for homework.

A. Preparatory Activity
1. Review
Good morning class!
Good morning ma’am!
We had already finished all the topics about
fraction, right?
Yes ma’am!
Can anyone of you tell what a fraction is?
Yes Alex?
Fraction is a part of whole
number.
Correct!
How many parts are there in a fraction?
There are two parts ma’am.
What are those parts of a fraction?
The two parts of a fraction are
the numerator and denominator.
Very Good!
Who can give an example of a fraction?
2/3
Another, Hannah?
6/8

2. 2. Motivation
Class, guess what are inside this box. If
you can guess it, you’ll be given one of it.
Who can try?
Candies
Who has another guess?
Chocolates
Ok, I’ll give you a clue. You can see these
during night time. Can you guess it now?
Stars
Very Good!
Do you want to have a star?
Yes ma’am!
Ok, if you want to have a star you must listen
to our lesson today because whoever answers
my questions later will be given a star.
B. Developmental Activity
1. Presentation
Who can count the no. of stars in the box?
Yes Arianne?
There are 25 stars.
Very Good!
How many are red?
Yes Marijoy?
There are 15 red stars.
Right!
How many are yellow?
Yes Joyce Ann?
There are 10 yellow stars.
Correct!
These stars have something to do with our
lesson today which is visualizing and expressing
ratio.
2. Discussion
The ratio of the no. of red stars to the yellow stars
is 15 to 10. I have here corns and bananas.
How many corns do we have?
There are 6 corns.
How about the bananas?
There are 2 bananas.
The ratio 6 to 2 compares the no. of corns to
the no. of bananas. Let’s have another example,

3. we have here circles and squares.
How many are circles?
There are 2 circles.
How many are squares?
There are 3 squares.
What is the ratio of the no. of circles to the
no. of the squares?
The ratio of the no. of circles to
the no. of the squares is 2 to 3.
Very Good!
Ratio can be written in two ways. Either fraction
form or colon form. Using the concept of fraction,
we can compare two quantities. Let’s say the no.
of chairs with the no. of tables inside this
classroom. How many chairs do we have?
There are 25 chairs ma’am.
Very Good!
How about the tables?
There are 4 tables ma’am.
Excellent!
Who can write the ratio of the number of chairs
to the number of tables in fractional form?
25/4
Very Good!
Now class, there is another way of rewriting this
ratio in fraction form and that is in colon form.
Example, in the ratio of the no. of chairs to the
number of table is 25:4.
In a ratio, there are two terms. We have the first
term and the second term. In the given example,
the first term is 25 and the second term is 4.
How about if I ask you to write the ratio of the
no. of vases to the no. of flowers, what should
be the 1st
term?
The 1st
term is 2.
What is the 2nd
term?
The 2nd
term is 6.
Very Good!
Let’s have another example. The no. of boys and
the no. of girls in the classroom. Who will write
the ratio of the no. of boys to the no. of girls?
10:15
Correct!
What is the 1st
term?
The 1st
term is 10.

4. What is the 2nd
term?
The 2nd
term is 15.
3. Generalization
Base on the given examples, can you now tell
what a ratio is?
Ratio is a comparison of two
quantities.
How do we write ratio?
We write ratio by using colon or
fraction form.
4. Application
I will divide you into three groups. Each groups
will be given an activity. Follow the directions that
is written on it. You have to choose your leader and
secretary. After 5mins, the leader will present
the output of the group.
(The teacher divides the pupils into three and gives
the activity to them)
(The pupils answer the questions)
5. Values Infusion
What should you do when you count an object in
order to get correct ratio?
We should be careful in counting
to get correct ratio.
IV. Evaluation
Directions: Using the picture, what is the ratio of;

5. 1. Number of goats to number of roosters
2. Number of chickens to number of all animals
3. Number of ducks to number of roosters and chickens
4. Number of chickens to number of ducks
5. Number of roosters to number of all animals
V. Assignment
Directions: Write each ratio in fraction form and in colon form.
1. 2 books for every 4 pupils
2. 9 players to 1 team
3. 12 flowers to 3 vases
4. 6 desks to 12 pupils
5. 2 chicks to 1 worm
