III. Instructional Procedure

TEACHER’S ACTIVITY PUPIL’S ACTIVITY

A. Preparatory Activities

1. GreetingsEverybody stand and let us pray. (The pupils will stand and pray)Lea kindly lead the prayer. Good morning Ms. ChavezGood morning class! Good Morning visitors

Good Morning classmatesGood morning!

You may now take your seat.

2. Checking of AttendanceClass, who are absent today? Ma’am nobody is absent today.Very Good!

3. SongBefore we start our lesson let us sing a song first.

(Pupils will sing a song)

4. DrillClass, I will flash numbers which you are going to solve and give its quotient.

Answer:

2, 5

4, 3

4, 6

6, 3

5. Review

Let us have a review. What was our lesson yesterday?

Our lesson yesterday was about dividing a whole into parts.

Very good!So let’s see. I have here a presentation of different shapes.Read the direction first.

Direction: Cut the objects into its indicated equal parts.

1. Cut the heart into 2 equal parts.

2. Cut the triangle into 3 equal parts.

3. Cut the orange into 4 equal parts.

I. DEVELOPMENTAL ACTIVITIES

1. Motivation

Who among you love to eat cakes? (Pupil’s will raise their hands) When do you usually eat cakes? During special occasions.

Will you name some occasions wherein you see and taste delicious cakes? Birthdays

Weddings Christening

In eating a cake, do you eat it as a whole? No Ma’am.How do you eat cake? We sliced it into parts and then put it on a plate.

Very good!

10÷5

28÷7

20÷5

24÷4

30÷6

12÷4

18÷3

9÷3=

Do you share your food to your families of friends?

Yes Ma’am.

2. Presentation

I have objects on the table.What are these? Cake, pizza pie, water melon, knife/plastic knife,

plates handkerchief

Nice!Using the knife, I will cut the water melon

into 4 pieces, but before that I want to remind all of you that this tool is dangerous. That’s why we must be careful in using it.

Look at the watermelon. How many equal parts does it have? The watermelon has 4 equal parts.

Very Good!

3. Discussion

If I will give one part to Jasmine.How many are left?Very Good!

Since Jasmine got one part of the watermelon it will show in fraction as

1 4

Therefore all the four parts have the fraction form 1

4

Thus: 4 is called the denominator, or the total number of equal parts and 1 is the numerator as the shaded part.

Let us have the other objects.Who wants to slice the cake into 6 equal parts? (Pupils will raised their hands)

Are these parts of the cake having the same size? Yes Ma’am.

How many equal parts do Renan sliced the cake? Renan sliced the cake into 6 equal parts.

Very good! If I will separate the 1 part of the cake? How many equal parts are left? 5 equal parts

Very good! How many parts are taken? 1 part

How do we write it in fraction form? 16

Very good! Which part is the numerator? 1

Which part is the denominator? 6

Will you draw 1 on the board using the shape of 6 the cake?

1 6

Let us have other example.Look at this pizza pie, into how many parts does

this pizza divided? Ma’am, the pizza pie is divided into 2 equal parts.

What do you call each part? Ma’am, each part is ½ because the pizza is divided into 2 equal parts.

Will you draw it on the board, Bea?

Very good!

4. Fixing Skills

Class, I will group you into four groups, this is the group 1, group 2, group 3 and the group 4. Each group will have 5 members.

You will form your line here in front. The first member of each group will be the first one to answer the right fraction of the picture that I am going to show, and then you will write it on the board, followed by the next member of the group up the last member.

5. Generalization

How do we identify fractional parts of a given whole? We identify fractional parts of a given whole by

counting the total equal parts as the denominator and the shaded part or each part as the numerator.

That’s right! What do you call if 1 whole is divided into 3 parts? Ma’am when a whole is divided into 3 equal parts.

Each part is called 1 . 3

Very good! How about if a whole is divided into 8 equal parts? Ma’am when a whole is divided into 4 equal parts,

each part is called 1. 8

Remember class, to identify fractional parts of a given whole by counting the total equal parts as the denominator and the shaded part or each part as a numerator.

6. Application

Shade the parts of the following figures according to the given fractional part.(Kulayan ang mga bahaging hugis batay sa fractional parts nito.)
