III. Learning Activities Teacher’s Activity Preparatory Activity Good afternoon class. Before we start, let us greet our visitors for today.

Pupil’s Activity

Pupil’s singing the chant.

Ok, now I prepared a song entitled “Chuga Dance”. I will sing it first and show you the steps then after that we will do it all together. Did you enjoy our sing and dance number? Alright. I am happy to see that everybody Enjoyed our sing and dance number. 1. Drill Mastery Written: Class, there is a hidden message on the board. What you are going to do is to find the factors of the given number in each box. We

Yes ma’am.

48 O = 6X6 T = 8X7 L = 8X8

I = 6X8 M = 9X9 H = 9X6

V = 7X7 A = 6X7 E = 9X8

2. Review Ok class, let us check your assignment yesterday. Read first the problem then We will going to answer. Is that clear class?

Yes ma’am.

Joan sells ripe bananas in Marikina Public Market. She has 3 kaings of bananas to sell. Each kaing has 50 bananas. One morning she sold 80 of the bananas. How many more bananas were left for her to sell? What is asked in the problem?

Numbers of bananas were left her to sell.

What are the given facts?

3 kaings of bananas with 50 pieces each and 80 bananas that was sold

What is the hidden question?

How many bananas are there in 3 kaings?

What are the processes to be used?

Multiplication and Subtraction.

What is the mathematical sentence?

80 - ( 3 x 50 ) = n

What is the final answer?

70 bananas were left

Ok class, very good! Who got all correct answers?

Pupil’s raising their hands.

Ok, give yourselves a magnificent clap.

( sounds play) 3. Lesson Proper 2. Motivation Hey kids! Would you like to help Dora find the steps in solving a story problem?

Yes!

I think the bag pack will help us! ( sing the song) Bag Pack (4x) What is the first step? Let us Find out and see. (sing the song)

Ask.

Let us find out what is the Second step. (sing the song)

Given.

What is the third step? (sing the song) Let us find out the fourth one. (sing the song) What do you think is the fifth step? (sing the song) Our last and sixth step? (sing the song)

Dora says, “Thank you, thank you For helping me find the steps”.

Hidden question.

Processes. Mathematical sentence Solve and Label

You’re welcome Dora.

3. Presentation of New Lesson Class, we have here a story problem to analyze. I want you to read it silently. Mang Emilio can gather 4 baskets of atis and 5 baskets of mangoes in a day. How many baskets of fruits can he gather in two days? Let us analyze our story problem. Do you still remember the steps inside Dora’s bag pack? What are those?

Yes ma’am. - know what is asked - know what are given - find the hidden question - think of the

processes to use - write the mathematical sentence - solve and label Very good! 4. Discovery and Exploration Let us go back to our story Problem. Now, I have here a chart. What does it tell us to do? ASKED

SOLVE AND LABEL

Number of baskets of fruits can Mang Emilio gather in 2 days.

What are the given facts?

After knowing the given facts, can you find the hidden question from our problem? What is the hidden question?

Ok, what do you think are the processes to be used in solving our story problem?

4 bags of atis 5 bags of mangoes 2 days

Yes ma’am. We are going to find out the number of fruits in one day.

The processes to be used are addition and multiplication

Very good! After knowing the processes to use, we are going to write the mathematical sentence. What is the mathematical sentence? Ok good! Now, we are going to solve and label.

I am very happy that you really participated. I hope that everybody have learned from our first problem.

(4+5) x 2 = n (4+5) x 2 = n 9x2=n 9 x 2 = 18 18 baskets of fruits

Now, we are going to sing a song so that everyone of you will still have energy. (Teacher gives the tune) I’m alive, alert, awake, enthusiastic! (4x)

Pupil’s singing

Sit up straight. What can you see on the board?

Story problem.

Good! We have another story problem to analyze and solve. Read it silently and you are going to do what we did earlier. Is that clear class?

Yes ma’am.

5. Working on other Exercises Mario bought 3 coloring books for Ph 85 each and 8 boxes of crayons for Ph 48 each. How much did Mario spend in all?

I am so glad that you really understood our lesson.

IV. Generalization How do we analyze and solve two-step word problems involving multiplication? What are the steps? 1. 2. 3. 4. 5. 6.

Know what is asked Know what are given Find the hidden question Think of the processes to use Write the mathematical sentence Solve and Label

Application – Group Work Activity Now, I will divide the class into four groups. you are going to answer the story problems cooperatively. In other words, you have to work as a group ok?! Select a leader for your group. But before that, let us sing Dora’s song. (Teacher gives the tune) Come on charity! Everybody Let’s go! Come and let’s get do it, I know that you can do it! What are we doing? (Problem solving) 3x Come and let’s get do it, I know that you can do it! Ok very good!

Here are the problems for each group. Group 1:

Yesterday, 27 Grade Three – Charity pupils went to the library. each pupil read 3 books. Today, 16 Grade Three – Amity pupils are at the library. Each pupil read 5 books. How many books were read by the section Charity and section Amity?

Group 2:

Mother asked her daughter Marie to buy 24 eggs at Ph 5 each. She gave her daughter Ph 200. Marie went to the store immediately. She gave the seller Ph 200, how much change would she gets?

Group 3:

Princess bought 2 sandwiches for her snacks. Each sandwich costs Ph 6. If she gave the seller Ph 20, how much will be her change?

Group 4:

Everyday, Carl Anthony drinks 2 glasses of milk while Antonnette drinks 3 glasses of milk a day. How many glasses of milk did they drink in 5 days?

I will be giving you 5 minutes to answer. Start working. Now, discuss your work with the whole Class. How’s your working with your group? Did you help one another?

Yes ma’am. When helping each other it makes the work easier.

That’s right! When everybody is cooperating and helpful, the work becomes easier. Now, did you arrive at the correct answer?

Yes ma’am.

Very good! Class, what is the trait does the Charity and Amity have?

-They love to read. -They are good readers.

What is the importance of reading books?

We will learn more when we read books.

Whatelse?

We can get different information from reading books. We enjoy when we read stories from books.

How about the story problem of group 2? What have we learned from it?

How about the story problem from group 3? Why did Princess buy sandwiches rather than junk foods?

Very good! How about the story from Group 4? What do we get from drinking milk?

Eating nutritious foods. Because she knows that eating junk foods are not healthy to eat.

Our bones will become stronger.

We will become healthy. I am very happy to hear those from you. I am so glad that all of you have learned from the different story problems that we have solved.

VI. Evaluation Now, I will give you a story problem to work on. Direction: Read the problem carefully. Choose the letter of the correct answer. There are 6 boxes of apples with 24 apples in each box.

What do we need to find out first? A. Number of red apples in all B. Number of green apples in all C. Number of apples in all D. Number of boxes of apples in all 4. What are the processes to be used? A. Addition and Subtraction B. Subtraction and Division C. Addition and Multiplication D. Multiplication and Subtraction

5. What is the mathematical sentence? A. ( 5 x 24 ) – 80 = n B. ( 5 + 24 ) x 80 = n C. ( 5 x 24 ) + 80 = n D. ( 5 x 24 ) x 80 = n 6. What is the final answer? Write the solution and label your answer correctly.

VII. Homework Direction: Read the problems carefully. Use the steps in analyzing and solving the story problems.

3. Vanessa bought 2 bundles of flowers at Ph 65 a bundle. She gave the seller Ph 200. How much was her change? 4. Francis planted 5 rows of carrot plants with 20 plants in each row and 3 rows of carrot plants with 15 plants in each row. A rabbit ate 25 of the plants during the night. How many carrots did Francis find in the morning?
