Checking of Attendance May I request the secretary for the attendance? Who are the absent? Secretary: Okay Ma’am. The absent… Okay, Thankyou ! D. Checking of Assignment Last time we discussed about what? The Parts of Division Equation. What are the 3 parts of division equation? The 3 Parts of Division Equation are Dividend, Divisor, Quotient. What is a dividend? How about a divisor? Correct! Dividend is a number that being divided. A divisor is a number that divides the dividend. What do we call to the answer in division? Very good! All your answers are correct. The answer in division is called quotient. Now, Let us check our assignment about the parts of division equation. Directions: Identify if the encircled digit is a Dividend , Divisor , or Quotient. Write your answer on the space provided. _______ 1. 12 ÷ 4 = 3 _______ 2. 28 ÷ 7 = 4 _______ 3. 12 ÷ 2 = 6 _______4. 24 ÷ 4 = 6 _______5. 42 ÷ 6 = 7 (The pupil will do as told) Dividend 1.12 ÷ 4 = 3 Quotient 2. 28 ÷ 4 =4 Divisor 3. 12 ÷2 = 6 Quotient 4. 24 ÷ 4 = 6 Divisor 5. 42 ÷6 = 7 Very good! All your answers are correct! Do you have any question in our previous lesson? None. E. Motivation Let’s have a game! I need 3 representatives from each group. I have here a basic division equation on the board. All you have to do is to give the correct answer. Form a line, the first pupil in the line will answer first, followed by the second and up to the last member.. The group who will get the highest score will be the winner. I’m going to rate you according to your speed and accuracy.

Group 1 Group 2 Group 1 Group 2 36 ÷ 6 = 25 ÷ 5 = 8÷2= 36 ÷ 6 = 25 ÷ 5 = 8÷2= 36 ÷ 6 = 6 25 ÷ 5 = 5 8÷2=4 36 ÷ 6 = 6 25 ÷ 5 = 5 8÷2=4 Group___ got the highest score, so group ___ is the winner. II. LESSON PROPER A. Activity What occasion is nearly coming? Why do we celebrate Christmas? Correct ! Christmas ! We celebrate Christmas because it is the birth of our Lord, Jesus Christ. (The teacher will tell a story about Santa Claus) Now class I’m going to tell a story. But before that what are the standards to be followed in listening to a story? Sit properly. Be quiet. Listen carefully. Very good! I expect you to behave well. Santa Claus lives in a nice city called Santa Claus Ville. Every day he works hard, in wrapping gifts for children. Santa Claus is very generous. He loves to share. He looks for good children all over the land. He always sure to have with him a bundle of toys. For the good little girls and little boys. One day when Santa Claus is walking along the street he saw 3 children, but he has only 51 candies left in his bag. So, Santa Claus divides the candies equally to the children. Santa Claus was very happy to see the smile on the face of the children. B. Analysis Who are the characters in the story? The characters in the story are Santa Claus and the children. What can you say about Santa Claus? He is very generous. For you class, is it important to share? Why? Yes, because when we share we can make people happy. Now class Santa has a problem he wants to find out the total amount of candies did each child receive.

Vinzons Ave., Daet, Camarines Norte A locally responsible and globally competitive learning institution capable of producing highly competent, morally upright, and productive citizenry. Tel, Number 154-721-3254 COLLEGE OF TEACHER EDUCATION Do you want to help him? Yes, teacher. (The teacher will present the word problem.) Santa Claus has 51 candies. He divides it equally to the 3 children. Santa Claus wants to find out , how many candies did each child receive in all? What is the problem of Santa Claus? He wants to find out, how many candies did each child receive in all? Based on the problem, what are given? 51 candies and 3 children What is the number to be divided? 51 How about the number that will be divided to 51? 3 What do you think is the operation to be used in the given problem? Division Why do you think we need to use division as our operation? We need to use division because we need to divide the candies equally. Correct! How do we write the sign in division? (The teacher will call a pupil.) (The pupil will draw the sign on the board.) ÷ Very good! To easily solve the problem we need to follow these Steps in Dividing 2 digit numbers by a 1 digit number. The Steps in Dividing 2 Digit Numbers by a 1 Digit Number without remainder are: STEP 1 Divide the dividend by the divisor STEP 2 Multiply the answer with the divisor STEP 3 Subtract STEP 4 Bring down the ones digit STEP 5 Repeat the steps from 1,2,3 Again class, what are given? 51 and 3 Now class, we need to use this division sign in order for us to easily solve the problem. So, we write the equation like this. 3√51 OLLCF: College of Teachers Education Midterms 2023 Page 4 of 8 MISSION OUR LADY OF LOURDES FOUNDATION VISION OLLCF is committed to provide dynamic, excellent, and client-oriented services to ensure relevant and quality higher education accessible to all. Vinzons Ave., Daet, Camarines Norte A locally responsible and globally competitive learning institution capable of producing highly competent, morally upright, and productive citizenry. Tel, Number 154-721-3254 COLLEGE OF TEACHER EDUCATION What is the first step in the dividing 2 digit numbers by a 1 digit number? Step 1 Divide the dividend by the divisor What digit is in the tens place? 5 What is the divisor? 3 Now let’s us divide 5 divided by 3 is equal to what ______? 1 3√51 Very good! What is the next step? STEP 2 Multiply the answer with the divisor What is the quotient? 1 So now class, we need to multiply 1 times 3 equals _____. 1 3√51 3 What is the third step? Step 3 Subtract We need to subtract 5 to 3. 1 3√51 -3 What will be the answer? 1 3√51 -3 2 Class, what is the step 4? STEP 4 Bring down the ones digit. What digit is in the ones place? 1 Let us bring down the ones digit. 1 3√51 -3 21 What is the last step? STEP 5 Repeat the steps from 1,2,3 Now let us do this again. What is the step 1? Step 1 Divide the dividend by the divisor In this case we need to divide 21 divided by 3 is equal to what? 1 3√51 -3 21 OLLCF: College of Teachers Education Midterms 2023 17 3√51 -3 21 Page 5 of 8 MISSION OUR LADY OF LOURDES FOUNDATION VISION OLLCF is committed to provide dynamic, excellent, and client-oriented services to ensure relevant and quality higher education accessible to all. Vinzons Ave., Daet, Camarines Norte A locally responsible and globally competitive learning institution capable of producing highly competent, morally upright, and productive citizenry. Tel, Number 154-721-3254 COLLEGE OF TEACHER EDUCATION Very good! Again, what is the second step? STEP 2 Multiply the answer with the divisor Let us multiply 7 by 3. Is how many? 17 3√51 -3 21 21 What is the third step? STEP 3 Subtract So, 21 minus 21 equals to what? Now Class, what is the quotient? 17 3√51 -3 21 21 0 17 What is 17 in the word problem? Very good! It is the total amount of candies each child received in all. (The teacher will give another examples) Class I’m going to group you into two groups. But before that, what are the standards to be followed in having a group activity? Very good! I have here an envelope. Each envelope has an activity card and the materials that you will use in your group activity. All you have to do is to analyze the given problem and find its quotient. The leader of the group will present their work. Be cooperative. Be quiet. Listen carefully. I will give you 5 minutes to finish your work. I will rate you according to your speed and accuracy. Is that clear? Activity Card Group 1 OLLCF: College of Teachers Education Midterms 2023 Yes, it is.

Abstraction What are the steps in dividing 2 digit numbers by a 1 digit number without remainder? The Steps in Dividing 2 Digit Numbers by a 1 Digit Number without remainder are: STEP 1 Divide the dividend by the divisor STEP 2 Multiply the answer with the divisor STEP 3 Subtract STEP 4 Bring down the ones digit STEP 5 Repeat the steps from 1,2,3 Very well said! D. Application Now, let’s have a game! It is boys vs. Girls. The game is called “EAT ME FIRST”. I need 2 representatives from the boys and girls. You’re going to eat first the banana in order for you to answer the given division equation on the board. The first pupil in the line will answer first follow by the last member. The group who will finish first and got the correct answers will be the winner. Directions: Find the quotient: 1.) 3√ 36 2.) 2√ 26 I am going to rate you according to your speed and accuracy. Is that clear class? Yes, it is.
