### 4A's Detailed Lesson Plan Grade 2

1. 1. Detailed Lesson Plan in Mathematics 2 I. OBJECTIVES At the end of the lesson the pupils should be able to: a. follow the steps in dividing 2 digit numbers by a 1 digit number; b. solve 2 digit numbers by a 1 digit number without remainder; c. appreciate the value of sharing in one’s own life; d. perform the operation of division.; II. SUBJECT MATTER A. Topic: Dividing Two Digit numbers by a One Digit number without remainder. B. Textbook: Math for Smart Kids pages 153-157 C. Materials: Instructional Materials, PowerPoint Presentation, Banana III METHODOLOGY Teacher’s Activity Pupil’s Activity A. Priming Activating Knowledge Learning Task 1-Review Last time we discussed about what? What are the 3 parts of division equation? What is a dividend? How about a divisor? Correct! What do we call to the answer in division? Very good! All your answers are correct. Now, class I have here an exercise about the parts of division equation. (The teacher will call one pupil to read the directions.) Directions: Identify if the encircled digit is a Dividend, Divisor, or Quotient. Write your answer on the space provided. _______ 1. ÷ 4 = 3 _______ 2. 28 ÷ 7 = _______ 3. 12 ÷ = 6 _______4. 24 ÷ 4 = _______5. 42 ÷ = 7 The Parts of Division Equation. The 3 Parts of Division Equation are Dividend, Divisor, Quotient. Dividend is a number that being divided. A divisor is a number that divides the dividend. The answer in division is called quotient. (The pupil will do as told) Dividend 1. ÷ 4 = 3 Quotient 2. 28 ÷ 4 = Divisor 3. 12 ÷ = 6 Quotient 4. 24 ÷ 4 = Divisor 5. 42 ÷ = 7 12 di git nu m be rs by a 1 di git nu m 12 di git nu m be rs by a 1 di git nu m 2 m be r wi th ou t re m 4 nu 4 nu m be r wi th ou t re m ai 6 m be r wit ho ut re 4 nu 6 m be r wi th 4 nu 2 m be r wi th ou t re m 4 nu 7 77 47 7n u m be r wi th ou t 6 m be r wit ho ut re 4 nu 6 m be r wi th 4 nu
2. 2. Very good! All your answers are correct! Do you have any question question in our previous lesson? Learning Task-2 Drill 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. Is that clear? Group 1 Group 2 Group___ got the highest score, so group ___ is the winner. B. LessonDevelopment Activity 1 Learning Task-3 Motivation What occasion is nearly coming? Why do we celebrate Christmas? Yes, it is. Group 1 Group 2 Christmas We celebrate Christmas because it is the birth of our Lord, Jesus Christ. 8 ÷ 2=8 ÷ 2= 25 ÷ 5=25 ÷ 5= 36 ÷ 6=36 ÷ 6= 8 ÷ 2=48 ÷ 2=4 25 ÷ 5=525 ÷ 5=5 36 ÷ 6=636 ÷ 6=6
3. 3. Correct! Learning Task-4 Presentation (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? 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. 2. Analysis Who are the characters in the story? What can you say about Santa Claus? For you class, is it important to share? Why? Now class Santa has a problem he wants to find out the total amount of candies did each child receive? Do you want to help him? (The teacher will present the word problem.) Sit properly. Be quiet. Listen carefully. The characters in the story are Santa Claus and the children. He is very generous. Yes, because when we share we can make people happy. Yes, teacher.
4. 4. 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? Based on the problem, what are given? What is the number to be divided? How about the number that will be divided to 51? What do you think is the operation to be used in the given problem? Why do you think we need to use division as our operation? Correct! How do we write the sign in division? (The teacher will call a pupil.) 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? Now class, we need to use this division sign in order for us to easily solve the problem. He wants to find out, how many candies did each child receive in all? 51 candies and 3 children 51 3 Division We need to use division because we need to divide the candies equally. (The pupil will draw the sign on the board.) ÷ 51 and 3
5. 5. So, we write the equation like this. What is the first step in the dividing 2 digit numbers by a 1 digit number? What digit is in the tens place? What is the divisor? Now let’s us divide 5 divided by 3 is equal to what ______? Very good! What is the next step? What is the quotient? So now class, we need to multiply 1 times 3 equals _____. What is the third step? We need to subtract 5 to 3. What will be the answer? Class, what is the step 4? What digit is in the ones place? Let us bring down the ones digit. Step 1 Divide the dividend by the divisor 5 3 1 STEP 2 Multiply the answer with the divisor 1 1 3 Step 3 Subtract 1 -3 2 STEP 4 Bring down the ones digit. 1
6. 6. What is the last step? Now let us do this again. What is the step 1? In this case we need to divide 21 divided by 3 is equal to what? Very good! Again, what is the second step? Let us multiply 7 by 3. Is how many? What is the third step? So, 21 minus 21 equals to what? Now Class, what is the quotient? What is 17 in the word problem? Very good! (The teacher will give another examples) Learning Task-5 Fixing Skills 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? STEP 5 Repeat the steps from 1,2,3 Step 1 Divide the dividend by the divisor 17 -3 21 STEP 2 Multiply the answer with the divisor 17 -3 21 21 STEP 3 Subtract 17 -3 21 -21 0 17 It is the total amount of candies each child received in all. Be cooperative. Be quiet. Listen carefully.
7. 7. 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. 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 Rudolph bakes 3 pies a day. How many days will it take him to bake 36 pies? Activity Card Group 2 The 5 elves are roasting 65 ears of corn. How many ears of corn will each elf get? 3. Abstraction What are the steps in dividing 2 digit numbers by a 1 digit number without remainder? Very well said! Yes, it is. 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
8. 8. 4. 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. I am going to rate you according to your speed and accuracy. Is that clear class? Directions: Find the quotient: __ 1. 3/36 __ 2 2 /26 Yes, it is. IV. Evaluation Directions: Find the quotient: 1. 2 /24 ____ 2. 3 /63 ___ 3. 2 /42 ___ 4. 4 /48 ___ 5. 5 /65 V. Assignment Directions: Find the quotient: __ 1. 9/ 99 __ 2. 3 /60 __ 3. 5 /55 __ 4. 6/66 __ 5. 2/46
