Learning Experience : Teacher’s Activity A. Preparation : 1. Warm Up Oh ohohohoo..(YEH!)
Pupil’s Activity
Mathematics is the time for logical listening This has place value, probably a fraction. We’re searching for the knowledge and thrill. Oh Oh.. add, subtract, multiply, divide, we carry mathematics in our daily life. We love calculation and manipulation. In improving our education (oh oh)
We should care in learning math It leads us to our own Right path(2x) We should care –a-a-a-are! Do you dare! (2X) We should care in learning math. Good Evening Grade 4! Do you want to learn that action song? How are you today? Any interesting things happened to all of you yet?
Good Evening Ma’am ! Yes Mam. We’re fine Ma’am !
Before we go down to business, we would like to introduce ourselves. I’m Teacher Gina, I’m Teacher Chara and I’m Teacher Shine and we will be your Math Teacher tonight?

Setting Rules
Ok now before we proceed I have here Mr. Potato. Do you know Mr. Potato from the Movie the toy story? Mr. Potato here have something to say about our today’s classroom Rules. Our senses will be our rules, the eyes, the ears, and the mouth. “Kindly say again my 3 rules”
Eyes, the ears, and the mouth.

And the last one, the most important one is the mouth. When I say mouth class, this is the quite mouth. I want you all to shut your mouth as I am discussing in front. Is that clear?
Ear/ listening ears

The eyes, the ears and the mouth.
4. Review Before we move on to our new lesson today let’s have a review on adding numbers. What do you call the number that being added together. Addends What about the total of the two numbers. Very Good class, now I need 4 students. Let’s play a game entitled NAME THE PARENTS GAMES. I have here the answer or the babies of the numbers we need. All you need to do is write the addends to board I will give to you. The first participant who can give answer without duplication will have the point. First to get 3 points will lead. Ok. Example 15 1. 19 2. 23 3. 85 4. 27 5. 31 6. 75 7. 21 8. 13 9. 35
Sum
Yes Ma’am !
10. 95
5. Motivation Now let’s play a game. I need 3 pupils. This game is spinning a wheel all you need to do is answer the given decimal problems accurately and with speed. There is an amazing prizes waiting for you.
8 + 7, 6 + 9, 10 + 5, 11 + 4.
0.31 + 0.60 = 0.59 + 0.2= 0.389 + 0.31 = 5.17 + 8.23 6.14 + 4.76 7.32 + 5.21
B. Lesson Proper: 1. Presentation : Very Good, Now class base from what we have answered and based from your observation what do you think is our topic for today? . Now let’s have our group activity. Now class I have a here a classroom grocery math. Group 1 and group 2 answer the following. All you need to do is to fill out the respective prices of the items needed. Add the given decimals with or without regrouping.
Addition of Decimals without or with regrouping
21.59 + 12.34 = 33.93 13.36 + 34.39 = 47.75 11.79 + 25.88 = 37.37 34.39 + 25.88 = 12.34 + 11.79 =
25.17 + 8.23 33.45 6.14 + 4.76 10.9 7.32 + 5.21 12.53
25.17 + 5.21 30.80 24.50 + 73.23 97. 73 2.
Discussion :
Very Good class, now how did you come up in your solutions?
First we arrange the numbers in column, Then we align the decimal point, Add like whole number, and put the decimal point directly below the decimal point in the addends.
Correct answer. You have to see to it that all the numbers are arrange and as well as decimal point. Do you understand class? 3.
4.
Application
Generalization.
In adding decimals, how do we write the addends? How are the decimal points placed?
5.
Evaluation
In adding decimals: 1.Arrange the numbers in column, 2.Align the decimal point, 3.Add like whole number, and 4. Put the decimal point directly below the decimal point in the addends.
Now class I have a here a classroom grocery math. You can pick 2 items you wanted but you have to add the prices of those items accurately and with speed. And when you answer it you will get the items. Write the answer on the board.
Now class who among you are members of 4PS. Do you know how your parents get Money when payout?
Very good class in the ATM or the Automated Teller Machine. Now I have here an ATM and you will withdraw the problems in our atm. Ok? Do it on the board.
C. Assignment: Copy your assignment in your notebook.
Prices 7.09 8.61 9.27 5.63 6.16 7.89 17.09 12.30 13.38 26.95
In the ATM
4.45+9.27 4.36+5.63 7.09+2.30 8.61+1.11 5.14 + 5.76
Find the sum. 1. 3.76 + 4.356 2. 23.34 + 0.3 3. 0.76 + 0.23 4. 37.786+ 2.632 5. 762 + 1.38 Read and solve. A butcher weighed two hogs. One hog weighed 35.45 kg, while the other weighed 41.75 kg. What is the total weight of the two hogs?
