Preliminary Activities
Good morning, class! Good morning, teacher!
How are you today? We’re good teacher
Okay! It’s good to hear that you are doing great!
Let us bow our head for the prayer. (The students pray)

Activity
If I have ten sets of yellow mangoes, five sets of green
ones, and five sets of bananas, How many sets of fruits
do I have?
Can anyone solve this problem?
Ok very good
But how he can get that answer?
Discussion
Do you have any idea about our topic for today's class?
About addition, teacher.
Yes, you have an idea; it is about addition. But it is not
simply adding numbers; our topic today is all about
illustrating addition as “putting together, combining, or
joining sets.”
And what is it all about?
The process of combining or putting things together is
called addition. The numbers that we add or put together
are called addends. The answer in addition is called the
sum. The symbol for addition is the plus sign (+).
What do we call the process of combining or
putting things together? Addition, teacher.
The answer of addition is called what? Sum, teacher.
Okay very good!
So what we did earlier was combine or join the sets of
fruits, and that is an example of addition.
Since there are ten sets of yellow mangoes, five sets of
green mangoes, and five sets of bananas, We combine it
all, so we have 20 sets of fruits.
Did you get it class? Yes, teacher.
Okay very good
And now we were going solve this another set of
problem.
And now we were going to solve another set of
problems.
Mario bought 5 junk foods, 3 candies, and 4 lollipops. If
we were going to add it all, how many would it be
altogether?
The first thing to do in class is to determine the given
number. Then we will combine it so we can have an
answer.
So in the problem, we have 5 junk foods, 3 candies, and
4 lollipops.
And we combine them, so we have this process...
5 junk foods + 3 candies + 4 lollipops = 11
We combine all the numbers, so we have 11, so there are
11 foods that Mario has bought. Yes, teacher!
Add or combine the number,
teacher.
Did you get it class?
How are we going to get the answer? Addition, teacher.
What operation will we use?
We can get it teacher by
Input combining or joining the sets.
Again, class, how can we get the answer or the total of
the addition?
Very good
And now I have here a set of activities you are going to
do to solve the different problems.
In the garden, there are different kinds of trees. There are
10 coconuts, 7 jackfruits, and 5 mabolos. How many
trees are there in the garden?
Deepening
Okay, I want somebody from the class to answer my
questions. Student 1: You have 21 fruits in
all, teacher.
Question 1: If I bought 10 apples, 5 oranges, and 6
pineapples, how many fruits do I have? Adding the given numbers is my
solution, teacher, and I add or
combine the numbers. I combined
How did you get 21? What solution have you used? the numbers to get the answer,
which is 21.
Okay, very good solution!
Activity
The class is divided into 2 groups, and each group is
given sets of materials to be used in the activity. Each
group was going to count the sets of popsicle sticks, and
they were going to make or construct a different example
situation of addition using the popsicle sticks.

Directions: Construct three (3) example situation that
involve addition using the popsicle sticks given.
Synthesis Yes, teacher. Yesterday I went to a
Okay what have you learned today in our store and I bought 8 chewing
discussion? gums. I bought 4 sweet chewing
Alright, Joy can you give an example wherein gums and 4 sour chewing gums.
you can relate our topic? Involving adding So all in all I have 8 chewing
numbers? gums.
