review your past lesson yesterday. What have
you studied yesterday?
How many days are there in a week?
So, can you tell me what are the days of the
week?
(Write the days of the week in order and let
the pupils read them twice.)
Pupil’s Activity
 We have studied about the days of the
week.
 There are 7 days in a week.
 The days of the week are Monday,
Tuesday, Wednesday, Thursday, Friday,
Saturday, and Sunday.

B. Developmental Activities
1. Presentation
I will read you a story about a Grade 1
pupil named Allan. Listen as I read the story.
After the end of classes on March, Allan
was excited because next month, he will go to
Manila to spend his vacation at his cousin’s
place. When the month of April came, he
went to Manila. There, he visits his cousin
John. John take him to the park and they also
played at the playgrounds there. They also
shop at the mall. He did not notice that it is
already the end of April and he has to go
home.
He went back home on May. He was so
excited and he can’t wait to tell his friends
what he experienced during his vacation in
Manila.
(after reading, ask the pupils)
Who was the Grade one pupil in the
story?
When did their classes ended?
What did he do after their classes ended?
When did he went to Manila?
When did he went back home?
2. Posing a Problem
In the story, Allan was excited after
classes because he will go for a vacation
next month after the end of classes. So
what month would Allan go for a
vacation?
3. Discussion
In the story, Allan’s classes ended on
March then he went to Manila on April
then stayed there for one month so he
went home on May. (write the month on
the board)
(the class will listen attentively as the
teacher reads the story)

How many months do we have in all?
How many months are there in a year?
Let us count.
(count together)
There are twelve months in all.
Therefore, there are twelve months in a
year.
Let us arrange the months of the year in
the right order. (Let the pupils arrange
the months in a pocket chart while asking
them specific celebrations to guide them
to arrange the months in the right order.
Ask questions which relate to their
individual experiences.)
(Show a calendar)
This is a calendar, this is where we see
the dates and months in a year. What do
we call this again? What did you observe?
How do we use a calendar?
(Read the months in the pocket chart in a
right order after arranging them.)
(Let the children observe the calendar)
(Pupils’ answers)
4. Group Activity
(Divide the class into 3 groups.)
Now class, I will group you into 3. We will
have a group activity. But first, what
should we do if we will have a group
activity? What are the standards in doing
group activity?
(let the children suggest standards. Then
post a chart with written standards then let
the children read it.)
