Greeting Good morning class! How is Good afternoon, Ma’am. We
your day so far? are fine.
Before we begin the lesson this (Student will lead the prayer)
Prayer
morning, let us ask the
guidance of almighty God and Dear God,
let us enlighten our mind to
completely understand the May we, through your
lesson this morning. Would you blessings,
add purity to the world,
please lead the prayer? subtract evil from our lives,
multiply Your good news,
and divide Your gifts and
share them with others.
Amen.
(Students will arrange their
Classroom chairs and will pick up the
Management trash.)
I would like to request
everyone to arrange your
chairs properly and make sure
there are no trashes around
you.

understands the reasons for
coming to school regularly.
Class last meeting we
discussed about the
experimental probability, the It is a probability that has
example and its application in already been conducted
real life. ma’am.
Now, as a sort of review, what
is experimental probability?
Very good!
C. Motivation (Truth or
Dare Challenge)
Okay class, for you to enjoy
before the class start, I have
here your names in the box, I
will be chosen 5 students by

The class will start counting
and grouping.
I want you to divide the class
into 5 groups,now start
counting!
