This document summarizes a daily lesson plan for a Grade 8 mathematics class on probability. The lesson plan covers key concepts of probability including calculating the probability of simple events and appreciating its importance in daily life. Example probability problems are provided to help students understand concepts like determining possible outcomes and calculating probabilities. A quiz is used to evaluate student learning, and additional activities are suggested for students requiring remediation.

Competency 53. (M8GE-IVh-1) Finds the probability of simple event.
D. Objectives (KSAs) At the end of the lesson, the students must be able to:
 Understand the idea of probability
 Calculate possible outcomes of probability of a simple event and make
predictions on it.
 Appreciate the importance of probability in daily living.

B. Other Learning Resources Standard Deck of Cards, Fair Dice, PowerPoint Presentation, Visual
Aids, Envelopes and Marking Pen
III.. PROCEDURES
A. Reviewing or presenting
the new lesson

2. B. Establishing a purpose for
the lesson
In the given pictures and situations above, one thing is common. Both
pictures and situations are talking about chances, specifically the
certainty and uncertainty that an event will occur. The mathematical
measures that talk about chances is known as Probability of an Event.
Using the IRF Chart Below, the teacher will also check the prior
knowledge of the students regarding the concepts of Probability of an
event.
(Initial – Diagnostic Assessment)
C. Presenting examples of
the new lesson
Questions:
1. How else can you find the number of possible outcomes?
2. Did you find difficulty in choosing which to wear? Why?
3. Aside from comfort, what do you consider when you choose an
outfit?

3. Probability is a measure or estimation of how likely it is that an event
will occur.

D. Discussing new concepts
and practicing new skills
#1
Probability Rules:
1. The probability of any event is a number (either a fraction, a decimal, or a
percent) from 0 to 1.
2. If an event will never happen, then its probability is 0.
3. If an event is sure to happen, then the probability is 1.
4. The sum of the probabilities of all the outcomes in the sample space is 1
E. Discussing new concepts
and practicing new skills
#2
1. A single die is rolled. What is the probability of rolling a number
that is a prime number?( the teacher will show a model of the die to
the students)
2. Jade has a box that contains 8 blue balls, 5 red balls, 3 yellow balls,
and 4 white balls. What is the probability that if she choose a marble
from the box without looking, or at random, she will get a white
marble?
3. Consider a well-shuffled standard deck of 52 cards. There are 4 suits
of cards: hearts (red), diamonds (red), spades (black), and clubs
(black). Each suit contains 13 cards: Ace, 2, 3, ….,9,10, king, queen,
and jack If a card is taken at random from the deck, find the probability
of drawing the following:
a. Getting an Ace
b. Getting a face card
( Revised – Formative Assessment)

4. F. Developing Mastery Math Quiz Bee:
1. This math quiz bee is composed of 10 items questions. The
questions were all about solving problems involving the probability of
an event.
2. Time Duration per question:30 seconds
3. Each group will be given a board. This is where you are going to
write your answers.
4. For uniformity in answers, answers must be expressed in a
simplified fraction.
5. On the first question, the group leader will be the one to write the
answer on the white board provided. On the next question, he/she will
pass the white board on the member on his/her left side. Same pattern
will follow on the succeeding questions.
6. Once the time is up, you are just allowed to raise your boards once I
told you to do so.
QUESTIONS:
1. A single die is rolled. What is the probability of rolling a number
that is greater than 4?
2. A bag contains 8 marbles numbered 1 to 8. What is the probability of
selecting an odd number?
3. Erick is asked to choose a day from a week. What is the probability
of choosing a day which starts with S?
4. In a 500-ticket draw for an educational prize, Jefferson’s name was
written on 50 tickets. What is the probability that he would win?
5. Each of the letters in the word CALCULATOR are on a separated
cards face down on the table. If you picked a card at random, what is
the probability that it is letter C?
6. Cherry has a box that contains 8 blue balls, 5 red balls, 3 yellow
balls, and 4 white balls. What is the probability that if she choose a
marble from the box without looking, or at random, she will get a non-
yellow marble?
7. A box contains 7 red balls, 5 orange balls, 4 yellow balls, 6 green
balls, and 3 blue balls. What is the probability of drawing out an orange
ball?
8. In a bowl, slips of paper were numbered from 1 to 12. What is the
probability of getting a prime number?

G. Finding practical
applications of concepts and
skills in daily living
welfare, and not for evil, to give you a future and a hope
Jeremiah 29:11(ESV)
The Teacher is trying to point out here that, even though there are a lot
of uncertainties in our lives (whether in our career, love life, etc.), one
thing is really certain and sure, the plans and directions of God in our
lives.
