B. Priming Activities
Motivation:
Miss Universe 2018 Catriona Gray: World's Living Silver Lining
Miss Catriona Gray has a bag full of candies and she wanted to give it to the children of
Tondo, Manila. There are 4 pcs. of Flat Tops, 8 pcs. of Hany, 6 pcs. of Lollipop, 4 pcs. of Milkita and 2 pcs. of
Chooey Choco.
Guide Questions:
1. List all the possible outcomes/sample space.
2. How many candies are there in all?
3. Which candy has the greatest chance to be selected by the child?
4. How about the least chance to be selected?
C. 4A’s Development of the Lesson
1. Activity
Approach: Constructivist
a. Task 1
Multiple Intelligences Survey for Grade 8 Students
Students will be asked to divide themselves into smaller groups. Each member of the class
has a freedom to choose their desired activity according to what they feel like performing at the
moment.
Multiple Intelligences
1. Arts and Crafts
2. Drama/Speech
3. Music
4. Dance
Number of Students
5. Sports
TOTAL
Questioning:
1. How many students like
a. Arts and Crafts?
b. Drama/Speech?
c. Music?
d. Dance?
e. Sports?
2. Among the multiple intelligences given, which is the most liked by the students? How
about the least liked?
3. If a student will be picked randomly, what is the probability that he/she likes:
a. Arts and Crafts?
b. Drama/Speech?
c. Music?
d. Dance?
e. Sports?
b. Task 2.
A meaningful Discussion
The teacher leads a discussion about Probability of an Event.
2. Analysis
1. What have you noticed in our activity?
2. Would you able to identify which among the multiple intelligences was most liked by
the students? How about the least liked?
3. When do we say that an event will probably happened or has a greater chance to be
selected?
4. What is Probability of an Event?
5. How can we find the Probability of an Event?
3. Abstraction
In a sample space of equally liked outcomes, the probability of an event, denoted as P (E), is
computed on the basis of favourable outcomes and the number of possible outcomes. Event is any
subset of a sample space.
Example 1
There is a bag full of candies. There are 4 pcs. of Flat Tops, 8 pcs. of Hany, 6 pcs. of Lollipop,
4 pcs. of Milkita and 2 pcs. of Chooey Choco. What is the probability that a child will select:
a. Flat Tops?
b. Hany?
c. Lollipop?
d. Milkita?
e. Chooey Choco?
Solution:
a. There are 4 pcs. of Flat Tops in the bag.
b. There are 8 pcs. of Hany in the bag.
c. There are 6 pcs. of lollipop in the bag.
d. There are 4 pcs. of milkita in the bag.
e. There are 2 pcs. of Choey Choco in the bag.
Example 2
A fair die will be rolled. What is the probability of getting:
a. a number “4” ?
b. an odd number?
c. a number less than 3?
Solution:
a.
b.
c.
Values Integration:
What statement can you make about yourself that is possible and impossible?
*I believe . . . and I thank you!
4. Application
Approach: Collaborative
“Who’s the Smartest? Who’s the Luckiest?”
Mechanics:
The class will be divided into five groups. There will be 10 problems to answer. Each
problem has a time limit of ten seconds. Each group should write their answer on a manila paper and
should raise it when time is up. The group with the correct answer will pick a card that corresponds to
their points. The group with the highest correct answer will be declared as “Smartest” while the group
with the highest total points earned will be declared the “Luckiest”.
Problems:
1. A fair die is rolled. What is the probability of getting:
a. a number “3”?
b. a number that is even?
c. a number less than 5?
d. a number greater than 6?
e. a number that is prime?
2. Fifteen identical cards are labelled 1 to 15. Find the probability of that
a card drawn at random may be:
a. a number with the digit 1
b. a number that is divisible by 5
c. a number greater than 2 but less than 10
d. a number that is perfect square
e. double digits
D. Evaluation
Direction: Read the problem comprehensively. Encircle the letter of the correct answer.
A circle is divided into 10 equal parts to form a spinner. It is numbered and colored as
shown below. Find the probability that when the spinner is spun, the pointer will stop at:
1. A yellow sector
a. 2/5
b. 3/5
2. A number divisible by 2
a. 1/2
b. 1/5
3. Red sector with odd number
a. 2/5
b. 1/5
4. White sector with even number
a. 1
b. 0
5. A number greater than 4
a. 3/5
b. 1/5
c. 1/5
c. 1/10
c. 1/10
c. 1/10
c. 2/5
E. Agreement
