B. LESSON PROPER
Teacher’s Activities
ACTIVITY Activity 1:
Let the students play the game “The BOAT is Sinking” with a short story. Every
(Cooperative Learning,
Games)
situations has a specific task. Please listen carefully.
“Once upon a day, JBOI went to the downtown to buy a shirt.
Task 1: If you were JBOI what color of shirt will you choose? Group yourselves
(Assessment for
learning) according to the color of the shirt you will choose. Shout out the color and find
your groupmate.
Task 2: After JBOI bought his favourite colored shirt he decided to meet his 4
friends. Group yourselves into 5.
Then the friends playfully did more fun acts.
Task 3: Size of your waistline
Task 4: Shoe size
ANALYSIS
Guide Questions:
1. How did you find the activity in task 1,2,3, and 4?
2. What difficulties did your group encounter during the activity in task
1,2,3, and 4?
3. What are the categories used in task 1,2,3, and 4?
4. What category is discrete? What category is continuous? Do you know?
ABSTRACTION Today we will learn about categories or variables.
A random variable is a characteristic under study that assumes different values
for different elements.
A random variable that can be measured numerically is called a quantitative
variable.
A random variable whose values can be counted is called a discrete random
variable.
Examples:
1. Number of students present
2. Number of red balls in a jar
3. Number of heads in flipping 3 coins
A random variable that can assume any numerical value over a certain interval
or intervals is called a continuous random variable.
Examples:
1. Height of students in a class
2. Weight of students in a class
3. Time it takes to get to school
Recall the tasks you played earlier. Can you identify which is a DRV? CRV?
Further Questions to be asked:
1. What did you notice with the example? Which are discrete random
variables? Continuous random variables?
2. Give examples of discrete random variables and continuous random
variables.
3. Differentiate discrete random variable/s from continuous random
variable/s.
APPLICATION Using the PLICKERS app, identify the following random variables whether it is
discrete or continuous.
Cooperative Learning
1. Daily allowance in school
2. Number of text messages sent in a day
3. Number of siblings
4. Weight in kilograms
5. Total family income
6. Number of cellphones owned
7. number of friends in Facebook
EVALUATION Test 1. Illustrate a situation where you can use random variables (discrete and
continuous).
Test 2. Identify if each of the following variable is discrete or continuous.
1. distance travelled in going to school
2. number of family members who are working
3. amount of time spent using the internet
4. number of buildings in school
5. number of patients in a hospital
