A. Activating
Prior Knowledge Short Review
The teacher will ask questions on the previous lesson.
What are the conversion units for computer storage?
How many of kilobytes in a 16 gigabytes of flash drive?
How did you get the answer? Used a range of teaching strategies that enhance
learner achievement in literacy and numeracy skills.
Possible Answer: (PPST 4.5.2)
16 Gigabytes x 1000 = 16,0000 Megabytes
16 x 16,000 = 16,000,000 Kilobytes Note to the teacher:
The teacher will emphasize the unit conversion for
computer storage.
B. Establishing 1. Lesson Purpose:
Lesson Purpose Show a video clip about how computer operates.
https://www.youtube.com/watch?v=M41M9ATm49M
Ask questions to generate ideas from the students.
There will be a hot potato game in asking questions.
*How do computers interpret and store data?
*What is the smallest unit of data?
*Why does computer use binary instead decimal numbers?
*What are values of binary number system?
*What is the role of 0s and 1s in the computer operation?

to its number value.
Column A Column B
1. Binary a. 0-7
2. Octal b. 0 and 1
3. Decimal c. 0-9 and A-F
4. Hexadecimal d. 0-9
Binary Number System
The binary number system uses only two digits: 0 and 1. The numbers in
this system have a base of 2. Digits 0 and 1 are called bits and 8 bits
together make a byte.
Octal Number System
The octal number system uses eight digits: 0,1,2,3,4,5,6 and 7 with the
base of 8.
Decimal Number System
The decimal number system uses ten digits: 0,1,2,3,4,5,6,7,8 and 9 with
the base number as 10.
Hexadecimal Number System
The hexadecimal number system uses sixteen digits/alphabets:
0,1,2,3,4,5,6,7,8,9 and A, B, C, D, E, F with the base number as 16.
Here, A-F of the hexadecimal system means the numbers 10-15 of the
decimal number system respectively.
Group Activity: The teacher will group the students into three and they
C. Developing will identify the steps in conversion of decimal to binary numbers. Each

Method 2 Exponential: Binary system is based of two counting system.
Multiply 1 times 2 and the answer will be multiplied again by 2. Keep
multiplying 2 until the result will be 128.

Group 3
Method 3 Yes or No Question: You can begin your conversion of the
number 192 to a binary number by asking a question and performing the
following calculation.
1 2 4 8 16 32 64 128
0 0 0 0 0 0 1 1
Step 1: Is 192 greater than or equal to 128? → Yes → Put a 1 in the 128
column and subtract 128 from 192 → 192 – 128 = 64
Step 2: Is 64 greater than or equal to 64 → Yes → Put 1 in column 64
and subtract 64-64 = 0
Step 3: Is 0 greater than or equal to 32 → No → Put 0 on column 32
Step 4: Is 0 greater than or equal to 16 → No → Put 0 on column 16
Step 5: Is 0 greater than or equal to 8 → No → Put 0 on column 8
Step 6: Is 0 greater than or equal to 4 → No → Put 0 on column 4
Step 7: Is 0 greater than or equal to 2 → No → Put 0 on column 2
Step 8: Is 0 greater than or equal to 1 → No → Put 0 on column 1
Combining these eight binary digits forms a binary number of 00000011,
as shown below.
