Data Representation Lesson Plan

The daily lesson plan aims to teach students how computers represent data in binary form. It involves explaining how decimal numbers can be converted to binary through repeated division by 2 and recording the remainders from bottom to top. Students will practice this conversion by hands-on activities of changing decimal numbers like 128, 50, 20, and 40 to binary. Finally, they will complete an assessment matching exercise and conversion homework to solidify their understanding of data representation in computers.

Daily Lesson Plan School: BUNGA INTEGRATED Grade Level: 7/8

SCHOOL

Teacher: CHRICYL MAE E. LEGANAD Learning Area: ICT

I. OBJECTIVES

At the end of the lesson students must have:

 Analyzed the data representation in a computer.


 Performed conversion of decimal number to binary units.

II. CONTENT

A. TOPIC DATA REPRESENTATION IN COMPUTER

B. References Technology and Livelihood Education: LAS in


Computer Hardware Servicing Exploratory Course
Grade 7/8

C. Instructional Materials Laptop and projector

IV. PROCEDURE

B. Motivation Show picture that represent how computer and


human recognize number. Let the student’s
compare the difference between how computer and
human recognize number based on the given
example.

C. Presentation Explain Data Representation and Binary System


DATA REPRESENTATION
IN A COMPUTER
Data or characters like, numbers, letters, symbols,
sound, video or pictures need to convert first into
a machine-readable form like binary form.
The On state is represented by “1” and OFF state
is “0”. These 1 and 0 forms the electrical signal
that only computer can accept and understand
USING BINARY SYSTEM IN COMPUTER
BIT- A binary digit that hold only one of two
values: 0 or 1
- the smallest data on computer
-bit are assembled into a group of eight to form a
BYTE

D. Activity Proper/Discussion Seat Work : Let the student convert the decimal
number 128 into binary by following the given
rules

RULES IN CONVERTING DECIMAL TO


BINARY
1. Divide the number by 2
2. Copy the quotient and write the remainder
3. Divide the quotient by 2
4. Repeat steps 2 and 3 until you get a
quotient of 0.
5. Read the values of the remainder from the
bottom to top. Write the values to get the
binary value of the decimal number.

quotient remainder
128

Answer:

quotient remainder
128/2 64 0
64/2 32 0
32/2 16 0
16/2 8 0
8/2 4 0
4/2 2 0
2/2 1 0
1 /2 0 1

128= 10000000

Another example

quotient remainder
50/2 25 0
25/2 12 1
12/2 6 0
6/2 3 0
3/2 1 1
1 /2 0 1

50= 110010
E. Analysis

 What is the binary value of 128?


 10000000
 What mathematical operation used in
converting decimal to binary?
 Division
 In what direction you are going to read
the remainder to get the binary value?
 Bottom to Top

F. Application Let the students answer another seat work.


Convert the decimal number 20 and 40.
Answer:
20
20/2 10 0
10/2 5 0
5/2 2 1
2/2 1 0
1 /2 0 1

 What is the binary value of 20?


 20 = 10100
40

40/2 20 0

20/2 10 0

10/2 5 0

5/2 2 1

2/2 1 0

1/ 2 0 1

 What is the binary number of 40?


 40 = 101000
G. Abstraction  What are the two numbers that computer
could only recognize?
 0 and 1
 What is the difference between bit and
byte?
 Bit- two values; byte – eight
values
 What are the two state represented by 0
and 1?
 On and off state
