The document outlines a lesson plan on binary numbers for students, focusing on understanding its importance in computer technology and the mechanics of binary calculations. It explains how binary coding simplifies computer design by reducing costs and enhancing reliability compared to analog systems. The lesson includes interactive activities for students to practice converting binary to decimal numbers using bug cards.

2. After the lesson, the students will be able to:
 1. Perform calculations needed to complete task.
 2. Determine the number used in the binary
system.
 3. Appreciate the relevance of binary numbers to
computer technology.

4. What is binary
numbers?
Binary is a computer language system. With binary, it
became possible to have an exact state which would
have small errors. Way back in history, computers
made use of an analog to solve problems, but this
wasn’t accurate as binary code. With binary code,
the chances of committing errors are much, much
smaller.

5. What is binary
numbers?
Binary numbers simplify the design of computers and
related technologies. Computers need many transistors
to accomplish what they must accomplish, but through
binary numbers, it became easier and less expensive. It
needs less amount of necessary circuitry, which results
in the least amount of space, energy consumption, and
cost. It also provides reliability and safety.

6. What is binary
numbers?
Computers use binary because they can
only read and store an on or off charge.
Zero (0) is equivalent to off and one (1) is
equivalent to on. Any system that has an
“on” or “off” or “high” or “low” state can
be used to encode and/or manipulate data.

7. Count the
bugs!!!
Step 1
• Arrange the bug cards.
• Place them in a row.
• In number order,
highest first.
• This will be used to
decipher binary code.

8. Count the
bugs!!???.
.....!!!
Step 2
• Arrange the zero (0) and
one (1).
• Place them in a row.
• Choose any arrangement
you want.
• Align them with the bug
cards.

9. Count the
bugs!!???..
....!!!
Step 3
• Bugs assigned with zero (0)
is off.
• Bugs assigned with one (1)
is on.
• Count the bugs with 1 and
add them to get the binary
equivalent to decimal
numbers.

10. Let us try to solve
this.
Go to the board and try to find
out the value or equivalent of
binary number into decimal
number. The first to get to the
board and have the correct
answer will receive a prize.

 Each Clubhouse coders represent a binary
number.
 Convert the characters into binary number.
 Use the bug cards to decipher the code.
 Each group will be given a cardboard where
they write their answers.

16. Let us try to solve
this.
Divide yourselves between
male and female. In a
group of 10-12 persons per
group and be ready to
collaborate in solving this
problems..
