Lesson 4: Lesson plan Binary Numbers
Goal:
1. Students will gain an understanding of the binary number system.
Objectives:
1. Students will explore ancient number systems, use binary numbers to decode data,
and count in base 2
2. Students will be able to use binary numbers in computer applications.
Prerequisite:
None
Materials:
Handouts- printouts of PowerPoint slides

10. Number system
Description:
Students will be introduced to the binary number system and other non-decimal number
systems. They will learn to count, add and subtract in binary. They will learn how binary
numbers are used in computer applications.

Introduction:
We all know how to count, right? (Write 101 on board) What number is this? Is it always
one hundred one? Are you sure? What if I told you it was also five? We all use a number
system based on 10, called decimal. Other cultures in the past used number systems based
on other numbers. Computers use a number system based on 2, called binary.
Main Activity:
Lecture with PowerPoint slides and handouts
Written exercises and discussion
Closure/Conclusion:
Now that you know how computers count, next time we’ll find out how they use all those
ones and zeros.
Follow up lessons/Activities:
Lesson 5: The Multiplexer (MUX)
Assessment/evaluation:
Assessment quiz – students will convert a series of Base 10 numbers to binary, and
binary numbers to Base 10. Students will add pairs of binary numbers.
