Introduction:
Yesterday (last week, etc.) we learned how modern electronic computers work. Today we’re
going to look at how the central processor unit in a computer works.
Main Activity:
Lecture with PowerPoint slides and handouts
Discussion questions
1. What are the five basic CPU elements?
Closure/Conclusion:
Today we learned the physical processes a computer uses to function. But in order to be useful,
computers must be able to communicate. Next time, we’ll learn about binary numbers, which are
used to build computer languages.
Follow up lessons/Activities:
Lesson 4: Binary Numbers
Assessment/evaluation:
Take assessment quiz.
Sample quiz questions
1. What does the memory unit do?
2. The basic CPU is composed of ____ different elements.
