• Illustrated story or video demonstrating shutting down a computer
• Flashcards with key terms

Building Background/Connection to Prior Knowledge:

• Review previous lessons on computer components and basic functions.
• Relate shutting down a computer to actions students are familiar with, like turning off lights or closing a book.

Embedded Core Skills:

• Critical thinking: Analyzing different shutdown options and their purposes.
• Communication: Discussing and explaining the process of shutting down a computer.

Learning Materials:

• Textbook: “Introduction to Computer Basics for Primary Students”
• Worksheets on computer functions and shutdown options
• Interactive computer simulation or game demonstrating shutdown procedures

Reference Books: Lagos State Scheme of Work for Primary 2 Computer Studies

Instructional Materials:

1. Start the lesson by revising the previous topic, which was “Understanding Computer Mouse Functions.” Review the uses of a mouse and how it helps to navigate the computer screen.
2. Introduce the new topic: “Understanding Computer Shutdown Options.” Explain that shutting down a computer is like putting it to sleep after finishing our work.
3. Show pictures or diagrams of computer screens displaying sleep, hibernate, restart, and shutdown options. Describe each option briefly, using simple language and examples.
4. Allow students to give their own contributions by asking questions like:
   • “When do you think it’s best to shut down a computer?”
   • “Have you ever seen these options on a computer screen?”
5. Correct students’ understanding as needed. Emphasize the importance of shutting down a computer properly to save energy and keep it working well.
