# Lesson Plan: Computer as an IPO System
### Grade Level: Primary 4
### Subject: Computer Education
### Time: 50 minutes
---
## Objective:
By the end of the lesson, students should be able to:
1. Understand what a computer is and its basic parts.
2. Explain the IPO (Input, Process, Output) concept.
3. Identify examples of input devices, processing units, and output devices.
## Materials Needed:
1. Projector/Smartboard
2. Computer (for demonstration)
3. Images of different computer parts (keyboard, mouse, CPU, monitor, printer, etc.)
4. Worksheets
5. Markers and board
## Lesson Structure:
### Introduction (10 minutes)
1. **Greeting and Attendance:** Greet the students and take attendance.
2. **Warm-up Activity:**
- Ask the students if they have used a computer before and what they use it for.
- Briefly discuss their responses to set the context.
3. **Introduce the Topic:**
- Write "Computer as an IPO System" on the board.
- Explain that IPO stands for Input, Process, and Output.
### Direct Instruction (15 minutes)
1. **What is a Computer?**
- Define a computer as an electronic device that can be programmed to carry out instructions.
- Show the main parts of a computer: keyboard, mouse, CPU, and monitor.
2. **Explain IPO System:**
- **Input:** Devices like keyboards, mice, scanners that send data to the computer.
- **Process:** The CPU or computer's brain, where data is processed.
- **Output:** Devices like monitors, printers that display or produce the result.
3. **Visual Demonstration:**
- Use images or a real computer to point out each part.
- Demonstrate a simple input-process-output cycle using any application, such as typing (input), processing it inside the CPU, and displaying text on the monitor (output).
### Guided Practice (10 minutes)
1. **Worksheet Activity:**
- Hand out a worksheet with images of different computer parts.
- Ask students to label each part and identify whether it is an Input, Process, or Output device.
2. **Group Activity:**
- Divide the students into small groups.
- Give each group a scenario (e.g., typing a letter, playing a game).
- Have them describe the IPO process involved in their scenario.
### Independent Practice (10 minutes)
1. **Individual Task:**
- Ask students to draw their own computer and label the input, processing, and output parts.
- Encourage creativity and neatness.
### Conclusion (5 minutes)
1. **Review:**
- Summarize the key points of the lesson.
- Ask students to recall what IPO stands for and give examples of each part.
2. **Q&A:**
- Allow students to ask any questions they might have.
- Encourage them to share one new thing they learned today.
### Assessment:
- Observe student participation during activities and discussions.
- Review the worksheets and individual drawings to assess their understanding.
### Extension Activity:
- For early finishers or extra practice, allow students to explore a simple application (such as a drawing tool on the computer) and identify its IPO process.

### Homework:
- Ask students to look at electronic devices at home and think about how they follow the IPO system. They can write down or draw one example to share in the next class.
This lesson plan provides a structured approach to teaching Primary 4 students about the concept of a computer as an IPO system, combining direct instruction with interactive activities to ensure engagement and comprehension.
