Lesson Plan

• Describe the core components of a desktop computer and their primary functions.
• Explain at least three key characteristics that differentiate desktop computers from other system types.
• Analyse a specification sheet to identify suitable components for a given classroom need.
• Evaluate the benefits of modularity and upgradeability in desktop systems.

• Projector and screen
• Teacher laptop with presentation slides
• Printed handouts of component table and specification sheet
• Physical desktop (or disassembled components) for demonstration
• Worksheet for matching components to functions
• Whiteboard and markers
• Exit‑ticket cards

Begin with a quick poll: “What type of computer do you use at home and why?” Connect this to prior knowledge of laptops and tablets, then state that today’s success criteria are to identify desktop components, describe their characteristics, and interpret a spec sheet.

1. Do‑Now (5'): Short quiz on computer system categories displayed on the board.
2. Mini‑lecture with slides (10'): Overview of desktop components and their functions.
3. Group activity (15'): Students label a block‑diagram of a desktop using printed cut‑outs.
4. Live demonstration (10'): Teacher shows a real desktop, points out modular parts and discusses ergonomics.
5. Guided worksheet (10'): Learners match components to functions and calculate a simple performance estimate.
6. Check for Understanding (5'): Whole‑class Q&A using clicker or show‑of‑hands.
7. Exit ticket (5'): Write one characteristic that makes desktops suitable for school use.

Recap the main components and characteristics discussed, highlighting how modularity and cost efficiency benefit schools. Collect exit tickets to gauge understanding, then assign a homework task: research an online desktop spec sheet and write a brief paragraph recommending it for a specific classroom activity.
