Lesson Plan

• Describe the function of input and output devices and give examples.
• Compare data‑flow direction and conversion processes for input versus output devices.
• Identify devices that serve both input and output roles.
• Explain how analog signals are transformed to digital and vice‑versa.
• Apply knowledge by correctly classifying a list of devices.

• Projector and screen
• Whiteboard and markers
• Printed worksheets with matching and quiz sections
• Physical examples: keyboard, mouse, scanner, speaker, monitor
• Diagram handout showing data flow (input → CPU → output)
• Index cards for classification activity

Ask students to imagine how they tell a computer what to do and how the computer shows the result. Recall that they already know the basic parts of a computer (CPU, storage, etc.). Explain that today they will learn to differentiate input and output devices and how data moves between them, which will be the success criteria for the lesson.

1. Do‑now (5'): Matching worksheet – match device pictures to “input” or “output”.
2. Mini‑lecture with slides (10'): Define input devices, give examples, discuss analog‑to‑digital conversion.
3. Interactive demo (10'): Show a keyboard, mouse, and scanner in action; highlight data flow to the CPU.
4. Group classification activity (15'): Teams use index cards to sort a mixed list of devices into input, output, or both; teacher checks understanding.
5. Quick quiz & exit ticket (5'): Students answer four short questions on a quiz sheet; collect for assessment.

Summarise the key differences in function, data direction, and conversion for input and output devices. Students complete an exit ticket stating one new thing they learned and one question they still have. For homework, each student creates a three‑item table of personal devices, labeling each as input, output, or both.
