Input and Output

👩‍🏫 Teacher’s Guide

Objective

Students will explain input and output in programming and identify examples like typing, clicking, and showing results on a screen.

Teaching Notes

• Connect to earlier lessons: input-process-output.
• Use examples: pressing a key (input) makes a character appear (output).
• Explain that programs can ask questions and display answers.
• Keep examples block-based and beginner friendly.

🧒 Student Worksheet

• — Information a program receives from the user or device.
• — Information a program shows or produces.
• — An action like a click or key press.
• — To show something on the screen.
• — What the program does after input.

Computer Prtactices

• Input/output sort: Press key, show text, click mouse, play sound, show score.
• Design a button: Draw a button and write its input and output behavior.
• Act it out: Student is program—partner gives input; student gives output response.
• Create 3 event-response pairs (click → change color, key press → move).

Reflection

• What is one input you used today?
• What output did you see?
