Show and Tell: Explaining Your Code Like a Real Programmer
Real programmers do not just write code and walk away. They show their teammates what they built and explain how it works! This is called a 'code show and tell,' and grown-up coders do it every single day at their jobs.
What You'll Learn
- How to describe what your code does, step by step - Three magic words coders use: input, action, output - How to point at your code and 'read it out loud' - Why sharing your code helps you get better and better
Input, Action, Output
Every program does three things. INPUT is what goes in, like clicking a button or typing your name. ACTION is what the code does with it, like adding two numbers. OUTPUT is what comes out, like a sound, a color, or a message on the screen. If you made a block program that says 'MEOW' when you press the green flag, the input is pressing the flag, the action is the computer checking your blocks, and the output is the word MEOW appearing.
Pointing and Telling
When you show your code, point to each block or line with your finger and say what it does in order, like: 'First this happens, then this happens, then this happens.' You do not need fancy words. 'This block makes the cat move' is a perfect sentence.
Whisper your explanation to a stuffed animal or a pet before you tell a real person. It helps your words come out smoother!

My Code Show and Tell
Pick any small program or set of blocks you have made (even 3 blocks count!). Draw or write down: 1) what the INPUT is, 2) what ACTION happens, 3) what the OUTPUT looks like. Then explain it out loud to a family member using those three words. Deliverable: a one-page drawing labeled Input/Action/Output plus a checkmark once you have explained it to someone.
