What Is Code?

Computers only do what we tell them. Code is how we talk to them — let’s meet Robo!

🎯 What you will learn

  • Code is a list of instructions
  • Computers follow instructions exactly
  • People write code to make apps and games

👋 Let’s get started!

Meet Robo the robot! 🤖 Robo is super fast, but Robo can’t think for itself. Robo only does EXACTLY what you say. The instructions we give computers are called CODE. Let’s learn to talk to Robo!

🪜 Step by step

1. 🗣️ Instructions

An instruction tells someone what to do, like “clap your hands” 👏. Code is just instructions for a computer.

2. 🎯 Be exact!

If you tell Robo “make a sandwich”, Robo is confused. You must say each tiny step: get bread, open jar, spread, close.

3. 🎮 Code is everywhere

Every game, app and cartoon on a screen was made by people writing code. Someday that could be YOU!

🎨 Unplugged activity

🧍 Play “Robot Says” with a grown-up! One person is the robot and must do EXACTLY what the coder says — no more, no less. Try getting the robot to walk to the door. Then switch!

Help Robo wake up!
