Lesson 1: What Is Coding?
Coding is giving instructions to a computer. Computers do exactly what you tell them — no more, no less! In this course, you'll learn to give instructions using colorful code blocks that snap together like puzzle pieces.
Key Concepts
Instructions
A computer follows instructions one at a time, in order. If you tell it to hop, then clap, then spin — it does exactly that, in that order. This is called a sequence.
Algorithms
An algorithm is just a list of steps to solve a problem. A recipe is an algorithm! Your morning routine (wake up → brush teeth → eat breakfast) is an algorithm.
Why Coding Matters
Coders build the apps on your tablet, the games you play, and the websites you visit. With coding skills you can build almost anything!
