What Is Scratch? A Visual Coding Guide for Kids

Scratch is a free, visual programming language created by the MIT Media Lab that lets children build games, animations, and interactive stories by snapping together colour-coded "blocks" instead of typing code. Because there is no syntax to memorise and nothing to spell wrong, Scratch is one of the most popular first coding tools in the world, with more than 90 million registered users. It is designed mainly for ages 8-11 but works well for anyone starting out.

How Scratch Works

Scratch replaces written code with drag-and-drop blocks that lock together like puzzle pieces. Each block is a command — "move 10 steps", "play a sound", "when green flag clicked" — and stacking them in order tells a character, called a sprite, what to do. Because mismatched blocks simply will not connect, kids cannot make the kind of typing mistakes that stop traditional code from running.

A child might drag a "when space key pressed" block onto a cat sprite so it jumps whenever the space bar is tapped — the first step toward a full platformer game. Projects run instantly in a web browser, and every project shared on the Scratch website can be "remixed", letting kids learn by opening and changing what others have made.

Why It Matters for Kids

Scratch builds computational thinking — breaking problems into steps, spotting patterns, and fixing mistakes — the same STEM foundations Malaysia's KSSR curriculum encourages. It gives children an early, confidence-building win before they move on to text languages like Python. Structured Algonova coding classes guide kids from their first Scratch project to real programs, and our guide to coding languages for kids shows what comes next.
