Scratch coding for kids: a beginner's guide

Scratch is a free, block-based programming language made by the MIT Media Lab. Children snap colourful blocks together instead of typing code, so there are no syntax errors to trip them up — which makes it one of the friendliest ways for a child to write their first program. It suits most learners from about age 8, and you can start today in a web browser at scratch.mit.edu.

What is Scratch?

Scratch is a visual programming language and online community created by the Lifelong Kindergarten group at the MIT Media Lab. Instead of writing lines of text, children drag and connect labelled blocks — "move", "wait", "repeat", "if" — to control characters called sprites. With those blocks they build animations, games, quizzes and interactive stories, then share and remix projects with other young makers. It is free and runs in a browser, so there is nothing to buy or install.

How block coding works

Each block is a ready-made instruction shaped like a jigsaw piece. Children snap blocks together top-to-bottom, and the program runs in that order. Because the blocks only fit together in valid ways, a child cannot make a spelling or punctuation mistake that stops the program — the two things that frustrate beginners most in text coding simply do not happen. That frees young learners to concentrate on the idea: what should happen, and in what order. It is why block coding is such a strong first language. The logic children learn here — sequence, repeat, decide — is exactly the logic they will later type out in languages like Python.

What age is Scratch for?

Scratch is designed mainly for ages 8 to 16, and confident younger readers can enjoy it with a bit of help. For children who are not reading yet, MIT makes ScratchJr, a free tablet app for ages 5 to 7 that uses picture blocks instead of words. A rough guide:

• Ages 5–7: ScratchJr — picture-based blocks, no reading needed.
• Ages 8–16: Scratch — the full block language at scratch.mit.edu.
• Around 11+: many children are ready to begin typed, text-based coding such as Python alongside or after Scratch.

First project ideas

Start tiny and finish something — a completed project builds far more confidence than a big one left unfinished. Three friendly first builds:

• A chase game. Make one sprite follow the mouse pointer and a second sprite run away. Add a "when they touch" block to score a point or play a sound. Children meet events and collisions in one short project.
• An animated name. Put a letter sprite on screen, then use repeat and change colour / grow blocks so the name wobbles, spins or sparkles. A gentle introduction to loops with an instant, visible result.
• A quiz. Have a sprite ask a question, then use an if/else block to say "Correct!" or "Try again" depending on the answer. This brings together input, decisions and variables for a score.

What coding concepts it teaches

Behind the colourful blocks, Scratch teaches the same ideas used in every programming language:

• Sequencing — putting steps in the right order so a program does what you intend.
• Loops — repeating actions without copying blocks over and over.
• Events — making things happen in response to a click, a key press or two sprites touching.
• Variables — storing and updating values such as a score or a player's name.

These are transferable skills. A child who understands a loop in Scratch already understands the idea of a loop in Python — only the way of writing it changes.

When to move on to Python

Scratch is a brilliant start, but at some point blocks start to feel limiting. When a child is comfortable with loops, decisions and variables, is happy reading and typing, and wants to build things that go beyond what the blocks allow, it is time to try text-based coding. Python is the usual next step: it reads almost like plain English, it is used by real scientists and companies, and it keeps the same logic a child already learned in Scratch — they just type it instead of dragging it. Our Python coding for kids guide explains how to make that jump.

Is Scratch free?

Yes — Scratch is completely free at scratch.mit.edu and runs in a web browser, and ScratchJr is a free app for tablets. Kids Learning Hub does not host Scratch itself; for block coding we point you to the official MIT site. What we offer, free, is the next step — typed code. Our courses teach real Python and web development (HTML and CSS) in the browser, so when your child is ready to move beyond blocks, there is a free, structured path waiting.
