Scratch 3.0 Coding Lessons

Learn Scratch 3.0 step by step with 40 interactive lessons arranged in a clear path, 20 studios where you snap real blocks to solve challenges, 10 games you can play and then open as Scratch code, 15 tools to try blocks yourself, and 100 quiz questions that check what you understood.

✔ A structured learning path

Lessons are grouped into 8 units, from Beginner to Advanced: Studio Basics, Making Things Move, Looks & Sound, Loops & Patterns, Logic & Sensing, Data & Operators, Advanced Scratch and Game Design. Each lesson is short and focused, using cards, numbered points, steps and tips instead of long text, and every lesson includes a quick check question.

✔ Scratch-style blocks inside every lesson

Scripts are drawn as colored blocks similar to the editor: Motion, Looks, Sound, Events, Control, Sensing, Operators, Variables, Lists, My Blocks and Pen. In many lessons you can run the script on a mini stage, go through it one block at a time and watch the running block glow.

✔ What you will learn

The editor and the Paint Editor, sprites, costumes and backdrops, stage x and y coordinates and direction, motion and events, looks, effects and sound, loops and conditionals, sensing and user input, variables, lists and operators, broadcasts and clones, custom blocks and debugging, extensions, game loops, score, lives, levels and gravity, and how to save, share and remix projects.

✔ Studio: 20 studios, 60 levels

Build the script yourself from a palette of blocks, run it on a stage and reach the goal. Solve a level with fewer blocks to earn up to 3 stars.

✔ 10 games to play and remix

Apple Catcher, Sky Hopper, Brick Bash, Pop the Mole, Block Snake, Maze Escape, Paddle Pong, Star Defender, Memory Match and Desert Runner. Each game has a Scratch code tab that shows how it is built, plus remix ideas.

✔ 15 interactive tools

Sprite Sandbox, Stage XY Finder, Operator Lab, Color to Scratch, Polygon Calculator, Effects Preview, Random Tester, List Simulator, Glide Calculator, Animation Preview, Rotation Viewer, Key Event Tester, Layer Order, Block Finder and Project Ideas. Most lessons link to a related studio, tool, game or project, so you can learn an idea and try it right away.

✔ 20 quizzes, 100 questions

A quiz for every unit, plus Block Colors, Predict the Output, Find the Bug, Order the Blocks and Coordinates. Every answer comes with a short explanation.

✔ 12 step-by-step projects

Animated Name, Talking Story, Virtual Pet, Math Quiz Game, Drawing App, Coin Clicker, Racing Car, Space Dodge, Platform Jumper, Digital Clock, Fireworks Show and Chatbot Buddy. Build each project in Scratch and tick a checklist as you go.

✔ Block Guide

130 blocks, each with what it does and the lessons that use it, plus inputs and examples for many of them.

✔ Track your progress

XP and levels, a daily streak, 30 badges, bookmarks, search, and completion cards you can save or share. Your progress is saved on your device. Also included: an optional daily reminder, a home-screen streak widget, light and dark themes, and read-aloud for lessons when your device has a voice for your language.

Made for beginners in block coding, students and teachers. Start the first lesson, then apply what you learn in your own Scratch 3.0 projects.
