Block-Based Coding

Block-based coding enables you to create your own programs by snapping code blocks together. We encourage you to tinker, iterate and change your program as you learn and develop your ideas, and experiment! We designed the Scratch graphical programming blocks so that you can focus on what you are creating, not on the syntax of traditional programming languages.

A special message for you from the Scratch Team

Get Started with Scratch

Check out the Scratch Coding for Climate Playbook you can download here to get started with Scratch. This playbook focuses on creating building solutions to real-world sustainability challenges using the objects you have around you! Then, create a Scratch project that incorporates the model, bringing to life ideas on how to integrate sustainable elements. Find links inside the playbook to coding cards for tips and more!

Or check out our Imagine a World tutorial, which invites you to create Scratch projects inspired by your imagination: what if people could fly, or animals could talk? Try it out in the Scratch project editor, explore the educator guide, or see our coding cards for tips.
