Scratch User Guide: Introduction

Introduction

What is Scratch?

Scratch is an easy-to-use programming language that allows anyone (even beginners who have never programmed before!) to create their own interactive stories, games, animations, videos, art, and music on the computer. Scratch was developed by the Lifelong Kindergarten Group at the MIT Media Lab, and is available for free.

Scratch can be used to create just about anything you can think of. To get a sense of the range of things people make in Scratch, take a look at the various projects posted online at the MIT Scratch homepage. Figure 1, below, also shows a sample Scratch project.
