Scratch is a new programming language that makes it easy to create your own interactive stories, animations, games, music, and art — and share your creations on the web.
Scratch is designed to help young people (ages 8 and up) develop 21st century learning skills. As they create and share Scratch projects, young people learn important mathematical and computational ideas, while also learning to think creatively, reason systematically, and work collaboratively.
Scratch is available free of charge: go to Download.
Currently available for Mac OSX and Windows (see system requirements)
To access Scratch resources in languages from around the world, see Languages.
