Appropriate mostly for Key Stage 2, Scratch is a programming language that makes it easy to create your own interactive stories, animations, games, music, and art — and share your creations on the web.
As young people create and share Scratch projects, they learn important mathematical and computational ideas, while also learning to think creatively, reason systematically, and work collaboratively.
