Scratch
Programming through play
MIT's Scratch teaches programming through visual block-based coding, introducing millions of children to computational thinking.
Scratch replaced typing code with snapping blocks together. MIT’s Media Lab created a programming environment where children could create interactive stories, games, and animations without syntax errors or cryptic error messages. Blocks physically connect only in valid ways. The result: millions of young people learning programming fundamentals through creative expression.
