Basic Coding with Scratch
With Scratch, you can program your own interactive stories, games, and animations — and share your creations with others in the online community.
Scratch helps young people learn to think creatively, reason systematically, and work collaboratively — essential skills for life in the 21st century.
Scratch is a project of the Lifelong Kindergarten Group at the MIT Media Lab. It is provided free of charge.
