Scratch is a slide-and-drop programming language for children.[1]

It allows them to explore and experiment with the ideas of computer programming by using "blocks" that are put together to make simple code.[2]

Although made for children 8-16[3], Scratch can be used to produce simple or complex programs so it is worth learning to use by adults as well.

Scratch is translated into 70+ languages and is used in homes, schools, and after-school clubs in every country in the world.[4] Scratch is often used in teaching coding, computer science, and computational thinking. Teachers also use it as a tool across many other subjects including math, science, history, geography, and art.
