ScratchJr is an introductory programming language that enables young children (ages 5-7) to create their own interactive stories and games. Children snap together graphical programming blocks to make characters move, jump, dance, and sing. Children can modify characters in the paint editor, add their own voices and sounds, even insert photos of themselves -- then use the programming blocks to make their characters come to life.ScratchJr was inspired by the popular Scratch programming language (scratch.mit.edu), used by millions of young people (ages 8 and up) around the world.
In creating ScratchJr, we redesigned the interface and programming language to make them developmentally appropriate for younger children, carefully designing features to match young children's cognitive, personal, social, and emotional development.ScratchJr is available as a free app for both iPad and Android tablets.
