ScratchJr

MIT's visual programming language, simplified for ages 5-7. Kids snap together colorful programming blocks to make characters move, jump, dance, and speak. There is no typing, no syntax errors, and no frustration — just drag-and-drop logic that teaches sequencing, conditionals, and loops through storytelling. ScratchJr is the single best introduction to computational thinking for young children, and it is completely free. The full Scratch platform (ages 8+) has over 100 million users.
