ScratchJr

ScratchJr delivers the fastest path to computational thinking for ages 5-7, using colorful programming blocks that kids snap together to animate characters. No typing or syntax errors exist — just drag-and-drop logic teaching sequencing, conditionals, and loops through storytelling. This MIT-developed app outperforms #5 DragonBox Numbers in teaching foundational logic without math prerequisites, and it is completely free. The full Scratch platform (ages 8+) boasts over 100 million users, validating its global appeal. With zero cost and a proven 30-minute learning curve to create a first animation, ScratchJr is the definitive introduction for young coders.
