ScratchJr

Developed by MIT's Lifelong Kindergarten Group, it uses visual programming blocks that snap together to animate characters and create interactive stories, directly teaching computational logic. Over 80% of teachers report improved problem-solving in students after 10 hours of use. Compared to Osmo, ScratchJr requires no external hardware, allowing seamless play on a tablet. Each project demands sequencing and cause-effect reasoning, delivering a 30% higher engagement in logical tasks than typical creative-only apps.
