CS Unplugged

CS Unplugged is a free collection of hands-on activities that teach computer science ideas—like algorithms, sorting, binary numbers, and error detection—without screens. Using cards, string, paper, and games, kids experience core concepts physically and socially, which can be especially powerful for mixed-age groups or tech breaks. Parents and teachers appreciate the detailed lesson write-ups and low-material requirements. As a zero-cost, high-engagement resource, CS Unplugged is perfect for adding depth to coding units or introducing CS where devices are limited.
