Hour of Code Unplugged Activities (No Computers or Wi-Fi Needed!)
By Dr. D (Dhomas Hatta Fudholi) · Professor of Informatics & Author of Zeno's Coding Adventures Complete Classroom Series
Why Teach This Computer Science Concept Screen-Free?
Running Hour of Code (CSEdWeek), a STEM rotation station, or an emergency substitute lesson for 1st, 2nd, or 3rd graders—without enough charged Chromebooks or reliable Wi-Fi? Our unplugged coding packet lets every student participate immediately with just a pencil.
Teachers love unplugged coding because zero class time is wasted on forgotten passwords, browser glitches, or distracting games. Students collaborate, talk through their logic out loud, and take home a completed coding packet they are proud to show their parents.
