12 Days of Code


HISD is celebrating computer science with the 12 Days of Code in December, and we want you to join the fun!

Coding helps students solve problems, use logic, and think creatively, and it gives them a foundation for success in 21st-century careers. The activities on these calendars are online and unplugged and include designing an iPhone game, tracking Santa, decoding messages with cryptography, animating text and more.

Choose the coding calendar that matches your grade level in the top right corner of this page and engage in a new coding experience on each of the 12 Days of Code. You can even go beyond the 12 Days of Code and complete activities over the winter break. Once you complete an hour of code, scroll down to the bottom of the calendar to get your certificate of completion. Post a certificate selfie or a picture of coding activities at your school on social media using #HISDecoded. Happy Coding!
