Computers are everywhere, but fewer schools teach computer science than 10 years ago. If you heard about the Hour of Code last year, you might know it made history. In one week, 15 million students tried computer science!

Code.org has developed the Hour of Code as a one-hour introduction to computer science, designed to demystify code and show that anybody can learn the basics. Sign up to host an Hour of Code this December 8-14 during Computer Science Education Week and help reach 100 million students by the end of the year.

Code.org will also send you awesome posters to hang in your school. If you did this last year, you know that students loved it. There are new tutorials for students of all ages and ones that require no computer at all.

Watch the video, and ask all educators (elementary and middle schools too!) to give it a try.

Code.org is giving every participating educator thank you gifts and 50 classrooms will win tech chats with special guest speakers. And in each state, one participating school will win $10,000 in technology for their school.
