Hour of Code is a grassroots, teacher-driven, worldwide campaign to demystify computer science and offer a one-hour introduction to programming to tens of millions of students of all ages.  It’s organized by Code.org and an array of high-powered partners, and it’s designed to coincide with Computer Science Education Week (December 8-14).  Among the 27,112 classrooms worldwide that have already signed up to host events this year are classes in the following Newton schools:  Bigelow, Lincoln-Eliot, Mason-Rice, Memorial-Spaulding, Newton North, Solomon Schechter, Underwood, Ward, and Williams.  Any teacher or club leader can sign up to run an Hour of Code event using resources that include planning guides, videos, and self-guided tutorials for students.  Classrooms can win prizes that include video-chats with tech celebrities and grants for laptops, programmable robots, or other technology.  The Massachusetts Technology Leadership Council’s Education Foundation is partnering with Code.org to recruit industry volunteers to participate in Hour of Code in response to teachers’ requests.
