CS Fundamentals for grades K-5 | Code.org Code Studio

Code.org has developed an elementary school curriculum that allows even the youngest students to explore the limitless world of computing – at no cost for schools. The courses blend online, self-guided and self-paced tutorials with “unplugged” activities that require no computer at all. Each course consists of about 20 lessons that may be implemented as one unit or over the course of a semester. Even kindergarten-aged pre-readers can participate.
