Computer Science week is next week - December 8-13, 2014. Each year an "hour of code" is encouraged in schools across the USA to allow all students to have exposure to the basics of computer science and programming. Do you have to know how to program to host and hour of code for your students - NO! Many resources are available to make coding and beginning computer science a breeze for you and your students.
