The pdf lists examples of the applications and add-ons which can be used in the classroom to support the implementation of the 4C's, which support common core. 

The 4Cs (Communication, Collaboration, Critical Thinking, and Creativity) all support each other and in a well planned lesson, are all being used while students complete a specific learning objective. 

These applications can be used on the chromebooks and will help mix things up in the classroom for students and teachers to learn and do their best.
