Communication - I have used Edmodo for years in my fifth grade classroom to communicate with students and parents. You can post photos and assignments. Even though I haven't taught fifth grade in four years I still use Edmodo to communicate with my former students!
Collaboration - Our district uses Google Drive to make collaboration easier. We also have Team Drives for particular members to use.
Creativity - As a Teacher Librarian I have used Animoto with students to create video book trailers. It is a quick and easy way for students to create short videos.
Critical Thinking - This year we used Scratch to teach students the basics of coding. I would also add code.org and Kodu to this list.
Organization - I currently have 2 Symbaloo pages - one for my personal use and and a library page for my elementary students.
