THINK Digital Citizenship Poster
Here is a document that educators can use to inform kids of the need to be aware of what they post online. 
Before they post, they should ask themselves 5 questions:
1. Is it True?
2. Is it Helpful?
3. Is it Inspiring?
4. Is it Necessary?
5. Is it Kind?
As a class, teachers could print this poster and have kids sign it as a pledge or "contract".
