"Creative Commons is a non-profit that helps sharing and reuse of creativity and knowledge via free legal and technological tools . These tools are not alternatives to copyright laws, rather they work alongside them.
To help you better teach your students about Creative Commons and how it works, here is a handy graphic that visually captures the main important things students need to know about Creative commons. Enjoy"

This info is also good for teachers who sell products through TpT and Teacher's Notebook.
Actually good for faculty too!
