Boards and Pins

Pinterest Boards or Pins you feel would benefit others to connect? Since I am an educator, author, college professor, and librarian, I will focus on educator boards or pins.  Wow, there are a lot! My only thoughts on this immense wealth of shared knowledge is that copyright is not a big focus, which is important in my realms of thinking.

Here is one good link to different boards for different public school grade levels: https://www.pinterest.com/teachers/
Of specificity, one can find a board on simply sight words with many pin options, reading and writing lessons, readiness lessons, crafts, literacy activities, math activities, and so many more classroom supplements.

For the either the public classroom or for an academic classroom, the instructor could post the course needs, syllabus, post links, timelines, and perhaps have a meeting place of student minds where students can discuss, as seen in the following link: https://s3.amazonaws.com/infographics/How-Educators-Use-Pinterest-800.png 

Those were just two links.  What are some other ideas you may have and what about that valued over time copyright?
