I love Pintrest!
I think that it is a great site that teachers should us to help guide them through out the year.  Technology is always changing, so its so important to teachers to stay FRESH and current with new technologies and teaching ideas.  Its a fablous place to post projects, assignments, activities, and much more for other teachers to learn about! 
Check out my pintrest blog that I have put many usefull teaching things to help me in the future when I become a teacher!
