pinterest

I have a personal pinterest account already and find it very helpful in my career and personal life. I have several boards including one called "teaching" where I pin lots of great resources for the classroom. I'm curious how the security features would work if you wanted to create a Pinterest account for your classroom and allow students to share on one board. Obviously students would have to create a Pinterest account, so I'm curious for elementary students how that would work so that the pins they were looking at would be school appropriate. For example of you made a shareable board for students to post research sites on the Westward Expansion.
