This article was very enlightening for me, since I have also taught second grade the past three years, and wondered how to incorporate social media into my classroom. The article mentioned posting to a Padlet wall. I have done this in my classroom, but it still doesn't get the students interacting with students around the world. Then, the article mentioned using a KidBlog and Twitter. I really like how they could post their science observations to Twitter using a class account instead of student accounts. I think this would make a great first step in introducing primary students to social media.
