Awesome site for Blogging - things to remember when teaching students how to respond. There is even a pdf file available that the teacher has created. On this paper, students are given sample blog responses and discuss whole class whether they would approve the comment.
I wish I would have seen this post yesterday. I had to reteach blogging to our book club group. Mainly, I feel the time constraint/computer issues we had the first two weeks set us back. However, I did something similar to this actually handwriting responses on the white board. The number of posts and details within the post increased dramatically.
Money Word extension - this is similar to the other one I posted, only in this game, students make up words and determine their money value. Extension.
