Aha!/Mmhmm/Say what?

Groups divide paper into three sections.  Aha! is something that they hadn't realized or thought of before but they like.  Mmhmm is something they had thought of before but agree with.  Say what? is something that they do not agree with from the article.  It's a focused discussion that draws people back into the text.  It allows people to air concerns they had about the reading or places they thought were strange or particularly interesting.  Individuals could also do with post-its as they read.
