I've been doing five paragraph essays with my 6th and 7th graders and they're really difficult for them. Some students get it, they just miss a sentence or two, but others write summaries instead of essays. I did an example essay with them, then they wrote one on their own in groups about a book of their choice, then when many of them didn't do so well on that, they corrected it and handed it in again. Then we did another one for the practice exam, but still many of my students don't seem to get that the idea is to make and sustain an argument, they wind up veering off into summary or just bland generalizations. Any suggestions?
