This document was created specifically for how-to essays. I gave my students the How-To Checklist as they wrote their essays to make sure they met the requirements for the content and conventions. They were asked to read their own essay and check off how well they met each requirement. If they needed to make any changes, students recorded that information in the "comments" section. This could also be used for peer reviews.
The grade sheet is, of course, used to assess the essay after students submit their final copy. I made sure to include the same requirements that were on the checklist so there are no surprises!
