I provide this checklist to my students when we begin our How To writing unit. On this checklist is everything that I expect my students to include in a how to writing piece. I laminate them and provide each student with a checklist and a dry erase marker. Before I conference with a student they have to make sure they go through their checklist before signing up for a conference. Please let me know if you want a version you can edit so you can adjust it to your own classroom.
