The 50 most common errors in students' essays: on one side organized 1-50 and on the other side organized according to the Six Traits of Writing.
I make a variation of this handout every year. When grading essays, I now circle the error and write the number of the error in the margin, students have to reference the sheet when they get back their graded essays and highlight the coded error, This process makes them take an active approach to understanding their grades. They then must make a short list of their most common errors to avoid on their next essay.
The first time I use the list, I have to reference the error numbers often but I quickly get used to it and it ends of saving me so much time when grading WITHOUT sacrificing the detailed level of corrections to the students' essays.
