There is a list of codes to mark common student writing errors to help the teacher save time while evaluating compositions and essays. I have students double-space all writing so I can write the code directly above what they have written. Students then consult the grid and then notes and other resources to revise their work.
There is also a list of common expressions they will find useful while writing compositions such as "dear", "sincerely", "we have fun" etc
There's also a list of conjunction and transitional words like first, then, after, finally, etc.
