Students can run an essay or story through this snazzy, minimalist PowerPoint to hunt for and correct the most common mechanical, stylistic, and grammatical errors. Students use this tool to get that final polish on their work, as well as to learn (or re-master) proofreading and editing skills, and to approach their writing from a reader's perspective.
This PowerPoint could also easily be printed out as/adapted into a handout or a set of flashcards. I like working through the whole lesson as a group, so I can offer examples of each "problem" with students, and so we can troubleshoot examples students volunteer from their own writing.
The slides are based upon Andrea and Karen Lunsford's awesome 2006 research on the 20 most common errors marked on college students' papers by their instructors.
Enjoy--and please adapt to your needs in the classroom and/or grade level.
