I'd like to recommend the Writing Strategies Web Site. Jim Collins of the University at Buffalo has created a website worth your attention. This is a rich resource for information about 6-traits, the writing process, and writing across the curriculum. If you need classroom poster materials, teaching ideas, or advice on how to teach the traits as part of the writing process, this site will be a treasure chest of goodies for you.
You'll be able to download a series of fourteen traits specific PDF files. These files are richly illustrated and would make a great writing center display, or presentation set for an in-service.
Here's a clever presentation of the traits and the writing process:
This diagram shows how you might roll out a traits based writing process in your classroom:
Take the time to visit this site! You'll be glad you did.
