I laminate these posters together and each student has a clothes pin with their name on it. As the student moves through the writing process they move their clip to where they are stopping for the day. The next day they can look at their name to remember where they left off and I can see where they are too. This also allows the student to go at their own pace.
I also color coordinate everything...for example, the think poster is orange so the paper they use to write ideas is in an orange basket.
