First, choose a model of how you will structure your stations: Skill Stations, Daily Five, Blended Learning, something else? It will help to be consistent so that students can practice established routines.
Choose activities based on your current topic of study and students' needs.
Keep in mind: The process of learning is more important than creating a product at each center. Students need to be accountable for work completed, but there does not always have to be a product.
