For example, in Ms. T's class students regularly do group stations. The stations are math on a computer, writing spelling words on small whiteboards, writing about a specific topic in their journal, and individual reading. Each of these stations is numbered. The students know the number of each station because it is always the same, and they each drew a popsicle stick to show where to start. Mrs. T has an alarm that goes off when it's time to change stations. When students get too loud, he rings a bell, but he will only ring it a certain number of times before the group's time ends. By setting up the stations early on, children know what they are supposed to do and how they are supposed to work. He also manages their behavior by having a bell to keep them quiet. Another example is that in Mrs. A's classroom the students have to raise their hands to speak out loud. He won't recognize them until they raise their hand. Finally, in domain two the teacher should organize their physical space. For example, Mrs. A keeps her desk very clean and puts things in drawers and filing cabinets where she can easily locate them. It also keeps her classroom organized as a whole. There are shelves throughout the room that are labeled with what's on the shelf. Some shelves have tubs and the tubs are labeled. What the labels say is there, it is there. It has a shelf for books for students to use and all books are kept tidy so they are easy to read
