This summer I am doing this...she takes you step by step organizing your classroom (starts with materials needed to do so... great site)
This "I'm done..." board is a great way to remind students of their choices once they have completed the current activity. By having this posted as a bulletin board or poster within the room, students would have a visual reminder of the acceptable options they have while awaiting transition to the next activity. This procedure would help maintain order as well as keep faster students busy.
