Classroom management...cutting down on interruptions

One thing I love having in my classroom is "Hall Passes".  Students will grab a pass depending on where they are going, place it on their desk, then leave the room.  This stops a lot of interruptions when I am working 1:1 with students.

This is an example of the Library pass my students will place on their desk.  

I printed them, cut them out, and then laminated them.  They hang on a hook at the front of the room so students know where to find them.
