I currently use this sign in my classroom to inform students when I am busy and unable to answer their questions at a specific time. I typically put up this sign when I am either conferencing or working with a small group of students at my kidney table. This allows students who I am not meeting with to know I am busy and cannot talk at the moment. This simply tool helps me to stay focused on my current group of students while being clear about my expectations. All you need to do is print, fold horizontally, and laminate and this sign will be ready to use in your classroom.
