These are posters you print and hang on your wall behind your desk or small group area. They are very helpful during quiet work times when calling on children with their hands up would be disruptive. Students put up the number of fingers indicating what the need and you can simply nod or shake your head when looking at them. This way is doesn't distract others, especially during reading and writing time where they need to sit quietly and concentrate. Black and white ones are available in my Back to School and Classroom Management Pack on TpT also.
