Great posters for classroom management! Students raise a number depending on which they need (ask a question, use the restroom, sharpen their pencil, or get a drink of water).
This helps me run a smooth classroom. While I am teaching or while I am working with students one on one (or in small groups), students can raise a number and I can signal them to go ahead without having to interrupt any learning! Great for foreign language students, as well as shy students!
Also find a rainbow version of this in my TpT store (also a freebie)
