This is a voice level chart for your classroom. The levels go from 0-4. At level 0, the students are silent. At level 1, the students whisper. At level 2, the students speak in their normal voice. At level 3, the students use their presenter voice. At level 4, the students use their outside voice. When I use this in my classroom, I tell the students what voice level they should be on. As a visual reminder for the students, you can place a magnet or other item to mark the voice level that the students should be on.
