Each day a new table captain will be assigned. This is a good way to teach leadership to students. In my classroom, the table captain will be responsible for distributing papers, making sure the table is prepared and anything else that I may decide.
This voice levels poster is used in most preschools during my placesment, I think it is an effective way for teachers to control the voices in the kinder. Child also remember the colors and related voice levels that they should use inside and outside.
