My teacher uses a Noise Meter similar to this one. The Noise Meter is a cool way to remind students the correct noise level that they should be using! You just use the paper clip and move it to the appropriate noise level the students should be using.
Simply print out the owls write the child's name then cut them out. They can be put on lockers, backs of the chairs or as a door decoration. There are colored ones or black and white ones. The black and white ones could be a first day activity for the children to color, cut, and write their name on the tag then put it up on the doorway.
