Classrooms atmosphere

The atmosphere of Mrs. Montoya's 4th-grade class is positive, from what I've seen the students seem to like their teacher. I always see them raising their hands and paying attention to what she has to say. I haven't got the chance to see her actually teach because the time we come in on Thursday is their study time. During this, they're respectful and finish their work in silence with occasional side conversations. Though these students are good to their teacher they're not always as respectful with their peers. Today we had an administrator come into the classroom to talk about a stolen stuffed spider. They were asked to write down anything they knew about the incident, in order to find the thief. Hopefully by next week when we come to visit again the stuffed spider is returned to its original owner.
