There is an EBD student that comes to class late every morning. Some days he walks in, and everything is just fine. Other days, he is upset and throws his backpack or slams his chair into the table. My cooperating teacher and I do what we can to prevent agitation when he comes in, but some days there's just no preventing an outburst...
Providing a quiet place to prepare is a good idea. Allowing the student a space to get through their initial reaction would prevent disruption in the classroom on bad days, and still allow them to stick to a routine on good days. Unless you are going to speak with the student and/or parents, there is no way of knowing how the mornings go before school.
I with this because these outburst are not part of acceptable behavior in the classroom.
