Case
Severe EBD

This student is in 1st grade. He is intensely aggressive when a situation or command triggers him. This student will aggress on himself, students, and staff, elope, and enter a mindset that is completely unreachable. He is an extremely lovable, sweet, and predictable child, in that he loves Pokemon and drawing. The classroom becomes unsafe on a daily basis and minimal learning is happening due to the constant occurrences from this student. There are 11 students in the class, an Instructional Assistant and the ESE teacher.

Solution #1
I think it could be helpful to work with the school's behavior specialist to establish a plan for the student. If anything the specialist could take the time to work with the student so that the teacher instructional assistant can continue with the lesson or working with the other students. I have also found that behavior specialists can work with teachers to track student behavior (like their reaction to situations and commands), the data can help the teacher adapt these things so that the student does not become aggressive.
Solution #2
One thing that may help would be for the student to create a daily schedule or checklist for himself to follow with the help of the teacher. The student will be able to have a say in what he does and the teacher will not have to tell the student what to do every time the class changes lessons or activites.
Solution #3
I think that talking to both the student's parents and guidance counselor and employing some sort of plan in will help intervene in the student's aggressive and unreachable behavior. Together, you can pool the resources to help reach this student!
Solution #4
Perhaps reach out to someone who is a professional in dealing with behavior, especially when it starts to affect other students as well and the staff. You can also incorporate ways to calm him down with his drawing or Pokemon- like as a reward after doing something.
Solution #5
I believe working with the behavioral specialist at the school is your best option. You should always give plenty of praise to the student for staying on track. Also have a lot of patience.
Solution #6
It's as if you are writing about my student. I have no idea what to do with him. My partner teacher and I switched his homerooms and that seems to be helping, plus his parents are finally taking the initiative to get him into therapy and get him medicated.
Solution #7
In my experience working with 1st graders who deal with EBD struggles, building a rapport and relationship with them is foundational. Going along with this is establishing a no-tolerance for certain behavior right away so that they know that these things are unacceptable without any negotiation. If you display interest and genuine care for them, they will not want to disappoint. Given their condition, situations will inevitably arise but this foundation will minimize the situations and will make correcting them an easier process.
Solution #8
I would strongly consider looking at the students IEP and considering a more restrictive environment. I think having the student in the classroom setting they are in now is not helping the student, or other students around them.
Solution #9
I would have a room where your class could go if needed during these outbursts for safety and so that you can continue on with your lesson. If it is possible the child would need to be removed for his and everyone else's safety to a separate room where he can calm down
