MOstly math and SS lora - I didn't make the schedule. The teachers made the schedule for me. I just started this job 2 weeks ago. I go to two classes a day. The student receives a positive from the teacher which tends to help slow down misbehavior.
Ultimatums force a confrontation which usually go against the teacher.
You can restate the rules and request compliance. Salaries depend on each state. I went to Iowa State University. I felt I was prepared. Most students in middle school will see the ultimatum as a challenge and take you up on it.
