I have a student who has frequent meltdowns. Most days he has one or two meltdowns that don't last long, maybe 5 minutes at most. He'll sob, kick the desk, stomp his feet, slam his pencil case, etc. The class knows to ignore his behavior as I fumble through a lesson. It's difficult. But some days he just loses it, like today. He was screaming bloody murder, slamming his fists, etc etc, and the look in his eyes was like he wasn't even there. I'd call it an 'anger blackout.' Normally I call the office for help, but today there wasn't time - just 3 or 4 minutes until the dismissal bell. I barely got him in the hallway without having to touch him (I am VERY scared to touch students), and I got down on my knees and tried to find out what set him off. I never could get him to speak coherently before his ride came, but it seems to have something to do with a pencil and someone borrowing it without asking. I told his step-dad what happened in carpool, and told the boy I would be writing an office referral for interrupting the lesson, and he clenched his fists and jaw, tears streaming down his face. I feel like I'm failing this student and handling his outburst all wrong. Advice?
