Reactive Classroom Moves
Teachers everywhere will sometimes have to manage a student who isn't fully in control of their emotions. Remember: she isn't a bad kid. There are no bad kids. These things happen.
In some cases you'll be able to spot a potential meltdown and take some proactive steps to avoid it.
But other times, your best case scenario is to remove the student so learning can continue - without eroding your relationship or credibility with the upset student.
