This has been playing on my mind and I'd appreciate views on whether it's acceptable
For background my daughter, age 10 / year 5, is very sensitive but also well behaved. She has increasingly been coming home upset saying the teacher made her cry. This is often based around whole class telling offs and often around tidying up. They have all been held off break multiple times for insufficient or too-slow tidying up.
On Friday the teacher said (dd would say shouted) that as some children hadn't tidied up he would keep them all there until they did - then he threw a pot of pencils on the floor. He kept throwing more pencils on the floor while demanding they all tidy up.
Knowing my dd she was probably tidying as fast as she could but even then she probably felt shouted at so got upset. Thing is if I tidied up and then someone deliberately made mess to make a point I'd go ballistic. But is this ok behavior for a class where presumably some of the children are avoiding helping?
