AIBU to find it odd a teacher said this without explanation?

[Meltinghereokay]

Dd, 7, told me today that the teacher told her she’d been naughty but she didn’t know why.
She said she had lots of papers with kids names on (around four names, including Dd’s ) and read out their names and said they had been very naughty today. She didn’t say why or what they’d done. Dd doesn’t know why and says she wasn’t told off for anything

Does this seem odd

Yes exactly

If I had a quid for every child who said they didn’t know why they were being told off , even when I have reminded them several times and explained to them in detail, sometimes only 30 seconds before, I d be a very rich person.
What children usually mean by “ I don’t know why’ is ‘I do know but I don’t agree and my justification for doing it should override the teacher’s opinion and/or the health, safety or environment for learning of the rest of the class.’
By all means ask the teacher what DD was doing, but she wouldnt have mentioned her behaviour if it hadn’t been an issue . I’d put my money on talking over someone else or not following instructions.

I’ve seen teachers do this… they’ll tell the children that they’re going to write down the names of the children who are perhaps being a little silly or disruptive. I think it’s a way to acknowledge the behaviour without disrupting the whole class lesson.

If this happened at all, most likely it was part of some role play for English or PSHE. I probably wouldn’t bother to chase it up at all, but if I did I’d just casually mention it on the gate and see what the teacher said. I certainly wouldn’t assume the teacher was doing what your daughter described as some sort of discipline thing, unless you know for a fact she’s got form - that would be really weird.
