got made to sit aside, protested briefly but did it, then sat quietly so says the lippy 14 yo 
she was immature" she's a child
Shes 14 not 10 and has been in senior school long enough to know how to behave.
lovely, removed from her classmates for a tiny thing. Teacher sounds pretty insecure.
She was distrupting the class. Why should the other children suffer?
Making he run around all lunchtime, not fair, making her run without a track suit, not fair, making her run around all lunchtime in front of the boys, unacceptable.
It wasnt all lunch time. She still had time to eat.
She was running that would keep her warm plus she plays hockey on a team so i doubt she wears a tracksuit then.
In front of boys......she goes to a mixed school. Her PE lessobs include boys so i am sure they would have seen her run before.
If the teacher screws up (as we all do) do they run around in front of the male teachers in their PE kit (I bet not!).
If a teacher behaves badly and does not follow the rules they get diciplined. This girl behaved badly didnt follow the rules and was diciplined. Same thing but you cannot apply adult rules to children. Thats daft.
I would have told my dd she was quite justified in not doing it, pretend her leg hurts! I hate this kind of punishment and this kind of teaching, it is why school is so crap for so many.
Great parenting skills. Teach them rules dont matter and you dont have to face the consequences of your actions. 
Schools crap when others disrupt lessons, bully, cause tension. Not because fair punishments are dealt out to those that deserve them.
