What would you think about this scenario:
Several year 6 children are kept in at break time because they didn't finish their corrections to their work. My child says that he completed his work, then his teacher told him it wasn't good enough and their were several things to change, including a couple of misspelled words. But she didn't give him the correct spellings, he had to look them up in a dictionary, and because he had the third letter of the word wrong he couldn't find it in the dictionary. So he missed all of his break time.
As you can imagine there is more backstory about this teacher, but just taking the event on its own, is it ok to keep a year 6 child in at break for this? I would completely understand if he was kept in because he hadn't done his homework, or was messing around in the lesson, but this appears to be just kept in because he hadn't done the work to the standard she required.
