Here's a pithy subject for other parents and teachers - I really would like to hear from teachers. I've been volunteering in a Yr 6 class at my daughter's school and every week the teacher has made some kind of mistake - be it a grammatical error, spelling mistake or a mistake in Maths. One example was where she asked pupils to put 4 fractions in ascending order and she gave them the wrong answer. I'm not so quick at Maths myself but thought it was incorrect and worked it out after I left. English is my strong suit - I was a book editor and English graduate - so I do know my stuff. But what should I do? I don't want to embarrass a teacher (and she's not the only one) and this particular teacher can be quite defensive. Should I let these errors go? Or raise them discreetly after class - but when it may be too late? Teachers/parents - have you experienced this situation and what would you advise?
