Thank-you feenie for defending me. I can brush off bitchy comments from anonymous strangers online. People seem to think the barrier of the internet gives them free rein to be far more unpleasant than they would be in real life.
To be clear: I did not, at any point, say that I would stop a child from using a method simply because I didn't like it. I would, however, ask parents to not contradict what is happening in the classroom as it confuses their child.
As an example, I have a lower ability child whose mum doesn't understand our methods. I spent 30 minutes after school with her, showing her how to add and subtract on number lines, and how to solve multiplication and division by repeated addition and subtraction. She was very thankful that I had shown her, as she had only been taught column methods, and although these do get an answer, for a low ability child aged 8, it is not the best method to be using. Said child doesn't get the relative size of numbers, and so she will not know when her answers are wrong.
A point to the teacher bashers on here- we teachers come here to try and offer help and advice. We do this in our spare time, and (at present) our holidays. There is no incentive to us other than to try and share our knowledge and help others.
I appreciate lots of parents have little knowledge of what happens behind the school gates, and I appreciate this would make anyone anxious, but the educators here are trying to explain what happens. Being snapped at and insulted is not going to get a positive response, and it just means people will stop replying.
