Hi
I have just been reading all this thread and feel for you, I really do, it is a horrid situation.
Firstly, we have a school similar to this near us, that is owned by the head and founded by her parents, what she says goes and many people have left because she is inflexible. It is a case of if your face fits, you are OK, if not then you might as well move on. I wonder if this is the case with your school?
Anyway, I digress! It sounds to me as if there are two issues, one is the accusation of your dd, which is ridiculous at their age and the other the teachers attitude to your dd, which probably has prompted the accusation.
I would firstly write down what I want to say, If you are anything like me, when under pressure, all normal thinking goes out the window!!
I would stress that you agree that the incident shouldn't have happened etc. etc., but your dd doesn't know the value of money and maybe explain the game and how it should work, concluding that you have had words with her and as far as you are concerned that is the end of it. (my dd at 5 didn't understand the value of money, no chance!).
I would then go on to say that you have other concerns about your dd, that you would like to discuss with them. Personally, I would hope this would throw them a little, as they may probably want to raise stuff with you!!
I had a similar thing with my dd in Reception and I sort of got around it by saying that I realise my dd is chatty and can be a bit enthusiastic and she is the sort of child that you will either love in your class for the enthusiasim, or hate for the constant questions and chat and perhaps the teacher found the latter (she told me that she actually loved dd and she was a breath of fresh air, which sort of threw me a bit!!!!)
You may find they come out with a number of issues back, which you will need to listen to and hopefully be able to address, but whatever they say, it is so important to keep calm to discuss what is going on, because it unless it is all 'out in the open', you are never going to feel happy about it. I would definately mention about the teachers comments and that you felt these weren't appropriate in front of your child and certainly not the other parents and children.
I would also ask, if they are not happy with your dd's behaviour etc., what do they expect and what steps will be put in place to achieve this? or want you to do?
Finally, I agree with a few of the others, your trust in the school seems to have broken down and maybe looking for something else is an option. Possibly in September a different teacher will change things completely, but is it fair on your dd to keep her there in the time being?
If it was me, I would look for another school asap and my trump card if they were unreasonable, would be to tell them to stuff it and give them notice!
Remember, you are the customer here, they are the service provider, they need you, more than you need them and in the current climate, they need all the parents fees they can get!
Best of luck, you will probably find that you have gone over it so much, that in your mind it is a big thing (which of course it is to you as a parent), but to them it is just a small thing and will be completely different from what you are expecting!
Best of luck
