Thank you for your responses.
Anoushka - thank you for your interest, I wasn't intending to go into how the maths could be used, but it's a valid point. It's intended to be more of a "how to do ..."
noblegiraffe - I suppose it is intended to be a kind of "self-help" book, there are plenty of textbooks and revision guides already, and good ones. The more I write it the more I'm conscious of the intended user - I started out writing it for students, now I'm thinking of making it for parents - maybe I need to do both, hence my question here.
ExitPursuedByA Bear - I could pop round (jokes) but if I write the book then maybe I wouldn't need to, and it would help lots of people.
thornrose - difficult to say without knowing exactly what your daughter finds difficult, but it is not intended to cover special needs, more mainstream secondary to GCSE. However, I'm trying to explain the content really clearly to aid understanding.
marcopront - as I said above, I'm kind of pigeon-holing it in "self-help" although I'm currently leaning towards "parental-help" and I'm not sure if this is a good idea - hence my questions here.
I can't really expand on how it's different from other books as I think that I have a different angle and if I leak it here, someone else might go and write it first ! It is not intended for schools, there are plenty of good, comprehensive textbooks out there, it's intended for home use.
So who should I write it for - parents or kids ? I think it would have to be written differently. Do parents have the time ?? I know they're always keen to help, but often don't know how.
Again, thanks for your interest.
