Hi again

�turn to page � / go to page � / you can find information on page��  sounds correct to me and I say that

 But my doubt was about the sentence �open you books on / at page ��

I agree with Bruce, a preposition is definitely needed.

 While I was checking about it I found out that:

- �at page� is correct

- �to page� is correct

- �on page� is incorrect

I have never learned or used �at� but it doesn�t sound strange. �to� sounds really weird. I have learned and used �on� all my life. I was hoping that a native speaker would say that �at� is BrE / �to� is AmE and �on� can be used by both, but until now all that I could find is that �on� is incorret. As I have already said a friend of mine who has lived in Canada for many years told me that he says �open your books on page�� and he doesn�t consider it incorrect. In fact, all my colleagues, English teachers, at school, say "open your books on page..." and even the students� Books have that sentence. I just wanted to be sure about the right way to say it.
