Pages 10.1 doesn't allow me to change page order

Creating a new document with photos and text I find that new blank pages are added at the top. Once created, they cannot be moved as Pages thinks all text is connected. I created separate text boxes as captions for the photos, but pages will not allow me to rearrange the page order. So I must create a document backwards, starting with the last page and adding new pages at the top. For some reason, my mind creates things in ascending order, not descending. Nothing on Apple indicates that it can be any other way since pages KNOWS all my text flows from one box to the next and IS a word processing document (which it is not), even though I did not use that feature to tie on box to the next. This makes pages largely useless. Keynote would probably work, if I wanted a horizontal presentation, but I don't, I want a vertical presentation.
