Pages for ios and text alignment

I am using pages on the iPhone. The problem is that the text that I type does not align properly, and u have to scroll to the right and the left to see the entire text of a particular sentence. I don't want it to 'wrap' around the screen. I want it to appear as a normally formatted letter would look, ie. you look at the screen and you see the entire document. I know that there has to be a way to adjust this but I cannot find it and the help menus don't seem to answer the question. Btw, this is happening when I use the blank document to begin a letter.
