I would say a "typical text" in mathematics would be a textbook. Something that says do it this way and don't do it that way. You need to know this in order to pass such and such a test or to go to college. Of course the textbook also tells you that math is applicable in the world, but rarely do secondary schools teach kids about the beauty and art that I have come to see in, yes really, mathematics.

The first experience I had in thinking math was wonderful was a Snow College. We did use a textbook, but it was a different kind of textbook that was written with the intent of engaging art-brained students. Thus, it went about teaching in a way that was new to me. Instead of practicing arithmetic we dove deep into riddles, nature, and probability. It was in this class that I began to see math as more of an interest rather than a "have-to". Once we read about the game show were the car is behind one of three doors and donkeys are behind the other two. When our group struggled to understand how the game really worked, our teacher would give us a hint on how to look at the problem so we could proceed.

In 11th grade, we were mostly left to fend for ourselves in learning Calculus. The teacher was there and she tried to teach. I must not have been ready for calculus. I remember sitting with a group and straining to understand the passages in the textbook. When someone would finally get an inkling of what was expected, they would let the rest of us in on it and we would attempt the homework. It was not fun, it was mostly just stress. 

I want to choose texts that are interesting for students. I do realize thought that I will have to front-load and fill the room with oxygen (prepare the students to enjoy the reading) before students read. It will also be vital to provide scaffolding for students during reading and some kind of solidification afterwards.
