The Ladder of Abstraction -- by Bret Victor
Victor's idea of a ladder of abstraction is compelling. His presentation of mathematic as a succession of abstractions layered upon one another is beautiful. I suspect the idea of hierarchies of abstraction is a fertile field for exploring how grammar, logic, and rhetoric fit into the mathematics classroom.

Dan Meyer's TED talk video is interesting. He astutely identifies a deep malaise in much math curriculum (i.e. it's all grammar level material), and talks through how to pose students questions that incorporate rhetoric as well.
