Besides the actual reading in class of many poems, I would suggest you do two things: first, while teaching everything you can and keeping free of it, teach that poetry is a mode of discourse that differs from logical exposition.
I see mysteries and complications wherever I look, and I have never met a steadily logical person.
I guess I just prefer to see the dark side of things. The glass is always half empty. And cracked. And I just cut my lip on it. And chipped a tooth.
