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.

In nature there are few sharp lines.

Even if you walk exactly the same route each time - as with a sonnet - the events along the route cannot be imagined to be the same from day to day, as the poet's health, sight, his anticipations, moods, fears, thoughts cannot be the same.
A. R. Ammons

I must stress here the point that I appreciate clarity, order, meaning, structure, rationality: they are necessary to whatever provisional stability we have, and they can be the agents of gradual and successful change.
A. R. Ammons

I can't tell you where a poem comes from, what it is, or what it is for: nor can any other man. The reason I can't tell you is that the purpose of a poem is to go past telling, to be recognised by burning.
