I'm an Atwood, Piercy, Plath kinda girl myself. When teaching the kids I tend to teach Etheridge Knight near the start and that usually goes over well. Because of a common experience. And I have a collection that came with a cd of various writers. Langston Hughes is a good next step.

When I student taught "regular education" and had a bunch of suburban kids I had a bunch of sports poems that went over really well even though I, personally, found them boring.

If I have a lot of spanish speaking/bilingual kids Pablo Neruda is good for the parallel language texts and content.

My poetry is all packed away. There are more, lesser known, poets that I love and aren't coming to me by name at the moment.
