Set up a classwide or schoolwide poetry reading. Invite parents and the community to hear students read their poems. You might add dancers and musicians to this program. Set up a coffeehouse-style poetry reading in your classroom or home. Have students sign up to read their work.
Atmosphere is everything.
Don't forget the refreshments. Host a poetry slam at your school. There are so many ways to set this up. The form is being reinvented all the time. Students can sign up to read their own work, to read the poems of others, to make up poems on the spot when given a subject.
