Verse by Verse is an experimental AI project from Google. Verse by Verse lets you compose poems by combining lines from the works of famous poets. In other words, it's a poetry remix tool. To use it you simply visit the site and select three poets to inspire you. Then you write your own first line of a poem. Once you've written a line of your own Verse by Verse will suggest three lines from each of the three poets you originally selected. You can then include those lines in your new poem. Finished poems can be downloaded as text overlaid on an background image.
Read Write Think used to host a great, interactive template to help students create theme poems. Unfortunately, that template was Flash-based and it no longer works. That said, the page it was hosted on still offers more than a dozen poetry lesson for use in K-8 classrooms.
Make Beliefs Comix offers more than 700 writing prompt pages. All of the pages are designed to be printed and given to students to write on. Within that collection you will find a small collection of poetry pages. All the the printable poetry prompt pages include artwork designed to spark a student's imagination. Some of the artwork is in color and some is in black and white. A bonus of the black and white artwork is that you're essentially getting a coloring page and a poetry prompt in one package.
Poetry 180 is a Library of Congress project that was created when Billy Collins was the U.S. Poet Laureate. The purpose of the project is to provide high school teachers with poems for their students to read or hear throughout the school year.

I didn't look at every poem in the list, but of dozen or so that I looked at, none would take more than a few minutes to read in a classroom. Speaking of reading in class, Collins encourages teachers to read the poems aloud or have students read the poems aloud. To that end, here's his advice on how to read a poem out loud.
