shared a couple of Read Write Think resources for helping students create theme poems and shape poems. Those are good resources if your classroom is 1:1. If not, you might want to take a look at the printable templates from Make Beliefs Comix.
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.
