Poetry is one more way to engage students in reading and building vocabulary.
Because the poems are easy to memorize they can read an reread connecting to the vocabulary in the poem. Like music poems can have that same sing-song pattern and rhyme.
I also like this Poetry "cootie catcher".
Each poem includes a page for posting. A mini poem for each student that can be a bookmark.
An activity page with writing or drawing (you can differentiate) and a page for cutting and pasting the poem in order and then draw a picture.
