Free Verse poems have no rhyming structure and often don't have a particular rhythm or syllable patterns; like their name suggests, they are simply 'free'. Free verse, like abstract art, is where the definition of poetry becomes complicated.
Reading free verse poetry and discussing with the children why it is a poem, what about where the lines break and the use of longer or shorter lines support meaning making in the poem can support children's understanding. It is very important that children have the opportunity to practise reading these poems aloud using the punctuation and the line breaks to support their reading.
Free verse is by far the most common form that contemporary poetry is written in.
