Wet Cement. A Mix of Concrete Poems. Bob Raczka. Roaring Brook Press, 2016. (3-6) Poetry, Just for Fun Concrete poems use words to illustrate the meaning of the poems. In a poem about a mouse in a maze, the words follow in a maze shape. In the Icicle poem, words drip from the top of the page. The poems are clever and will make students think. Can you figure it out? Can you write a poem like this too?
