Read Shel Silverstein's poem "Shapes" aloud to students. As they listen, have them follow along at their desk with a set of paper shape cutouts (rectangle, square, triangle, circle, as well as a couple of other shapes not included in the poem). Afterwards, have them retell key details from the poem in order, using their cutouts to help guide them. (What fell from the sky? Who went to the hospital? Who rolled him there? etc.) Then, have them create their own shape poem or comic strip, involving any four shapes they'd like! Encourage them to choose at least one shape that wasn't in Silverstein's poem.
