Shape poetry is a type of poetry which describes or defines an object (or concept, function or characteristic) and is shaped as the object (concept, etc) being described.
For example, in math class students can demonstrate their knowledge of geometric shapes (even three dimensional ones!) by constructing a work of art. They can show what they know. They can type or write or stencil their words, rhyming or not, and arrange them to explain terminology. Quadrangles, cylinders, squares, oh my!
Life does indeed imitate Art. Get out the construction paper, scissors and glue and have your students start getting plenty of poetic projects "in shape."
