A poem with two numbers

My friend Carol Ann Heckman has studied with Denise Levertov and feeds voraciously on her work.  For many years I have loved Levertov's "The Secret" and today, rereading an email from Carol Ann, I went looking for a mathy poem by this beloved poet.  I found the following -- with two numbers (and a hint of recursion):

     The Mockingbird of Mockingbirds     by Denise Levertov

     A greyish bird
     the size perhaps of two plump sparrows,
     fallen in some field,
     soon flattened, a dry
     mess of feathers--
     and no one knows
     this was a prince among his kind,
     virtuoso of virtuosos,
     lord of a thousand songs,
     debonair, elaborate in invention, fantasist,
     rival of nightingales.

This poem rests on my bookshelf in Levertov's collection, Breathing the Water (New Directions, 1987).

Statistics -- math to improve man's lot

Today's poem honors nurse and statistician Florence Nightingale (1820-1910) and is found in a fine poetry collection by Mary Alexandra Agner, The Scientific Method.

   After Math     by Mary Alexandra Agner

               Florence Nightingale, 1820-1910

   Worth one thousand words, usually,

   but thousands dead

   were inked as a colored nautilus

   with chambers counting corpses

   by disease or sword or bullet.

   Hold this shell to your ear;

   hear only your heartbeat's echo.

   Numbers never had such voice

   until Florence drew

   coxcomb wedges for the dead.

Teaching Numbers

Californian Gary Soto  writes for both children and adults and much of his work suits both groups.  Here from A Fire in My Hands (Houghton Mifflin, 2006) is "Teaching Numbers":
