According to ShadowPoetry.com, tanka is "a classic form of Japanese poetry related to the haiku with five unrhymed lines of five, seven, five, seven, and seven syllables. (5, 7, 5, 7, 7)" Here is a nice description of "American Tanka." Though I do not see it mentioned in these two websites, one of the things that originally led me to choose this form of poetry for my youngest child, was the mention of the "unexpected." He often does what I least expect!
With those explanations of Tanka in mind, I wrote the following this morning (though I have not included the "unexpected" element as well as I perhaps should have):
The road through autumn
is freckled with falling leaves
scattered by the wind.
One morning, frost gilds the earth
in silver bits of winter.
