Have children write a diamond-shaped poem about the wind. Explain to children
that the first line of the poem is the one-word subject of the poem. (For
example, wind.) The second line consists of two adjectives describing
the subject (cool, gusty). The third line contains three verbs telling
what the subject does (blows, sweeps, howls). The fourth line expresses,
in two words, the writer's feelings about the subject (wonderful wind).
The last line repeats the first.
