Okay so in order to write a poem you need to get a idea of what your writing about that interests you.
Examples:
Summer, history, winter, etc.
Then you describe what you want the subject to be doing or describe a scene in which your subject is in.
Kids in Summer
Then you have to decide what kind of pattern you want to the poem to be laid out in, whether the words rhyme after the next line or rhyme with the next line.
Next line rhyming: Every other line rhyming:
Dog has a dish What a dog
Where he ate Fish or he loves fish
he sure is a hog
when he eats out of that dish!
Example of a poem:
Its called the Ancient Evil
The winter winds dance upon the ice-capped plains
as a ballerina dances across the stage, free and serene
the winter winds ice-cold figures danced but in vain
for just as joy flowed through their actions, an evil was left behind.
An evil that devours the ground upon the winds passing.
Frigid winter wind oblivious to the wreckage left in its wake
yet even the simple remnants; left behind is not wanting
the frozen land beholding crystals of ice upon the icy plains.
The ancient evil abhors the honest winter wind,
with it comes the scorching heat, the killer of ice, and all that is frozen
the ancient evil holds the winter dancers within its blistering grasp
and obliterates it with absolute detest.
With the ancient evil comes the gentle caresses of the sun and the reviving rain; Spring has arrived and with it draws near the hope of another year.
