How to turn the poem into a story: keep the four events (raven finds food → fox sees him → fox flatters him → beak opens), change the poet's lines into your own sentences, add a little description of the woods, and then invent a new ending — one where the raven is not fooled, or where the fox does not keep his prize.
This is a story about a clever fox named Reynard and Mr Raven. One day, Mr Raven found a big piece of bread in the park and flew up with it to a branch of the tallest tree in the woods. Just then Reynard the Fox came trotting by. He looked up, saw the bread, and his mouth began to water.
“My word!” said the Fox in a sweet voice. “Sir Raven, you are a handsome bird. Such feathers! If you would only sing, the birds of these woods would call you King.”
Mr Raven felt very pleased. He lifted his head and was just about to sing — when he remembered something. Only that morning, his mother had told him, “A croak is a croak, my son, however much anyone praises it.” So instead of opening his beak, the Raven quietly tucked the bread under his foot, held it tight, and croaked one short, rude “Caw!”
The Fox jumped back in surprise. “That,” said the Raven, “is my whole song. And you may have it free, since you like my voice so much.” Then he flew away with his bread, leaving Reynard standing hungry under the tree. From that day on, Mr Raven was known in the woods not as the King of singers, but as the bird who could not be flattered.
