Pictured is a little squishy frog. They are great for sensory play as well as muscle development associated with fine motor skills. They can be found online or in the party favor aisle of your favorite store. 
Sometimes children need a little inspiration to write a poem. Here are few poems about frogs! 

I Have a Little Frog
I have a little frog
His name is Tiny Tim,
I put him in the bathtub,
To see if he could swim,
He drank up all the water,
And gobbled up the soap!
And when he tried to talk
He had a BUBBLE in his throat!

Five Little Tadpoles 
Five little tadpoles swimming near the shore.
The first one said, “Let's swim some more.”
The second one said, “Let's rest awhile.”
The third one said, “Swimming makes me smile.”
The fourth one said, “My legs are growing long.”
The fifth one said, “I'm getting very strong.”
Five little tadpoles will soon be frogs.
They'll jump from the water and sit on logs.

  Some Children may need help starting, give them a picture to explain, or a few sentences to get them started. Most important give  them plenty of time to read! While reading they have to fill in the missing information. 

    "In the city of Ember, the sky was always dark. The only light came from great floodlamps mounted on the buildings and at the tops of poles in the middle of the larger squares. When the lights were on, they cast a yellowish glow over the streets; people walking by threw long shadows that shortened and then stretched out again." - The City of Ember, by Jeanne DuPrau

     The story has great description sparking imagination, but leaves room for the children to fill in the blanks. They fill in what the buildings look like, what the streets are made from, and what the people creating the shadows look like.
