I really like Grandpa Tucker's poems. They are fun to read. Most have jokes toward the end and many have to do with topics that the kids are learning about. The best part is they are free. I see that you can now purchase them in a book from amazon as well.
I like this poem. It would be fun to have your kids practice the "Best handwriting" with this poem then give it to their teacher to say thanks for all they are doing.

A Thank You Hiss
|Sammy Snake says, "No one's so dear|
As a dedicated volunteer.
The ones who come to school each day,
Who work for love and not for pay.
They do so many different tasks,
Most anything our teacher asks.
Like help us write and cut and stuff
And then in math when it gets tough!
They help us do the bulletin board,
A smile from us is their reward.
For they do know, for goodness sake,
It's hard to be a student snake.
We hand them homework every day.
They type and file our things away.
Then sort the mail for everyone
To take back home when day is done.
We're glad they're here, they're really great!
We little snakes appreciate
The ones who spend their time like this.
We hope they like our thank you hissss."
