Here is a great poem to get children moving to:

I Can

Like a bunny I can hop.
I can spin like a top.
I can reach way up high.
And I almost touch the sky.
In a boat I row and row.
Sometimes fast and sometimes slow.
Now a bouncing jumping jack.
I pop up and then go back.
Then sway gently in the breeze.
Like the little forest trees.
Make silly faces like a clown.
And then I quietly settle down.
