Duck Pond Phonics Game

I have a carnival theme in my classroom this year.  I purchased plastic ducks from Oriental Trading and taped a vowel pattern to the bottom of each duck.  You could use this game to practice word families too.  One student comes up front to select a duck and the class says the following rhyme...
__________ went out one day, picked up a duck and what did it say?
(child's name)
I just placed all of my ducks on a blue lid to a container.  The student holding the duck reads the chunk on the bottom of the duck and we write the word in the pond.  Each student has a copy of the sheet, I put the sheet inside a plastic sleeve.  We use our dry erase markers and erase after each vowel pattern.  I tell them the words we will practice spelling for the vowel pattern  that is chosen.  Here is a n example of the spelling pattern ay.
                           

Here is a copy of the sheet I use.  I would love to hear any other ideas on how to use this game to practice different skills.
