Compare and Contrast Lesson

Is anyone teaching compare and contrast as a text structure?  I am always looking for the perfect book.  Here is a link on Amazon for the perfect one.  Duck! Rabbit!  by Amy Krause Rosenthal.  I ordered my copy today.  http://www.amazon.com/Duck-Rabbit-Amy-Krouse-Rosenthal/dp/0811868656/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1238213897&sr=8-1

Here is a link to the video of the book being read.  It is DELIGHTFUL!
