Mercer Mayer's Little Critter spends a lot of time getting ready for his bath.  He has lots of tub toys to gather, stuffed animals to line up, bubble bath to pour, and more.  Like all of the Critter books, this one is geared for students in the lower grades.  By reading this book students learn about having fun while keeping themselves clean.  It's a great way to get students thinking about things that float and sink in the bathtub.
