What’s Up Duck?  A Book of Opposites  by Tad Hills  (2008)

This a simple board book, with clear pictures that carry well for groups of 1 and 2 year olds.  The opposites are the most basic:  loud/quiet, happy/sad, up/down, etc.  And they’re demonstrated by a very appealing cast of bird characters (two ducks, a goose, and a bluebird).  Their personalities draw readers, and they visually reinforce the vocabulary that’s in the text.
