Eric Carle tells another valuable story with stunning illustrations in The Grouchy Ladybug. We are told the story of a grouchy ladybug that challenges creatures much larger in size. Kindergarteners and 2nd graders will be delighted with this book. This book would help teach size relations, as well as social relationships and moods. I would definitely use his book as a read aloud and have students refer to pages in the book when introducing differences in size.
