Augustus and His Smile by Catherine Rayner.
Augustus the tiger was sad. So he went off to find his smile. On his way, he found shiny insects, birds, mountains, fish, and gets caught in a rain storm. And finally, there in a puddle, he finds his smile. He learns that his smile is always with him as long as he takes the time to explore and find happiness wherever he is.
This book has marvelous illustrations that are a great mix of brilliant art and child-friendly subjects. I also enjoyed the way that the words on many of the pages suit the subject. They are zigzagging with the mountain tops, waving in the water, and falling with the rain. The entire book is well designed and well written.
I love a book that presents feelings as things that are under your control. It offers an empowering look at emotions. Use this with preschoolers and kindergartners for both tiger stories and for stories on feelings.
