Titch by Pat Hutchins
Publisher: Red Fox Picture Books
Titch is little. Everything he has is little - his little pinwheel, his little tricycle. He even plays a little whistle. Peep.
Pete and Mary are big. Everything they have is bigger than Titch's, and better. Their big bikes go faster. Their big kites fly higher. And their huge instruments are much louder. BANG!
But then Titch gets a little seed. And what comes from it is a hundred times bigger then anything Pete and Mary could ever have!
There are lots of opportunities for comparing sizes of people and objects in this story, and the ending provides a lovely talking point for how sizes can change as things grow. Children might be able to suggest why everything Titch has is smaller than the things his brother and sister have, and how this might change as Titch grows.
