A renowned picture book creator makes learning numbers a breeze by weaving them into the familiar scenes of a young child’s world. One is me, Katie. Here I am, all by myself. But I’m not by myself for long. Katie and her baby brother, Olly, make two, which is a good thing when they want to play hide-and-seek. Like every young child, Katie has plenty of things to count, like a friend’s four kittens, six guests at a tea party, or ten people on a crowded bus. Shirley Hughes’s sure, simple language and beguiling, realistic illustrations add up to a gentle story that easily builds preschoolers’ familiarity with numbers.
