When kids pull the tabs, what will they see? Differences in size and quantity. A pretty flower grows from tall to taller to tallest. Snowflakes fall down, low . . . lower . . . lowest, as they hit the ground. And a caterpillar grows long . . . longer . . . longest! Every spread (and the front cover, too) has a pull-tab, so preschoolers will enjoy mastering this important new concept.
