Tana Hoban knows what fires the eyes and minds of her young admirers the world over. And with every click of her camera, she zooms in on a new discovery--like this treasure trove, a full-color lesson on quantities. Look at the stacks of brightly colored teacups, the racks of shiny new shoes, the bin full of mouth-watering candies. Where are there more? Or fewer? Or where is there less? The questions and answers depend on what (and how) you see. Like the distinctive photographs, it's all a matter of vision.
