我们很多人都会觉得儿童绘本书只是简单的图画加上简单的文字，对孩子来说才会有些难度，其实，仔细看，对成人来说也有很大的挑战。每一页上教你一个数字，对应着与这个数字相同数量的图画，不仔细观看、查找，很容易漏掉其中一两个，使得找到的数量与数字不一致，所以既需要耐心，又需要细心，更加需要观察能力。

Following on the heels of a successful abecedary, Countablock features thick pages cut into the shape of each numeral, creating a peek-through guessing game around the number form itself. One acorn becomes . . . one oak tree! From snowmen to puddles and eggs to chicks, quantities are illustrated twice: both before and after their “transformations.” As children interact with the pages, they will familiarize themselves not only with the numbers 1–100 and associated quantities, but with each numeral’s physicality—angles, holes, and curves, both front and back. Die-cut numerals include 1–10, and 20–100 by tens. Illustrated by hip British design team Peskimo, this fresh take on the 1-2-3s encourages readers to manipulate numbers in a whole new way.
