This beautifully illustrated book invites children to look closely to find all the ways the illustrator has integrated number into the drawings. The first page is zero—an empty winter landscape—and nothing to count. The next page is 1—one tree, one bird, one house. The next page is 2—two buildings, two trucks, two children, two men, 2 trees, and the clock is at 2 o’clock. As you turn each page notice the clock tower marking the hours, the number of blocks on the side of the page, and how the seasons change. Each page also corresponds to the months 1 to 12. Children can find mathematical ideas from the very simple to the complex in this book and can look at the pictures over and over again.
