Anno's Counting House

One by one, ten children move from their old house into their new house with all their possessions.Die-cut windows reveal the interiors of the houses and the book can also be read from back to front. The first ten numbers and the principles of addition and substraction are introduced not by rote but as part of a pleasant experience. All children are natural mathematicians, Anno believes, and by independent observation they can find other, more advanced concepts in this book.
