Practice counting on some of the most famous sculptures in the world Masterpieces by world-famous sculptor Alexander Calder are used to teach quantity in this artful, read-aloud board book. One & Other Numbers accompanies artworks with a conversational and relatable text that encourages readers to notice and count various aspects of the sculptures. Calder's playful abstract shapes add to the richness of the visual arc, allowing readers to build personal connections with the art. Children will not only grow more familiar with numbers and quantity, but also with the artist and his work. This fourth title in Phaidon's ``First Concepts with Fine Artists`` series includes a read-aloud ``about the artist`` at the end.
