Practice counting by using some of the most famous sculptures in the world! The book One & Other Numbers features sculptures by the great sculptor Alexander Calder. Calder's playful and often lively abstract forms are especially appealing to young readers, and the accompanying text cleverly teaches the quantities, a crucial early learning concept. Children will become familiar not only with numbers and quantities but also with the artist and his work. Alexander Calder is one of the most recognizable sculptors in the world. Known as the inventor of the mobile, Calder revolutionized sculpture by introducing motion into his works. Besides his mobiles, Calder also created static sculptures known as 'stabiles', as well as paintings, costumes, and much more. Each title in this series of required art uses masterpieces from recognized artists to teach one of the top early education concepts for infants. Each concept is playfully explored through a curated collection of beautifully reproduced artworks, while the accompanying text enriches the experience with smart, conversational comments and an 'about the artist' text. Companion books in this series feature the art of Pablo Picasso, Ellsworth Kelly, Henri Matisse, and Josef Albers.
