The whole is greater than the sum of its parts—and unity and connection are most important of all—in a beautifully illustrated counting book with a timely message. One can be one thing all on its own—one star, one stream, one stick, one stone. But those on their toes, those using their smarts, know one can be more than the sum of its parts. Consider the two slices of bread that make up one sandwich, or the three lines of poetry that form one haiku, or even the ten years that form one decade. From one to ten, from sandwiches to centuries, every part is necessary to the whole. In this fascinating concept book, a simple rhyming narration aimed at younger children is complemented by informational panels about subjects like the four compass points, the five acts in Shakespeare, the seven colors of a rainbow, or the nine innings in baseball. Award-winning author Susan Hood and debut children's book illustrator Linda Yan offer a mind-expanding look at early math concepts such as part/whole relationships, fractions, and addition—while underlying themes of cooperation, peace, and kindness make this beautiful volume one to be enjoyed by anyone at any age.
