In this rhyming counting book, the concept of numerical sets is introduced. The book opens asking “What in the world comes one by one?” It then answers, explaining that the moon, your nose and your mouth come in singles. Then the book counts upwards, each time asking the question of what comes in that set and answering it. The book ends by looking up at the stars and the infinity of them. It invites young readers to start to think about the patterns in the natural world around them.
Day has created a rhyme that makes this book an engaging mix of poetry and science. As the rhyme dances along, the book will inspire conversation and thinking of more things that come in that type of set. The book is wisely limited to a coastal area where a young boy plays, dangling his toes and fingers in the water, sets of ten.
The art is simple enough to allow this book to be both a counting book and a book about sets. Smaller children will merrily count the nine spines on the back of a fish while older children will start to think about other things in their world that match the set. The digital art is bright colored, and cheery.
An engaging math book that can be read at different levels, this rhyming science book will be enjoyed by several ages of child. Appropriate for ages 3-5.
