"The Crayons' Book of Numbers" by Drew Daywalt is a book that allows a student to associate colors, numbers, and objects that they relate to. In this picture book the reader is asked to help Duncan find his box of 10 missing crayons while viewing pictures each color is often used to draw. The main idea is to find all 10 colors including: yellow, orange, green, pink, red, purple, blue, brown, black, grey. While counting, the child can see that Duncan used the crayons to color things such as a purple wizard, green crocodile, yellow sun, orange sun, brown branch, pink dragon, blue storm/ocean, red Santa and fire truck, black rainbow, and grey elephant. By bringing the characters to life, the child sees the playful nature that the crayons add to this book. Overall I thought this book was easy to read, and give it three stars because I liked the idea of the counting book but have my favorites such as "Ten Black Dots" by Donals Crews, "The Very Hungry Caterpillar" by Erie Carle, and "One" by Kathryn Otoshi. In the same sense I liked how there was a lack of color to allow the students to use their imagination to further understand which objects to associate certain colors with. If I were a teacher I would use this book for early levels of education such as 2-5 because it covers the base ten counting numbers.
