Stuart Murphy creates a funny, and realistic story between a mother, son, and daughter. The story explains what a half of something is, and in this books case its half of a cookies, pizza, juice, and cupcakes. Something I learned while reading this book was Stuart was trying to convey not only the mathematical message but as well as teaching children that its polite to share, and they you have to work together. I think this would work well when introducing a group project and sharing materials, and I think this book would be best used in a 1-3rd grade classroom.
