DIRT+WATER=MUD

This is a story about the ups and downs of friendship and all that comes with it, including sharing, compromising, and caring. It is a book about math concepts, friendship, and imaginative play, and is told entirely in equations.

What happens when you combine dirt and water? Mud! What do you get when you take a sheet, a flowerpot, and a stick and add them together? You transform into Her Majesty, the queen!

A young girl and her dog spend the day playing in her backyard, where with her imagination – and a few helpful props – anything can happen. A cape and a strong breeze turn the treehouse into an airplane. A sheet, a stick, and a pair of well-placed cat’s ears turn the girl into a pirate! At least, until mutiny leaves her alone in her kiddie pool . . . surrounded by sharks!
