Apart, blue is blue and yellow is yellow . . . but together they make green. Bees and flowers together make honey. Soap and water become foam!

With playful art and a simple, lyrical structure, this picture book is a delightful read-aloud and the perfect way to talk about all the wonderful ways that, so often, the whole is greater than the sum of its parts.
