There's a mysterious new machine in Mr. Wilson's second-grade class. Instead of grownups telling children to "make good choices" and "be kind," this special machine shows the students exactly what they can do to bring kindness to their classroom and into their own heart! But what happens when it's time to leave school? Mr. Wilson lets his class in on a secret that they have their very own Kindness Machine inside them to spread kindness wherever they go! In the end, Mr. Wilson teaches his students that they each have their own Kindness Machine within them to help make kind decisions for others and themselves.
