What Questions Should I Ask My Child

  • At the end of the book, all of the colors/numbers shout, “Everyone counts!” What do you think it means to count?

  • How could you help others feel like they count?

Trusted Reviews & Ratings

Book-loving mama who believes you're never too old for magical stories of talking animals and imaginary worlds.
5.5 / 7.0

First off, I love what this book teaches about bullying. It just takes one to stand up to a bully, but the more defenders there are against the bully, the better. When “One” says he doesn’t tolerate bullying, the others gain the courage to stand up, too. Second of all, I love that this book shows how empathy is important. The colors want to be nice to blue, and blue reaches out to red because he knows what it’s like to be alone. Last of all, this book introduces main colors and numbers 1-7 with fun word play. :)
