One is a simply illustrated book done beautifully with watercolors. The story focuses on feelings and bullying. It helps to teach about accepting each other's difference. And that it just takes one to voice to stand up and make everyone count. It is a playful story using colors, numbers, and various feelings. This book has a beautiful take away in being inclusive.
"One turned to the colors and said,
'If someone is mean and picks on me,
I, for One, stand up, and say, No.'
Sometimes it just takes One."
