While shy Leo wants no part of sharing ways to be kind aloud with his new kindergarten class, that doesn't mean he isn't kind.Leo enjoys quiet activities and time with his extended family, so it's only natural that he's nervous about starting school. Luckily, Leo has the perfect teacher. Not only does she greet Leo personally and offer to help him get through his nervousness, but she also sets him up with new friends who also prefer quiet activities. Still, Leo, who wears a zipped-up jacket with the hood up, attempts to blend in and hopes Ms. Perry won't call on him to contribute ideas to the Kindness Pledge the class is working on. But Leo and his kindness are certainly not invisible to his new classmates, who specifically call out the many ways he has been kind during the day. Suddenly, Leo feels ready for this new adventure called kindergarten, and his now-unzipped jacket and bare head reflect that confidence. The digitally painted illustrations are full of bright colors and familiar school scenes. An author's note describes how to use the Kindness Pledge in classrooms, when it may be especially helpful, and reminds readers that it's also important to be kind to yourself. Leo, his family, and Ms. Perry are brown-skinned, and Leo's classmates are racially diverse.
