The title says it all. This is a book of welcome. For kids from diverse backgrounds, perhaps coming from other countries, a classroom can be a haven, a place to share. Differences can be celebrated, such as clothes, foods, talents, skin color, and we see one person in a wheelchair; but still, with all the differences, kids can play, laugh, make music and art together, and have fun together. The extra folded pages in the back are a bonus.
