3 years and up. Take young children around the world with our Cultural Diversity Paperback Set. The books in this set use real photographs to introduce children to life in other parts of the world. Children will go to markets, see different types of homes, and much more. These books are a great way to encourage children to look beyond their immediate surroundings and become aware of the world's diversity. Also includes a teachers guide with additional activities that can be used throughout the classroom.
