How do baby mammals grow? Food And with a lot of help from their mothers. This book shares the life cycle story of eight different mammal babies from habitats across the globe. Readers learn essential facts about each animal's birth, nursing, weaning, hunting or foraging skills, and other techniques that they must learn from their mother (and community) before they can be "all grown up." As they page through the expansive panoramic illustrations, readers explore the vast diversity of the mammal world and learn about those things that unite all mammals. The written text foregrounds the importance of mother's milk in infancy and learning to find food as each animal matures; the lifelike visual text provides more information about each species, including their habitat, family group, and relative size. The animals in the book are drawn from each continent (plus one from the sea ) and are arranged from shortest to longest childhoods. An extensive free Teacher's Guide provides further information and hands-on activities to expand opportunities for learning. This book is designed for students ages 7-10 (grades 2-5). Content aligns with the NGSS (detailed articulation is outlined in the Teacher's Guide).
