This student book is a perfect addition to a beginning "Animals" unit. The book gives a simple definition of vertebrate animals and then explains the five different types of vertebrates: mammals, birds, amphibians, fish and reptiles. The terminology used is simple enough for early grade students to understand and read. The book comes with a full color cover or black line cover that students can color if they choose. Each page gives students the opportunity to illustrate one animal that fits into each of the categories. For more Animal Unit ideas, check out my TPT store!
