This is an entire presentation on vertebrates, invertebrates, and many of the classifications. There is a review game at the end. I think it explains how the animal kingdom works pretty well and there are lots of fun pictures. This will help the students get to know the main types of vertebrates: mammals, fish, birds, amphibians, reptiles, as well as many types of invertebrates. There are fun facts on megalodons, and dinosuars as well. There are interactive pages as well. Hope you enjoy!
