This Slide and Discover series is amazing! If you are looking for some great atlases, I highly recommend this series. My favorite is the Animal Atlas. It tells you about the different biomes on earth and how they influence the type of wildlife that live there. It covers each continent with a sliding interactive color-coded map, which shows the different types of natural areas and the animals living there. This series also has a traditional World Atlas, a Dinosaur Atlas and one for the Human Body! Awesome! Recommended for ages 7+.
