What's Older than a Giant Tortoise?

(3) K-3 This book notes that while giant tortoises are the longest-living animals on earth, they are relatively young contrasted with giant sequoias, pyramids, and the earth itself. A clear progression backward, ending with an illustrated timeline and an explanation of how we know how old things are, helps students sort out time. Undistinguished but comical illustrations assist in making a difficult concept clearer.
