Available in hardcover, this four-volume narrative world history tells the story of the entire globe, from the earliest nomadic humans all the way to the Persian Gulf war at the end of the twentieth century. It now includes the Revised Edition of Volume 4. Told in an entertaining, engaging style, The Story of the World uses the stories of women and men, countries and empires, rebels and rulers, peasants and presidents, to walk young readers through a continuous, chronological account of human events. The reading level of each volume increases slightly in difficulty, growing along with the developing ability of the children following the narrative thread. Volume 1 is a read-aloud for grades 1-2, an independent read for stronger readers in grades 2-5; Volume 2 is pitched towards grades 2-6; Volume 3 (revised in 2020), towards grades 3-6; and Volume 4 (revised in 2021), tackling the difficult topics of modern wars, has a reading level of grades 4-8.
