The Prehistoric series (5 titles) surveys early human history through the tools or technologies that defined those civilizations. Here, iron is shown to have spearheaded an era of war waged with superior weapons, agricultural advancement (thanks largely to improved plows), wonderous architecture, developments, and a shift from bartering to using money. As is standard for this imprint, 12 topics are presented in individual double-page spreads containing inviting illustrations re, primarily photos of art, artifacts, and architecture th fact-bubble captions, accessible text, related statistics, and an additional box with a factoid or critical thinking question. The highly visual design and fast-fact format make this a reliable pick for reluctant or struggling readers, not least because it makes what could be a dry history lesson an engaging glimpse into the past.
