Building a series of books primarily around numbers is a bold move, but it pays off in spades here. A brief paragraph at the beginning of each chapter establishes context. Subsequent content is presented via statistics, some of which are simply written out and others of which appear in pie charts, bar graphs, or timetables.The dynamic use of statistics makes for irresistible reading. This ideal supplement for history classes will appeal to reluctant readers. Consider for hi-lo collections, too.
