Children Map the World: Commemorating the International Map Year, volume 4, presents 50 maps created by children ages 5 to 15 for the 2015 International Cartographic Association map design competition, held in Brazil. These various types of maps convey powerful messages of various emotions that reflect this competition's theme: -My Place in Today's World.- This edition also includes what the organizers call an -atlas- of 50 additional outstanding maps from previous competitions; these maps and images are featured in part two of the book. Children, parents, teachers, and map enthusiasts will delight in the work of these imaginative young cartographers. The children's representations of the world and life on it demonstrate their varied perspectives on the state of our planet, from optimism to pessimism, grandeur to light-heartedness, and beauty to sobering and sometimes frightening truths.
