It took 800 students and a big chunk of a ball field for Wasatch Junior High School to create its own map of North America Monday. The human map was the idea of social studies teacher Joe Spendlove, who thought it an impressive way to teach something about the part of the world where Utahns live. The project began weeks ago with Spendlove's gifted and talented students, who made maps and went to every homeroom group in the school to solicit help with the human map. They gave mini lessons on North American geography, so when it came time to get out on the field, Florida wasn't where Alaska ought to be. It took about 15 minutes for the classes to find their pre-assigned spots on the outline that had been created on the field. Principal Daryl Thomas had a starring role in the event. His job was to stand - more or less - where Salt Lake City is located.
