A New York City public school fifth-grader brought home the following week-long math assignment:

Historians estimate that when Columbus landed on what is now the island of Hati [sic] there were 250,000 people living there. In two years this number had dropped to 125,000. What fraction of the people who had been living in Hati when Columbus arrived remained? Why do you think the Arawaks died? In 1515 there were only 50,000 Arawaks left alive. In 1550 there were 500. If the same number of people died each year, approximately how many people would have died each year? In 1550 what percentage of the original population was left alive? How do you feel about this?
