Master Math Skills with World Population Problems

Over the summer, students often forget some of their math skills. One way to keep up is to practice by solving the following problems.

     Which continent will add the most people in the next 88 years?______________

     Which continent will have the biggest population decline in the next 88 years?___________

     The world's 10.5 billion population projection in 2100 comes from the United Nations. The World Almanac provides the latest 2012 figure of 7 billion people in the world and includes the Caribbean in Latin America's population.

     By how much will the population increase or decrease between 2012 and 2100 on the following continents?

Asia

      4,710,000,000 (2100)
   -  4,220,000,000 (2012)

Africa

      4,180,000,000 (2100)
   -  1,070,000,000 (2012)

Europe

        740,000,000 (2012)
    -   639,000,000 (2100)

North America

        513,000,000 (2100)
    -   348,000,000 (2012)

South America

        596,000,000 (2012)
    -   467,000,000 (2100)

A challenging game requires players to arrange from highest to lowest populations a mixed up list of countries or major world cities, such as:

Greenland                      (49,356)
Egypt                             (137,872522)
