   Fermi Off-The-Wall Math League | Platonic Realms - Smith
         Golden Section and Fibonacci Numbers - Britton

          Minnesota Intermediate School District 287

  A Fermi question is posed with limited information given, 
  and requires that students ask many more questions; for 
  example, "How many water balloons would it take to fill 
  the school gymnasium?"

  Solve new open-ended problems every week, view hints, and 
  see outstanding solutions to previous problems. To submit 
  solutions online, register with an entry fee of $25 per 
  person per session. An individual, a pair or a team of four 
  may register for this Internet-based project. Session 1 is 
  already underway; Session 2 will start February 4, 2002 
  and run through March 18, 2002.

  Jill Britton, a mathematics instructor at Camosun College in 
  Victoria, British Columbia, Canada, has created two digital 
  slide shows:

  Each site includes commentary and each graphic is linked to 
  a high resolution (800 by 600 dpi) suitable for downloading 
  for your own digital show or as transparency masters. In 
  each page, there are seven animated sequences based on the
