K12.ED.MATH - a moderated list on general math teaching 
questions, archived by the Math Forum at

- reducing fractions (12 July 2000)
 "I teach 6th grade and every year my students seem to have a
  lot of difficulty with fractions, specifically, reducing or 
  recognizing that a fraction isn't reduced...  Any suggestions 
  would be greatly appreciated. - Janet Johnson

- new teacher (19 July 2000)
 "I was just wondering if any of you felt scared when you first
  started teaching. I don't think that I will have a big problem 
  with it, but I feel that I won't be able to teach all of my 
  future students everything that they need to know..." - Robin

NUMERACY, for those interested in the discussion of educational 
issues around adult mathematical literacy, archived at:

- Monty Hall (31 July 2000)
 "You are a contestant. You have the choice of three curtains.
  Behind one is the Grand Prize, the other 2 have goats..." 
  - Jason 
  Revisiting the problem, with a link to tree diagrams from
  the apstat-l thread
  Monty Hall Problem: Tree Diagram (14 May 1998)

SCI.MATH, a discussion group focused on general and advanced 
mathematics that can be read as a Usenet newsgroup or on the Web:

- This Week's Finds in Mathematical Physics (Week 155) (16 Aug 2000)
 "It's a hot summer day here in Riverside, so I just want to 
  have fun. Break out the Klein bottles and Platonic solids!" 
  - John Baez

- Mental Limit? (17 Aug 2000)
 "I'm in need of some mathematical people to enlighten me 
  with their point-of-view... Is there a mental limit of 
  how far people can go in mathematics?" - Orion

HISTORIA-MATEMATICA - a virtual forum for scholarly discussion 
of the history of mathematics in a broad sense, among 
professionals and non-professionals with a serious interest in 
the field, archived at

- Mayan numeration (2 Aug 2000)
 "What reference(s) on Mayan mathematics are currently 
  considered to be the most authoritative? In particular, is 
  there a current resource which is both accurate and 
  accessible to a non-specialist?" - Steven Johnson
