  I-MATH is an online professional development course for 
  teachers that was offered during the 2000 - 2001 school year. 
  The goal of the course, which may be offered again next year, 
  is to assist teachers in integrating technology and the 
  NCTM Standards into their teaching. I-MATH was created by 
  Cathi Sanders, of the Punahou School, in Honolulu, Hawaii.
