Subject: Re: Geometry for

Thank you, both MarieLouise and Claudia (and Richard Tchen)!  Very helpful!  
was interested to read that you both suggested the Geometer Sketchpad; I was 
just reading about that this afternoon.  And you mentioned Origami and 3-D 
space -- my daughter has loved Origami for years (perhaps this has already 
benefitted her), and literally just over the weekend (!) she had asked me if 
knew anything about Geometry in "3-dimensional space" or about Geometry that 
would deal with curves -- so what you suggest sounds like a good match for a 
direction for her, at least for now.  I don't know that these would hold her 
all year, though.  Not familiar with "n-dimensional space," but that sounds 
interesting, too.  Thank you, and other suggestions continue to be welcome, 
anyone has more.  -- Karen

>>HI.  Wondering if you had any thoughts on whether it is possible to

>>extending it, say, into her areas of interest, which are Biology and
>>Biomedical research?  The problem is that she hasn't yet studied Physics,
>>Trig or Calculus?  Would it just be better for her to complete the regular
>>9th grade curriculum, and look for Geometry applications as she moves into
>>Physics, Trig and Calc.?  Thanks for any thoughts!
