NUCALC  GRAPHING CALCULATOR 2.0
http://www.nucalc.com/
Graphing Calculator 2.0 from Pacific Tech is designed to
offer a new way of looking at math, providing symbolic and
numeric methods for visualizing two and threedimensional
mathematical objects. It features a variety of 2D and 3D
graphs, coordinate systems, numeric solutions, symbolic
methods, animation, the ability to graph multiple functions,
choices of colors, and texture map surfaces.
The Web site offers a free demo to download, and a guided
tour of mathematical objects:

THINKING ABOUT CHOICE  a mathteach discussion
http://mathforum.org/epigone/mathteach/skysencrel
"Why can't teachers allow children to make at least some
choices in math as we do in other subjects?"
 Mary O'Keefe
"If... the problems at hand are such as to require
real thought, then students need work only a handful 
and the instructor should both require them to express
their thought and engage that thought himself when
grading it. In this case, choice is reasonable."
 Lou Talman
"... one thing I think that many of the experienced
teachers may be forgetting is the amount of work
involved in teaching when you are first learning how..."
 Pat Krivoshein
"What makes a magician masterful is not the choices given
the audience, rather it is the illusion of choices.
 Ron Ferguson
A discussion that touches on using keys to grade assignments,
making homework more thoughtprovoking, varying the way
students are assigned routine skills, the use of estimating,
the teacher's responsibility to the student, and the kinds
and merits of choice in the math classroom.
