      Euclidean/Spherical/Hyperbolic Spaces - Henderson 
             Courses - Young | Constructor - Soda

  HYPERBOLIC SPACES - David W. Henderson; Cornell University

A book that presents a series of problems. Most of the 
chapters start intuitively and are accessible to a general 
reader with no particular mathematics background; however, 
the discussions were written for mathematics majors and 
mathematics teachers and thus assume a corresponding level 
of interest and mathematical sophistication. 

This expanded and revised edition of _Experiencing Geometry 
on Plane and Sphere_ ranges from What is Straight? through 
theorems and postulates to polyhedra, manifolds, and the 
shape of space. It includes an appendix with Euclid's 
Definitions, Postulates, and Common Notions,
and an annotated bibliography,


                    COURSES - Elaine Young
   Required math courses for majors in Elementary Education, 
       Special Education, and Early Childhood Education
                at the University of Oklahoma

- Arithmetic for Elementary Teachers
  Illustrated introductions to the concepts of real numbers, 
  operations, properties, base 5, divisibility, prime numbers,
  greatest common divisor (GCD) and least common multiple (LCM), 
  sequences, and functions.

- Data Analysis and Geometrical Systems
  Illustrated introductions, with vocabulary glossaries, to 
  concepts of probability, statistics, and geometry.
  A page of statistical graphs elaborates on the advantages and 
  disadvantages of representing data with frequency tables, 
  pictographs, line plots, pie charts, map charts, histograms, 
  bar graphs, line graphs, frequency polygons, scatterplots, 
  stem and leaf plots, and boxplots.

- Using Children's Literature in Mathematics
  A list of children's books, by mathematical category, that 
  can be used in math lessons.


                       CONSTRUCTOR - Soda


Constructor animates and edits two-dimensional models made 
out of masses and springs. The springs can be controlled 
by a wave to make pulsing muscles, and you can construct 
models that bounce, roll, walk, etc. Try some of the 
ready-made models or build your own.
