THE PRECALCULUS PAGE
http://www.teleport.com/~gmhill/
Lesson plans and staff development activities with a
problem-solving approach. Materials focus on logarithms,
the binomial theorem, and the law of sines:
http://www.teleport.com/~gmhill/materials.html
Problems (without answers) on algebra, exponential and
logarithmic functions, other functions, geometry, and
sums, sequences, and series are available:
http://www.teleport.com/~gmhill/listserv.html
The site also offers pages of useful links for teachers,
and lesson plans with activity overviews from 1998 summer
workshops at Portland and Eugene, Oregon:

GALLERY OF INTERACTIVE ON-LINE GEOMETRY
The Geometry Center
http://www.geom.umn.edu/apps/
Twelve interactive online geometry programs:
- WebPisces: compute implicitly defined curves in the
plane
- Build a Rainbow: examine a mathematical model of
light passing through a water droplet
- QuasiTiler: generate Penrose tilings or design your
own nonperiodic tilings of the plane
- Kali and Kali-Jot: use an interactive editor to
learn about symmetric patterns of the plane
- Cyberview-X: define your own 3D objects with this
interactive 3D viewer
- Projective Conics: Pascal's theorem in terms of
projective geometry: specify points on a conic and
see how the theorem applies to them
- Orbifold Pinball: explore the effects of negatively
curved space
- Teichmuller Navigator: explore the space of all
different angle geometries on a genus two surface
- Integrator: experiment with numerical integration
of data sets
- Unifweb: discover and visualize families of Riemann
surfaces
- Lafite: work with any discrete symmetry group of
the hyperbolic plane

JUST FOR FUN: VOTE!
To show students the impact of using the Internet to collect
data, even if only a simple opinion, John Euchler asks you
to visit a page from his 7th grade class at Saint Stanislaus
Kostka School and vote on your favorite mnemonic device for
remembering the digits in the number pi:
