and examples. This is a great site for review before tests or when you might
need a new way of looking at a math topic.
The Amazing Mathematical
Object Factory
Canada's SchoolNet provides a colorful, useful way to describe and "play"
with discrete mathematics, which studies combinatorial objects. The object
types here are subsets, combinations, permutations, 8-Queens problem,
pentominoes, permutations of multiset, partitions, Fibonacci sequences, and
magic squares. Each object type has a description to get you started and
a section where you can generate your own example. This is a helpful way
to learn about a topic that can be difficult for many people.
Fractal
Tutorials
Fractals are things that are made up of smaller versions of themselves. This
is a ThinkQuest semi-finalist, which helps the viewer learn about fractals
with step by step tutorials on three levels of difficulty: elementary, general
audience, and advanced readers. They'll make learning fractals understandable.
There are many animations (some require plug-in software), and activities
provided to further your understanding of fractals. With RealAudio Player
4.0, the section "Just for Kids", is narrated for the viewer. Be sure to
check out the Fractal Gallery and Fractal Landscapes.
Powers of Ten
This is an amazing visual journey consisting of 42 images - 42 powers of
ten. At one end of the journey is the immensity of the known universe, some
15 billion years old and 10 to 20 billion light years across. At the other
end of the journey is a depiction of the three quarks within a proton. The
image "One Meter Square" is in the middle of the continuum, and as you decrease
to smaller powers of 10, you find pores in the skin, DNA, and a carbon nucleus.
As you increase in powers of 10 from the central image, you move from Chicago
to the Earth to the Solar System to clusters of galaxies. Note: This is a
large, graphics-intensive site.
Symmetry
and the Shape of Space
Developed by a university math professor, this site about symmetry is for
high school students with a solid understanding of advanced math. Plane,
cyclic, dihedral symmetry, mobius bands, tori, orbifolds, and paper dolls
are highlighted. These paper dolls are not as simple as the kind you may
have cut as a child! Proofs and theorems are provided for some patterns.
The
KnotPlot Site
From a Ph.D. thesis by a computer scientist at the University of British
Columbia, this site provides a collection of knots viewed from a mathematical
perspective. The images were created to visualize and manipulate mathematical
knots in three and four dimesions. In knot thoery, two embedded circles (knots)
are considered equivalent if one may be smoothly deformed into the other
without any cuts or self-intersections. This notion of equivalence may be
thought of as the heart of knot theory. Some images require downloading.

Math Teacher's
Ten Commandments
Thou shalt accept the challenge of teaching math and educate thyself in every way so that students will learn.
Thou shalt recognize that some students fear or dislike math and be compassionate and understanding when teaching.
Thou shalt convey to students that their self worth is unrelated to their math skills.
Thou shalt adapt teaching strategies to meet the different learning styles of students.
Thou shalt respect all student questions as you would have them respect yours.
Thou shalt pursue the response of "I still don't understand" through different avenues until there is understanding.
Thou shalt not ask a class "Do you understand?" Instead, thou shalt determine what each student knows and does not know, and address student problems individually.
Thou shalt identify students in need of extra help and make certain they get it.
Thou shalt actively involve students in class, assign daily homework and quiz frequently, knowing that student discipline comes from teacher discipline.
Though they may at times seem few, thou shalt count thy blessings.
AND THE MOST IMPORTANT....THOUGH SHALL LOVE THE SUPPORT OF UNDERSTANDING PARENTS WHO CAN SEE AND UNDERSTAND THE FUTURE.
