January 1998: Lopaka's WWW Math
Projects  Robert Garry
Garry's pages offer rich mathematics projects and science projects that
use mathematics, with links to suggested Internet resources for
background explorations. In Lopaka's notebook you'll find
links, WWW lectures and assignments, EZine articles from CCMATH, the
Problem Zone (games and puzzles on the WWW), and current activities such
as Hawai'i STTP, a CalculusPhysics enrichment program.
February 1998: Algebra I:
Graphing Linear Equations:  Tim O'Brien
A project created for a Master's Degree in mathematics. Topics covered:
Ordered Pairs; Graphing Equations 1 and 2; Horizontal Lines; Vertical
Lines; Slope; Equations and Slope; Find Equation of Line; Scatter Plots;
Parallel Lines; Perpendicular Lines; Solving a System. Also Quizzes and
Tests; Ask the Teacher (email a question); a Discussion Room, Glossary,
Index, and Message Board; a Crossword Puzzle and Word Search; an
Internet project predicting the number of people who will vote in the
year 2004; a simple scientific calculator; and a plotter that can plot
functions, differentials, and integrals, including trigonometric
functions.
March 1998: MathsNet
 Bryan Dye
A British site for mathematics, education, information technology, and
the Internet. Pages on logo, spreadsheets, and graphs, and areas for
specific educational software and articles. MathsNet also offers a
selection of mathematical
puzzles of various kinds.
April 1998: Polls:
What do the Numbers Tell Us?  Annenberg/CPB
Take part in a survey; then follow a year in a fictitious election
campaign for an inside look at the mathematics behind the polls and the
statistics affecting the political news you hear every day. This exhibit
explores wellknown statistical concepts  random sampling, margin of
error, and confidence  through activities where YOU play the pollster.
Also included is a page of pointers to other Web sites related to
statistics. The site is part of the Annenberg/CPB Projects Exhibits
Collection, and is inspired by the PBS video Against All Odds.
May 1998: Triangle Centers
 Prof. Clark Kimberling
"Aside from the centroid, the ancient Greeks also marveled at three
other triangle centers: incenter, circumcenter, and orthocenter.
Centuries passed before a fifth triangle center surfaced: the Fermat
point. During the nineteenth century, more triangle centers entered the
literature, and then the subject died for a while. Now as we near the
year 2300 AE, new triangle centers are once again popping out, often
with the help of computers..." Prof. Kimberling offers descriptions,
illustrations, and commentary on 20thcentury and Classical triangle
centers, from Schiffler and Hofstadter to Fermat and Napoleon.
June 1998: Aunty
Math  Angela Giglio Andrews
An everyotherweek math challenge for grades K3 from "Aunty Math."
Each challenge is presented in the form of a story taken from the life
of Aunty Math, her two nephews Barney and Danny, and her niece Gina.
Students with questions or suggestions can email Aunty Math directly,
and a Tips for the Current
Challenge page provides parents and teachers with suggestions for
modifying or extending each problem. Students may also submit solutions
and read what others have written from Aunty Math's Solutions page.
July 1998: The
ShowMe Center
A National Science Foundation project supporting the implementation of
standardsbased middle grades mathematics curricula. The site features a
searchable calendar of professional development opportunities; the
ShowMe Project center and satellites, with related NSFsponsored
implementation and curriculum projects; and the Mathematics Curricula
Showcase: a tool for comparing five curricula on such key features as
content goals, process goals, learning environment, and use of
technology. These projects were funded in 1992 by the NSF to develop
comprehensive standardsbased curricula: Connected Math; Math in
Context; MathScape; MathThematics; MMAP. Also related literature:
selected articles and papers on mathematics curriculum reform.
August 1998: Project Interactivate 
The Shodor Foundation
Project Interactivate is part of the Presidential Technology Initiative.
The materials it develops are designed to be adapted easily to any NCTM
Standardsbased middle school mathematics text. Middle school
lessons cover probability, statistics, functions, and fractals. Discussions
on these subjects range from the probability of simultaneous events and
introducing elementary set operations through Internet search, to
histograms vs. bar graphs and recursion in fractals. Applets that
provide computer simulations present opportunities for group work as
well as individual investigation.
September 1998: Secondary
Mathematics Assessment and Resource Database (SMARD)
This Queensland, Australia site offers an opportunity for secondary
maths teachers to share assessment tools and other resources, including
classroom activities. Much of the assessment is alternative assessment,
known as 'authentic assessment' in the United States. The searchable and
browseable database is
divided into six main sections: Junior mathematics (years 810), Senior
Mathematics (years 1112), Puzzles, Competitions, Teaching Mathematics,
and Mathematics for Leasure. In addition there are more than 220 annotated links,
organized by topic, to Web pages that support secondary mathematics.
October 1998: The
Perfect Number Journey  Heng O. K.
Math facts and exercises that address the following questions: How to
find perfect numbers? What are Mersenne numbers? How are Mersenne primes
related to perfect numbers? How to find Mersenne primes? How were the
larger perfect numbers found? Are there any odd perfect numbers? Some
properties of perfect numbers. How are perfect numbers and triangular
numbers related? Are all perfect numbers hexagonal? What is the largest
known prime? Also from the same author: The Maths Room,
offering selected sites in a variety of mathematical categories.
November 1998: The
Amazing Mathematical Object Factory (AMOF)
Part encyclopedia and part calculator, a teaching tool that generates
mathematical permutations for some combinatorial object types: subsets,
combinations, permutations, 8queens problem, pentominoes, permutations
of a multiset, partitions, Fibonacci sequences, and magic squares; with
a link to the higherlevel Combinatorial Object Server
(COS).
December 1998: Through
the Glass Wall  TERC
Looking at
how girls and boys play mathematical computer games in order to
answer such questions as: How can children learn significant mathematics
from computer games? Descriptions of over 50 games, with reviews, sample
dialogues of children playing and interacting with games, and suggested
Web links and print resources. Topics include: gender and technology,
mathematics, and play; technology in education and in the classroom;
technology and popular culture, "games for girls"; advice on choosing
software, with links to reviewers and sellers. The project's research
questions and outcomes also offer links to papers written to date, and
an essay
on the reviews onsite exploring such questions as What does it mean
to be a good computer game?
