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, E-Zine articles from CCMATH, the Problem Zone (games and puzzles on the WWW), and current activities such as Hawai'i STTP, a Calculus-Physics 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 well-known 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 20th-century and Classical triangle centers, from Schiffler and Hofstadter to Fermat and Napoleon.

June 1998: Aunty Math - Angela Giglio Andrews
An every-other-week math challenge for grades K-3 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 e-mail 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 Show-Me Center
A National Science Foundation project supporting the implementation of standards-based middle grades mathematics curricula. The site features a searchable calendar of professional development opportunities; the Show-Me Project center and satellites, with related NSF-sponsored 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 standards-based 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 Standards-based 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 8-10), Senior Mathematics (years 11-12), 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, 8-queens problem, pentominoes, permutations of a multiset, partitions, Fibonacci sequences, and magic squares; with a link to the higher-level 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?
