January 2004: Science News for Kids - Science Service
Science articles written for kids, with activities for kids to try on their own and ways to interact with the site. Articles, including mathematics articles, are archived by subject. The site also includes: brain teasers and Java-based games; science fiction discussions and recommendations; science fair project ideas; and discussion questions for teachers to use in their classrooms. A standalone companion to Science News Online.

February 2004: Flash Demos for Understanding Statistics - G. Donald Allen, Texas A&M University
Interactive demonstrations to help students understand statistical data analysis. Demos explore mean, variance, correlation, and the creation of histograms and pie charts. Requires the Flash 6 player. Binaries available for PC or Macintosh. See also Allen's Flash demos for understanding physics, which include a tool for drawing polygons and dynamically calculating their areas and perimeters.

March 2004: - Jennifer Jasensky
Teaching tessellations: Pictures and mathematical classifications of wallpaper and frieze patterns from Granada, Sevilla, and Almeria, Spain. The site includes helpful links and lesson plans, plus worksheet/transparency masters.

April 2004: Study of Place - TERC
Middle school students analyze satellite images, do experiments in small groups, and engage in other investigations in the course of these two-week science modules, one about the Shackleton Antarctic expedition, and the other about ocean currents. The site provides teachers with goals and standards, assessments, instructions and tips, and other support materials.

May 2004: Center for Technology and Teacher Education - Curry School of Education, University of Virginia
The Center's faculty and graduate fellows have developed classroom activities involving technolgy, designed for: graphing calculators, microscopes and probes, digital cameras (coming soon), the website, Fathom, the Geometer's Sketchpad (version 3 or 4), GPS (Global Positioning System) devices, Microsoft Excel, and MicroWorlds (Logo). The site also offers interactive projects and downloadable files, a set of guidelines for classroom technology use, conference presentations, and annotated web sites.

June 2004: Exploring Precalculus - William Mueller
How do the vocal stylings of Ella Fitzgerald relate to a misleading statement about the American economy made by President Richard Nixon in 1972? They are both examples in Mueller's lively and intuitive introduction to precalculus. Materials center on three themes: functions, rates of change, and accumulation. Showing the subject from many angles, illustrations include algebraic, graph-based, and real-world examples, and feature Mathcad or StudyWorks as calculation and visualization tools.

July 2004: Convergence - Mathematical Association of America (MAA)
An online magazine supporting the use of mathematics history as a learning and teaching tool. Convergence includes: math history articles with special pedagogical appeal; animated mathematical demonstrations associated with the articles; reviews of books, websites, videos, and teaching aids; commentaries on historical mathematical problems and their solutions; math problems from historical sources; math quotations; and a calendar of historical events. The editors encourage use of the discussion feature to share classroom experiences, thoughts, and ideas.

August 2004: Learning Math - Annenberg/CPB
Flexible, well-designed professional development courses for elementary and middle school teachers. Video materials, accessible in a variety of formats, are coordinated with print and online resources, including Flash demonstrations. Course topics are aligned to NCTM strands, and include: Patterns, Functions, and Algebra; Data Analysis, Statistics, and Probability; Geometry; Number and Operations; and Measurement. The Web Guide explains course components, technical requirements, and how to register and obtain graduate credit.

September 2004: emGames - Wright Group/McGraw-Hill
Twelve Shockwave games aligned to the Everyday Math curriculum, for elementary school students. The games offer practice in basic operations, comparing numbers, place value, factoring, and estimation. Voiceovers explain the rules and prompt students as they play.

October 2004: Mathemagica - The JASON Academy
Online teacher professional development for K-8 with web-based math tools. Individual and district-based programs help teachers to develop their teaching skills and content knowledge, and to build a supportive online community of fellow teachers.

November 2004: In Memoriam: Terrel Trotter, Jr. - May 21, 1941 - September 16, 2004
Our friend Terry, a teacher at El Salvador's Escuela Americana, joined the Problem of the Week staff in 1999. He created many Algebra Problem of the Week puzzles, and mentored thousands of students who participated in that and other PoW services. We remember him for his passionate teaching and exploration of algebra and number theory. Terry's body of work includes: The World of Trotter Math; Algebra Problem of the Week; and All the King's Digits. Read My Story, Mi Historia for an episodic account of Terry's life, in his own words.

December 2004: Numerical Analysis and Numerical Methods Project - John H. Mathews, CSU Fullerton
Extensive modules and tutorials on various numerical analysis topics, such as solving linear and nonlinear equations, interpolating and approximating polynomials, and curve fitting. Downloadable software in Matlab, Mathematica, Fortran, C, Pascal, and BASIC. Lists of Internet and print resources on a host of numerical analysis topics, intended as background research aids for Research Experience for Undergraduates (REUs). Animations illustrating various topics. Annotated list of textbooks on numerical methods. Bibliography of the author's numerical methods papers. See also the author's Complex Analysis and Differential Equations pages.
