  1. 1999 Laptop Learning Challenge (LLC) - Toshiba/NSTA
    This challenge rewarded 20 K12 educators for their innovative uses of laptop computers. The 20 selected lessons may be browsed by subject (abstracts and downloadable PDF files are provided); they have science, mathematics, and technology components and take place in the classroom, in the field, or in informal science institutions. There are five lessons in each of four categories: Elementary Level, Middle Level, High School Level, and Informal Science (grades K12). The lessons are useful for teachers planning a science or math activity, for pre-service preparation, and for in-service professional development. more>>

  2. Education Resources for Oceanography and Earth Sciences - JPL Physical Oceanography DAAC
    A list of documents, data, and software for Education from NASA, UNESCO, the U.S. Geological Survey, the Jet Propulsion Laboratory (JPL), The National Center for Atmospheric Research (NCAR), National Space Science Data Center (NSSDC), etc. more>>

  3. Fibonacci Numbers and the Golden Section - Ron Knott
    Information about the Fibonacci series, including a brief biography of Fibonacci, the numerical properties of the series, and the ways it is manifested in nature. Fibonacci numbers are closely related to the golden ratio (also known as the golden mean, golden number, golden section) and golden string. Includes: geometric applications of the golden ratio; Fibonacci puzzles; the Fibonacci rabbit binary sequence; the golden section in art, architecture, and music; using Fibonacci bases to represent integers; Fibonacci Forgeries (or "Fibonacci Fibs"); Lucas Numbers; a list of Fibonacci and Phi Formulae; references; and ways to use Fibonacci numbers to calculate the golden ratio. more>>

  4. Interdisciplinary Mathematics - Mathematics Education at the Math Forum
    The NCTM Standards make a strong case for connecting mathematics with other disciplines, the National Science Foundation (NSF) has funded many projects and curricula with strong interdisciplinary commitments, and mathematicians are more and more seeking employment in interdisciplinary areas. Web resources, including programs and sessions at conferences. more>>

  5. Journey North - Annenberg Media
    Register online (free) for a global study of wildlife migration. Read today's news, from monarch migrations to robin populations in the south; report sightings, search the site. Numerous supplemental materials are available online, and further materials may be purchased or made with instructions from the site. Includes implementation tips from teachers. more>>

  6. Learning Network Teacher Connection - Daily Lesson Plans - New York Times on the Web
    A new lesson plan each day, each based on the day's news. Math lessons explore such topics as understanding the value of numbers in the newspaper; calculating refugee camp supply costs; examining the promise and problems of an "internet time" system; interpreting opinion polls; analyzing baseball hall of fame statistics; learning about company mergers through interpreting and creating graphs; analyzing statistics and creating graphs; using maps, statistics, and written texts to recognize the H.I.V. explosion in Africa; determining criteria of greatness in the math or social studies classroom; a lesson in comparative economics; researching epidemics; and unmasking mathematical concepts in the art world. The lesson plan archive includes many other subjects including science and technology. Authors include Alison Zimbalist, The New York Times Learning Network; and Lorin Driggs, The Bank Street College of Education in New York City. more>>

  7. Magnet/Mathematics Connections: Morse High School - Suzanne Alejandre, for the Math Forum
    Morse High School is the Center for Technology and Pacific Rim Studies. The school magnet focuses on five career paths designed to provide a multifaceted, enriched magnet program: Aeronautics, Engineering, Science, Tourism and Languages. These pages provide Internet lessons to use in mathematics classes in support of the magnet specialized areas, together with general resources for Internet enrichment and suggestions for developing additional lessons. more>>

  8. Math Awareness Month (MAM) - Joint Policy Board for Mathematics (JPBM)
    Mathematics Awareness Month - formerly Math Awareness Week (MAW) - is held each April to increase public understanding of and appreciation for mathematics. Since 1991, yearly themes and activities at the local, state, and regional levels have included mathematics and the environment, manufacturing, medicine, symmetry, decision making, the Internet, imaging, biology, oceans, "math spans all dimensions," and the human genome. Online essays, print posters, and web resources elaborate on the annual theme. Coordination for Mathematics Awareness Month is provided by the Joint Policy Board for Mathematics, which includes the American Mathematical Society (AMS), the Mathematical Association of America (MAA), and the Society for Industrial and Applied Mathematics (SIAM). more>>

  9. Mathematics of Cartography - Cynthia Lanius
    A map is a set of points, lines, and areas all defined both by position with reference to a coordinate system and by non-spatial attributes. These pages discuss how maps are used, give examples of different kinds of maps, and cover map history and math topics - lines, points, areas, coordinates, etc., in particular scale, coordinate systems, and projection. Also Problems, Resources, Careers in mapmaking, Teachers' Notes, and References. more>>

  10. National Aeronautics and Space Administration (NASA)
    Strategic Enterprises: Office of Aero-Space Technology; Human Exploration and Development of Space; Earth Science; Space Science. In particular, see NASA's resources for educators and for students, formerly organized under their Spacelink project. Links to other NASA sites (Hubble Space Telescope; Science News; Space Station; Deep Space 1) and an online newsletter, today@nasa.gov. more>>
