Now explore four two-day Internet projects for Algebra: - Adding and Subtracting Rational Numbers The Stock Market: interpret, organize, and analyze data, and order a prospectus from a mutual fund. - Scientific and Standard Notation The Nine Planets: analyze, explore, and interpret data, and make conjectures based on given facts. - Scatter Plot, Best Fit Line, Slope, Y-Intercept, and Equation of a Line The Campaign Trail: use these graphing techniques to predict voting patterns and outcomes. - Mean and Median, Stem Leaf Diagram, and Histogram and Rounding The Indy 500: organize and interpret data to find mean and average speeds, lap times, and more. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- GATEWAY TO MATHEMATICS: ESSAYS - Dave Rusin http://www.math.niu.edu/~rusin/known-math/welcome.html A collection of roughly 1100 short articles designed to provide an introduction to the subject areas of modern mathematics, with answers to some common and not-so-common questions; to describe a few of the milestone results and topics; and to indicate some of the key resources where further information can be found. Material is arranged in a hierarchy of disciplines; you may take a tour (good for newcomers), click on a territory on the "MathMap"; choose from a list of subject headings; or search for a topic by keyword(s). General subjects range from Foundations, Combinatorics, and Number Theory and Abstract Algebra to a "Gentle Introduction to the Mathematics Subject Classification Scheme": http://www.math.niu.edu/~rusin/known-math/index/beginners.html As you browse Rusin's pages, don't miss his collection of information about the interplay between MATHEMATICS AND MUSIC - everything from the theory of chords and how it's useful in piano-tuning to "Math and Chopin's music," "Music and Birkhoff's math," and why logarithms are relevant and what you do with them. http://www.math.niu.edu/~rusin/papers/uses-math/music/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- WWW RESOURCES FOR TEACHING STATISTICS - Robin Lock http://it.stlawu.edu/~rlock/tise98/ A paper presented at Technology in Statistics Education, a 1998 conference for teachers sponsored by the Boston Chapter of the American Statistical Association. Its purpose is to direct readers to statistics instruction support sites on the World Wide Web. The paper includes on-line course materials and texts; JAVA demonstrations; electronic journals and discussion lists; "Data, Data, and More Data" (data set archives, pages of links to data sites, government and official agencies, data about the Web, and textbook data); and miscellaneous links. An Outline and an All-in-one-page version are also available: http://it.stlawu.edu/~rlock/tise98/outline.html http://it.stlawu.edu/~rlock/tise98/onepage.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- TAPPED IN - MATHEMATICS with Dave Kershaw http://www.tappedin.org/ MONDAY, MAY 11 - 4:00 PM Pacific time; 7:00 PM in the East Does having just one computer keep you from using technology in your classroom? Here's an open invitation for teachers with access to few computers: come tell us what you do, so we can do it too. The Math Forum brings its resources to TAPPED IN's professional development multi-user virtual discussion environment. All grade levels are welcome. For questions about the discussions or using TAPPED IN, contact Dave Kershaw (kersh@mathforum.org) or Judi Fusco (fusco@tappedin.sri.com). -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/students/ Internet Resources http://mathforum.org/~steve/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ ```
