Mathematical Modeling  Unsolved Problems  LaGrange Students
From the CONNECTED CURRICULUM PROJECT
MATHEMATICAL MODELING IN A REAL AND COMPLEX WORLD by Frank Wattenberg
http://ascc.carroll.edu/ccp/modeling/topic.htm
"Among the first customers for a new car are engineers from competing companies. They need to know what their competition is doing and how. One of the most important tools for figuring out how a competitor's product works is reverse engineering. Engineers have a general idea of the tools used by their competitors and they can use their own ideas to try to reconstruct what competing engineers have done. This course is about modeling, or reverse engineering  not just reverse engineering a car or a piece of software but reverse engineering the world in which we live  determining the how behind the what of the spread of an epidemic, the motion of the planets, the start of a war, or inflation."

UNSOLVED MATHEMATICS PROBLEMS
(1) A COLLECTION FROM STEVEN FINCH
http://www.mathsoft.com/asolve/
An eclectic group of questions and partial answers from a member of the MathSoft R&D Team. Finch is less interested in reporting the latest incremental advances on wellknown problems than in publicizing littleknown ones. With links to related sites, his page includes:
 Favorite Mathematical Constants  The Miraculous BaileyBorweinPlouffe Pi Algorithm  On a Generalized FermatWiles Equation  Ulam sAdditive Sequences  Random Binary Trees Grown via the GaltonWatson Branching Process  A Convex Maximization Problem  Zero Divisor Structure in Real Algebras  Linear Independence of Exponential Functions  SelfAvoiding Walks of a Rook on a Chessboard

(2) UNSOLVED PROBLEM OF THE WEEK ARCHIVE  MATHPRO PRESS
http://www.wwa.com/math/puzzles/unsolvedMathProblems/archive.html
Postings of some difficult yet interesting problems that mathematicians are investigating, with references to more information about the topics. Although these problems can be understood by the average person, mathematicians have been unsuccessfully working on them for many years.

STUDENT TESSELLATIONS  LAGRANGE HIGHLANDS ELEMENTARY
http://forum.swarthmore.edu/alejandre/lagrange.html
Matt Kuntz's 3rd, 4th, and 5th grade students in the Program for Accelerated Learning at LaGrange Highlands Elementary School, LaGrange, IL, join pupils of Suzanne Alejandre and others in using Suzanne's tutorials and templates to make their own tessellations.
Their imaginative, colorful work illustrates the ease with which these tutorials can make translational symmetry accessible to elementary school students. We've featured these new tessellations in the Math Forum's Student Showcase:
