If you drizzle salt into a pile on top of a triangular base,
the pile will develop ridge lines. What's the geometry of
those ridges? In this article, Willowcreek Middle School
(Lehi, UT) teacher Troy Jones explores the geometric concepts
within physical salt piles using triangles, quadrilaterals,
and circles in several configurations.
This page features an article (PDF format), PowerPoint
presentation, Geometer's Sketchpad file, and textbook reference
for a classroom exploration of these concepts.
Troy developed these materials as part of the Park City
Mathematics Institute, or PCMI. This year's institute is
currently under way. See more projects, papers, and
activities from PCMI here:

Games to Relax  CuttheKnot
http://www.CTKMathGamesForKids.com/
This site presents a collection of Javabased interactive games
and puzzles with mathematical contents and a few practice
exercises disguised as games.
Alexander Bogomolny, the site's author, writes, "There are a
few games whose purpose is to allow for a relaxation period
before or after taking up the mathematical challenges. One does
have to relax from time to time."
