 The Million $ Mission  Cynthia Lanius
 You have your choice of two payment options on your new job: 1. One cent on the first day, two cents on the second day, and double your salary every day thereafter for the thirty days; or 2. Exactly $1,000,000. (That's one million dollars!) What's the best choice? Includes pages on exponential growth and patterns, links to exponentials on the Web, questions, and teachers notes.

 Pascal's Triangle  Math Forum/USI
 A Web unit designed to support workshops given by the Math Forum for the Urban Systemic Initiative (Philadephia and San Diego). Read about the history of Pascal's triangle and learn to construct it; view illustrations of number patterns to be discovered; carry out interactive investigations in Java script or the Geometer's Sketchpad, and explore this famous triangle through lesson plans that feature questions, answers, discussion, and student worksheets.

 PlaneMath  InfoUse, in cooperation with NASA
 Materials for elementary school students about math and aeronautics, designed to stimulate and motivate students with physical disabilities in grades 47 to pursue aeronauticsrelated careers via the development and delivery of accessible math education materials on the Internet. Recognizing that math curricula for students in these grades is most often built around the manipulation of tools such as pencils, compasses, and rulers, the designers of this site have endeavored to teach the same concepts without relying on the physical acuity of the student. Activities involve finding the shortest path between two cities or how many people can board your plane, flying a herd of buffalo to the prairies, learning to fly a rescue helicopter and how planes lift, knowing when an overcast sky is really overcast, flying a kite, and planning a flight around the country. Teachers are invited to register their classes.

 Studying Polyhedra  Suzanne Alejandre
 What is a polyhedron? A definition and a Java applet to help in exploring the five regular polyhedra to find how many faces and vertices each has, and what polygons make up the faces. Also links to a page of information about buckyballs, stories written by students after studying polyhedra, other sites with information about regular polyhedra, and other sites with information about Greece and Greek mathematicians.

 Tangrams  Tom Scavo
 Tangrams, a puzzle that helps develop spatialvisualization skills, may also be used to introduce or reinforce geometric concepts such as congruence, similarity, symmetry, etc. This unit for grades 4 through 6 uses tangrams to compute the area of polygonsÊ without formulas, introducing the terms congruentÊand similar. Contents: Constructing Your Own Set of Tangrams; The Area of Tangram Pieces; More Tangram Activities. Links to other tangram resources on the Web are also provided.

 Tessellation Tutorials  Suzanne Alejandre
 A series of tutorials that teach students how to tessellate (somewhat in the style of the art of M.C. Escher) using HyperCard for black and white and/or HyperStudio for color, ClarisWorks, LogoWriter, templates, or simple straightedge and compass. The tessellation lessons include units incorporating rotations and glide reflections, a section called "Where's the Math" that elaborates on some underlying geometric principles, comments contributed by others, and samples of student work.

 Traffic Jam Activity  Suzanne Alejandre
 A classroom activity (also called Hop, Skip, Jump) aligned to the NCTM and California Standards, to be explored through large movement experience, manipulatives, and an interactive Java applet. Students then revisit the activity, look for patterns, and write the answer algebraically. The activity: there are seven stepping stones and six people. On the three lefthand stones, facing the center, stand three of the people. The other three people stand on the three righthand stones, also facing the center. The center stone is not occupied. Everyone must move so that the people originally standing on the righthand stepping stones are on the lefthand stones, and those originally standing on the lefthand stepping stones are on the righthand stones, with the center stone again unoccupied. A teacher lesson plan is provided.

 Weather Here and There  Foster, Walton, Foertsch
 An integrated weather unit that incorporates interaction with the Internet and handson collaborative problemsolving activities for students in grades four through six. Lessons integrate math, science, geography, and language arts in the process of teaching and learning about weather phenomena. Students become involved in collaborative problem solving using email as well as through joining projects offered via the Internet. The first three lessons focus on learning basic meteorological concepts about weather elements, how to take measurements using appropriate weather instruments, and recognizing basic weather trends and patterns. The last three lessons focus on studying weather maps and applying the knowledge and experience about weather to associate weather trends and patterns in the process of making accurate forecasts. The unit culminates with a weather broadcast of a twentyfour hour forecast presented by students and focusing on a network of weather stations in the United States created by the students. Includes links to Illinois Standards and a Bibliography.
