Stock Market Project | Spatial Puzzles - Jenicek | Math & Public Policy


THE GOOD NEWS BEARS STOCK MARKET PROJECT

http://www.ncsa.uiuc.edu/edu/RSE/RSEyellow/gnb.html

This interdisciplinary project for middle school students and
teachers includes lesson plans for English, Math, and Social
Studies, stock basics lessons, Internet links, and teacher
record sheets. The teacher may be the stock broker (best
where there's a single-line connection), or the students may
be brokers (as in a networked lab environment).

The project involves an interactive stock market competition
between classmates, using real-time stock market data from
the New York Stock Exchange and NASDAQ. Objectives:

- to recognize and use terms related to market activities
- to use research tools on the Web to make informed
decisions in developing a stock portfolio
- to allow students to track and manage their own
portfolios of stocks
- to recognize the effect that economic indicators,
company management, political climate, foreign relations,
and other variables have on the stock market

Students will learn to analyze their own stock data in
relation to the fluctuating indicators.

SPATIAL RELATIONS PUZZLES - JAY JENICEK

The SOMA Cube Page

http://lonestar.texas.net/~jenicek/somacube/somacube.html

A seven piece three-dimensional puzzle made up of three or
four cubes apiece, invented by Piet Hein, the Danish writer.
The seven pieces may be arranged into billions of different
combinations.

Piet Hein's theorem states that if you take all the
irregular shapes that can be formed by combining no more
than four cubes, all the same size and joined at their faces,
these shapes can be put together to form a larger cube.

Jenicek provides instructions for building a SOMA cube,
challenging shapes to attempt (with solutions), an example
of a SOMA proof, a SOMA cube Java applet, and links to
other SOMA web sites.

The PENTOMINOS Page

http://lonestar.texas.net/~jenicek/pentomin/pentomin.html

A pentomino is a shape made by joining five squares edge to
edge to form various combinations. There are twelve possible
shapes in a set of unique pentominos, named T, U, V, W, X,
Y, Z, F, I, L, P, and N. (You might remember all the letters
from the end of the alphabet, TUVWXYZ, and the capital
letters in the word FILiPiNO.)

The first pentomino problem was written by the English puzzle
inventor Henry Ernest Dudeny in 1907; Solomon W. Golomb gave
the puzzle its name. This page features five basic games
with variations and links to other pentomino sites.

MATHEMATICS AND PUBLIC POLICY

http://forum.swarthmore.edu/social/math.publicpol.html

Links to organizations that attempt to influence public
policy where mathematics and science are concerned, from
the American Association for the Advancement of Science
(AAAS) to the Joint Policy Board for Mathematics (JPBM).

This page from the Math Forum is part of its exploration
of Key Issues for the Math Community:
