A bar graph and table shows school-age population projections by region and state for 1980, 1990, and 2000. The Northeast and North Central regions will show a steady decline, the West will show a steady increase, and the South will decline in 1990 but increase by 2000. (TE)

The game of "Sprouts" is explained, then several theorems concerning the game are stated and proved. (DT)

This paper investigates one high school student's use of gestures in an interview context in which he worked on the problem of understanding graphical representations of motion. The goal of the investigation was to contribute a detailed analysis of the process of learning as it occurred over a short time period in order to contribute to the…

In this activity, students design and create a LEGO (plastic building blocks) structure to house and protect a temperature sensor. The structure is left in a safe spot and the temperature is regularly checked and charted. This activity uses a time frame of 45 minutes. (Author/SOE)

This book contains volume 1 of the proceedings of the 23rd annual meeting of the International Group for the Psychology of Mathematics Education (PME) held October, 2001 in Snowbird, Utah. Papers include: (1) "Opening the Dimensions of Mathematical Capability: The Development of Knowledge, Practice and Identity in Mathematics Classrooms"…

This two volume collection of proceedings contains working group reports, research reports, oral reports, poster session reports and discussion group reports presented at PME-NA 21.

This assessment sample provides information on the Missouri Assessment Program (MAP) for grade 7 science. The sample consists of seven items taken from the test booklet and scoring guides for the seven items. The items assess heat, minerals, graphing, and plant growth. (MM)

Two teachers describe ideas they have used in teaching the concept of area. The use of physical materials is emphasized. (MM)

This column contains brief notes on graphing in three dimensions; patterns in Pascal's triangle; plotting graphs by computer; and an application of the hypocycloid. (MM)

A collection of brief articles on mathematics and teaching mathematics. (FL)

Develops stochastic model of library borrowing using Negative Binomial distribution applied to circulation data obtained from Huddersfield Public Library. Evidence concerning process of popularity decay is presented and method is given by which relegation tests can be constructed to maintain optimum turnover. Eight references and statistical…

On these worksheets, students are to graph pairs of linear equations and linear combinations of these pairs, using the results to discover an algebraic technique for solving a system of epuations. They then complete, run, and modify a computer program for solving a system of linear equations. (MNS)

Discusses computer games (called intrinsic models) focusing on mathematics rather than on unrelated motivations (flashing lights or sounds). Games include "Green Globs," (equations/linear functions), "Darts"/"Torpedo" (fractions), "Escape" (graphing), and "Make-a-Monster" (equivalent fractions and…
