Scholars have increasingly argued that we need to attend to adolescents' race, ethnicity, and culture in after-school activities to ensure positive effects. Still, little is known about adolescents' perceptions of culturally responsive practices in after-school activities (i. e., the use of diverse teaching practices, cultural engagement, and…

Whereas equity issues are mainly discussed with respect to students at risk, this article focuses on mathematical potentials of under-privileged students and therefore elaborates a wide, dynamic and participatory conceptualization of (sometimes still hidden) mathematical potentials. An extended research review theoretically and empirically grounds…

This past May, the author was more dismayed than surprised to read the "New York Times" article about the scores of parents who are enrolling their three- to five-year-olds in Junior Kumon enrichment programs. As some parents interviewed for the article expressed, their motivation in doing so was either to keep their children from falling "behind…

Getting high school students to enjoy mathematics and to connect concepts to their daily lives is a challenge for many educators. The Mathematics of Skateboarding demonstrated innovative and creative ways to engage students in content and skills mapped to state requirements for high school students in Algebra and Geometry.

This paper examines how Lesson Study (Lewis, 2002) was used in an elementary mathematics methods course held at a Professional Development School and intended to support pre-service teachers to become reflective practitioners while working alongside clinical faculty. Attention is given to detailing the features of Lesson Study that situates the…

This is the fifth in a series of articles of mathematical paper-folding recreations. Presented are instructions for folding a circular disc to produce regular polygons. (JP)

This report represents a survey of some of the school mathematics contests which are conducted in the United States. The report is based on information obtained from fifty-nine national, state, regional, and local level contests. National contests are described separately. Brief accounts of certain school mathematics contests, the extent of such…

Describes the method for verifying the accuracy of the shadow-stick method of determining east-west line with the shadow of sun. Description is also included for determining South by using a watch-shadow method. (Author/PS)

An activity that offers computational practice, pattern recognition, and the formulation of generalizations is described. (JT)

Three computer programs are listed for finding binomial probabilities. Other applications and variations are discussed. (MNS)

This pamphlet is designed for use as enrichment material for able junior and senior high school students who are interested in mathematics. No more than a clear understanding of basic arithmetic is expected. Students are introduced to ideas from number theory and modern algebra by learning mathematical ways of coding and decoding secret messages.…

A set of rules is given for developing pairs of numbers which can be plotted on a graph, to provide practice not only with graphing but also with computation. (JT)

Two kinds of secret writing, codes and ciphers, are discussed. The weakness of a ciphering system mentioned in the March 1981 issue is pointed out, and an alternate method is presented. Programs written in BASIC are presented which can be used to encipher messages and help break ciphers. (MP)
