Presented is an informal technique for counting the number of different-sized equilateral triangles on an isometric grid. Five activities that relate to this topic are included. (KR)

Described is a method for drawing periodic tile patterns using LOGO. Squares, triangles, hexagons, shape filling, and random tile laying are included. These activities incorporate problem solving, programing methods, and the geometry of angles and polygons. (KR)

This article describes a way in which the computer can be used by students in exploring patterns and solving problems associated with number theory. BASIC programs are described, along with classroom questions and procedures that aid in implementation. (Author/KR)

Reviewed are two microcomputer software packages which may be useful in mathematics education: "Hands-On Math Volume 3," and "MathCAD 2.5." Listed are the educational level, hardware requirements, package contents, cost, and availability. Discussed are the functions, applications, strengths and weaknesses of each package. (CW)

Reviewed are the basic principles of cooperative learning including a rationale for its use and the formation of cooperative learning groups in the classroom. Examples of the application of this teaching method to mathematics teaching are discussed. (CW)

Discusses dimensionality in Euclidean geometry. Presents methods to produce fractals using LOGO. Uses the idea of self-similarity. Included are program listings and suggested extension activities. (MVL)

Considers activities that use LOGO to slide, turn, and flip the "turtle." Uses non-LOGO tools such as cutouts, pattern blocks, and tangrams to enhance the motion work. Provides examples and programs with explanations. (MVL)

Refutes the multiculturalist's claims to current mathematics curriculum, including misinterpretation of mathematics history, promotion of racial stereotypes, and missing ethnic groups. Discusses the need for a national curriculum. (YP)

Described is a study in which seventh graders used LOGO in place of receiving geometry instruction. It was hypothesized that angle recognition estimation and construction would be higher for the LOGO group. Reports that a difference was found favoring the LOGO group. Provides a short history of the LOGO language. (MVL)

Explores a year long computer coordinated curriculum for algebra. Discusses the model student and goals of the programs. Lists the curriculum in a weekly format with the topics for each week. (MVL)

Presents an activity in which students collect and organize data from a real-world simulation of the scientific concept of half life. Students collect data using a marble sifter, analyze the data using a graphing calculator, and determine an appropriate mathematical model. Includes reproducible worksheets. (MDH)

Solves the problem of the reproduction of rabbit pairs utilizing the Fibonacci sequence. Examines modified versions of the problem, and presents a vignette of one modification based on the author's experience in using the approach with preservice middle school teachers. Extends the approach to other related problems. (MDH)

Discusses a method of teaching the multiplication of integers to eighth-grade students that utilizes videotape recordings to represent positive and negative rates. Videotapes of students walking forward and backward in the play and rewind modes illustrate that the product of two negatives is positive. (MDH)

Discusses the "confidence factor" in pupils' attitudes about mathematics and the part it plays in their learning process. The authors outline three intervention strategies, drawing on British experience, that may encourage girls to develop confidence. (GR)

Examines the potential for site-based management and shared decision making to impact the curriculum, particularly in science and mathematics teaching and learning. Information comes from studies in two school districts that had experimented with both strategies over the years. In both districts, the strategies significantly impacted curriculum…
