Described is a study in which three instructional approaches were applied in second grade classes. Discussed are proportional materials, nonproportional materials, nonproportional materials with pictorial models. Findings, results, and recommendations are presented. (CW)

One teacher's approach to the development of number sense while using calculators is outlined. The relationship between number sense and calculation is discussed. Teaching strategies and two worksheets used in this approach are presented. (CW)

Teaching teams, staff development for teachers, and frequent communication concerning progress are key elements of a Texas district's efforts to improve elementary mathematics instruction without the usual loneliness experienced by teachers attempting change. The most difficult task for teachers was learning to lead their peers. (MLH)

Reviewed are two computer software packages: "Algebra Concepts: Volume One," and "Data Insights." Each package is described and the strengths and weaknesses are highlighted. Costs and system requirements are listed. (CW)

The study found the on-task behavior of one of two high-achieving as well as of a low-achieving fifth graders increased when the difficulty level of mathematics problems was manipulated to insure a greater than 70 percent success rate. (DB)

Discusses the educational value of engaging mathematics students in writing a journal. Provides a table showing the relationship between writing topics and the potential benefits. (Author/YP)

Describes a simple exploratory teaching model including exploration and codification phases. Reports the findings of a small-scale action-research project to implement and evaluate it. Concludes that there was no underachievement for the exploratory approach, and a strong association between student performances for routinized mathematical…

Discusses the differences between mathematical problem solving typically used in the classroom and problem solving that is a part of everyday situations out of school. Suggests some teaching methods to align classroom instruction with the real world. Seventeen references are listed. (YP)

Discusses a way to help children retain the desire to understand mathematical ideas and to carry out routine procedures. Describes a method using computers to teach linear equations and calculus. Eight references are listed. (YP)

Discussed are the use of probability simulations in a mathematics classroom. Computer simulations using regular dice and special dice are described. Sample programs used to generate 100 rolls of a pair of dice in BASIC and Logo languages are provided. (YP)

Discusses two problem-solving activities combining the introduction of resistance from physical science with mathematical functions. Provides questions and answers related to the activities. (YP)

Presents a lesson to compute differences of positive and negative numbers using historical events of science. Describes the skills, concepts, objectives, rationale, outline, procedure, evaluation, and extensions of the lesson. Provides a list of events in the history of science. (YP)

Investigated the effect of mathematics instruction with the aid of microcomputer illustrations on the achievement of college students enrolled in an intermediate algebra course. There was a treatment effect on the comprehensive final examination. (YP)

Describes the steps for making overhead manipulative materials on base-10 blocks, colored chips, place-value charts, number lines, and grids. Suggests the materials, procedures, and uses. (YP)

Provides two examples of the "regular falsi" method using geometry and a computer program. (YP)
