Patterns resulting from polygonal numbers are explored, with examples of triangular, square, pentagonal, rectangular, and other numbers. Tables and formulas to be developed are included. (MNS)

Activities focus on the use of computers as an instructional tool. Three worksheets provide experiences with: perimeter and areas of squares; area of parallelograms and triangles; and properties of triangles. A Logo computer program is included. (MNS)

Field tests were conducted to evaluate theory-based computer-video instructional modules designed to teach or review concepts and operations for factors, prime numbers, and fractions. (MNS)

A useful approach for developing insights and discovering patterns is to examine numbers in relation to the number of their divisors. A teaching procedure for this approach is presented, with questions, answers, and homework suggestions. (MNS)

Three worksheets are given that use calculators to free students from computational restrictions and allow them to focus on the recognition of patterns and the application of numeration concepts in the development of their estimation skills. (MNS)

Outdoor mathematics is the subject of four worksheets. The activities concern pacing to determine perimeter, estimating a kilometer, area of an irregular figure, and estimating the height of a tree. (MNS)

Discusses procedures used throughout history to solve fractional and decimal divisor problems. Early rules and definitions, approaches in mathematics and methods books, "new math" approaches, research findings, and recent textbook procedures are included. Concludes by presenting nine recommendations for teaching the operation. (DH)

Use of calculators for teaching percent to first-year general mathematics students is explained by addressing such areas as sequence of lessons, teaching/learning problems, calculator errors, and recommended instructional strategies. Teaching concepts independent of calculator usage, not using special percentage keys, and initiating estimation as…

Describes: (1) a computation-oriented problem with procedures and some questions that might be asked of students; (2) four ways to help students develop positive problem-solving attitudes; (3) a strategy game; (4) a multiplication problem; and (5) several questions that will help students develop problem-solving skills. (JN)

Presents activities that have been used successfully in leading students from concrete experiences through pictorial and symbolic representations of important numeration concepts and patterns, including place value, multiples, and rounding. Each activity includes concept or skill fostered, list of materials needed, recommended grade level, and…

Presents an activity, suitable for students in grades 6-12, on generating random numbers. Objectives, equipment needed, list of prerequisite experiences, instructional strategies, and ready-to-copy student worksheets are included. (JN)

Teaching is characterized as a complex cognitive skill amenable to analysis in a manner similar to other skills described by cognitive psychology. A formal model of the process of instruction in elementary mathematics is presented and examined in light of empirical data from both expert and novice teachers. (Author/LMO)

Describes a full-year course called Applied Mathematics. The course covers topics in two general categories, namely, personal money management and job-related mathematics. General instructional strategies used and a sample student project (on budgets) are included. (JN)

This section includes brief articles on holding a 'metric review show,' the 'normal' approach to graphing, graphing polynomials by using the powers of the factors, and some sum derivations. (MNS)

The probability of winning the contest was analyzed, with the mathematical solution and a computer simulation given. A flowchart and computer program are both included. (MNS)
