Two units are developed that provide the student with experience in constructing auxilary lines that are often needed in formulating geometric proofs. (MP)

This booklet contains mathematics unit plans for Algebra 1, Geometry, Math for Technology, Mathematical Problem Solving, and Pre-Algebra developed by PACE (Promoting Academic Excellence In Mathematics, Science & Technology for Workers of the 21st Century). Each unit plan contains suggested timing, objectives, skills to be acquired, workplace…

Contains five lesson plans designed to help students understand the causes of violent behavior and vandalism and to give them experience in solving problems of real-life situations. Students examine the causes and implications of violence in schools and among adolescents and effect of mass media on violent behavior. (AM)

Presents an ancient method for solving quadratic equations from Jiuzhang Suanshu (Nine Chapters on the Mathematical Art). Includes several examples and exercises. (MM)

Teaching ideas related to the instruction of decimal division as the opposite of multiplication, an approach to approximating logarithms that help reveal their properties, and the simple creation of algebraic equations with radical expressions for use as exercises and test questions are presented. (MP)

After a review of the book "Passages: Predictable Crises of Adult Life," by Gail Sheehy, the author presents a lesson plan designed to help students become aware of adult developmental tasks and stresses. (MF)

An outline is given for a lesson on gases for high school students. Solutions are given; however, requests are made for alternative solutions. (SA)

The game of "Guess What" is described as a stimulating vehicle for students to consider the unifying or distinguishing features of geometric figures. Teaching suggestions as well as the gameboard are provided. (MNS)

Briefly presents research studies on efficacy of this method; discusses the teacher's role in inquiry; and provides guidelines for evaluation. A sample lesson plan on the Civil War concludes the article. (JB)

An exercise in applied mathematics that focuses on belt drives that is suitable for senior secondary pupils is presented. Some comments on classroom use and student reactions to this lesson are included. (MP)

This book is a collection of teaching strategies and activities for teachers of secondary mathematics. This volume is the product of a workshop that focused on student understanding of directed numbers. Suggested teaching methods include introducing the number concept, using a number line, number strips, monograms, bottle top addition and…

These materials are intended to provide meaningful mathematical experiences for pre-algebra students. These experiences emphasize the development of computational skills, mathematical concepts, and problem-solving techniques. This bulletin may be used as the basis for the first term of a one-year course. The complete course is divided into 12…

This document is a collection of reports presented at a programable calculator symposium held in Seattle, Washington, in April, 1980, as part of the annual meeting of the National Council of Teachers of Mathematics (NCTM). The session was designed to review whether the programable calculator has a place in the school mathematics program, in light…

This book offers 35 lesson formats for use in secondary or higher education settings and appropriate as alternatives to the usual "lecture-presentation." The formats draw on principles of collaborative and cooperative learning and concepts of group interaction and information processing. Most lessons require substantial…

These materials are intended to provide meaningful mathematical experiences for pre-algebra students. These experiences emphasize the development of computational skills, mathematical concepts, and problem-solving techniques. This bulletin may be used as the basis for the second term of a one-year course, or for the second year of a two-year…
