This problem deck contains over 150 problems related to the module "Using Tables to Solve Problems." The problems are presented at five levels of difficulty and contain four basic types of two-dimensional tables: (1) constant sum; (2) constant differences; (3) constant quotient or ratio; and (4) constant product. (MP)

The possibility of preparing a set of word problems of a predicted level of difficulty based on six variables (for multiplication, division, recall, conversions, operations, and number of words in the problem statement) and on regression equations developed in previous work was investigated. Four problem sets were used in grades four through six,…

Examples of the presentation and solution of variations on a common projectile trajectory problem are presented. (BB)

Problems short on computation and long on logical thinking are suggested for development of logical thinking. A set of such problems is presented. (MP)

One hundred and seven students of 365,000 students given the annual High School Mathematics Examination took part in the sixth U.S.A. Mathematical Olympiad. The top eight scores are listed along with comparative Exam and Olympiad scores for the group and individual problem scores. The problems proposed on the U.S.A. Olympiad on an International…

A sequence of numbers from combinatorial theory called the Bell numbers is discussed, along with several problems and examples that demonstrate their usefulness. (MN)

Presents two exam type questions with answers relating to organic chemistry and organic photochemistry. (SL)

The article outlines a series of mathematical tasks for gifted students (aged 7-12 years), stressing the value of research and inservice education that is firmly teacher and classroom based. (Author/DB)

The focus is on how line graphs can be used to approximate solutions to rate problems and to suggest equations that offer exact algebraic solutions to the problem. Four problems requiring progressively greater graphing sophistication are presented plus four exercises. (MNS)

The goals and history of the Mathematical Olympiads for Elementary Schools are described. Teams, levels, and gender are discussed, as well as teacher training, administration, scoring, and awards. Sample problems are included. (MNS)

Presents questions and answers about various chemical topics such as the supply of fossil fuels, mercury contamination of water, and lead and nitrous oxides emissions from gasoline. (MLH)

This book helps teachers define good questions, offers tips on how to create their own good questions, and includes a wide variety of questions for use in the classroom. Each chapter of the book is organized by subject area and age group so that teachers can locate the topic their class is working on, then select probing, thought-provoking…

Describes an alternative method to algebraic procedures for solving problems involving the proportional composition of a mixture. (TS)

Results are reported from a study of the problem-solving abilities of Swedish children aged 12-13. Illustrative problems and conclusions are given to describe a method for defining and testing problem solving. (MNS)
