Four worksheets are designed to provide practice with addition, subtraction, and multiplication of whole numbers and decimals. (JT)

Evaluation of two methods, Stimulus Manipulation and Delay Feedback Only, for teaching four mildly handicapped students (ages 9-13) to solve missing minuend problems found both methods to be effective. However, systematic differences in error rate and long-term retention were observed, favoring the Stimulus Manipulation procedure. (Author/DB)

A computer program is given (in BASIC and Logo) to present problems of this form: Given the sum and difference of two integers, which is the larger? Other teaching suggestions are included. (MNS)

Significant differences were found favoring skill-deficient second-graders (N=10) provided with repeated preteaching trials on a selected component skill of a subtraction algorithm before they worked the entire algorithm over students (N=10) who, from the beginning of training, received systematic instruction on working the entire algorithm.…

For special education teachers dealing with slow learners or learning disabled students, the paper describes teacher-made diagnostic tasks and settings for addition, subtraction, multiplication and division. Remediation techniques and strategies for common error patterns and misunderstandings are discussed for each of the major parts of the…

A collection of games and puzzles that teachers can use to replace or supplement the usual textbook subtraction examples involving large numbers is given. Most of the nine activities are self-checking. (MNS)

This package features videotapes and a study guide that are designed to help teachers revisit the operations of addition and subtraction and consider how students can develop meaningful approaches to these operations. The study guides' sessions are on addition, subtraction, the teacher's role, and goals for students and teachers. The readings in…

Article is a demonstration lesson in elementary school mathematics that concentrates on mathematical patterns. (GB)

Three game activities are detailed. Informal work with addition and subtraction on a number line and graphing concepts are achieved with two simple dice games, and the distribution of monetary tokens is used to illustrate the division algorithm. (JP)

Work by Dutch and Belgian researchers on arithmetic problems involving addition and subtraction is reviewed, especially word problems. It is an attempt to synthesize the research on the relationship between instruction in the part-whole line diagram and the solution of problems. Both logical and psychological interpretations are discussed. (MNS)

The effect of instruction in addition and subtraction concepts and skills on the processes first-grade pupils use to solve verbal problems was studied. Children represented solutions in individual interviews. Results indicated pupils shifted from a concrete direct modeling approach to a more unified conception that incorporated symbolic…
