Types of errors made by children in addition and subtraction are presented and discussed. Suggestions are given for testing, diagnosing, and prescribing for instruction. (MNS)

Recommendations for remediation of 28 distinct common error patterns in arithmetic computation are described. (SD)

A variety of student work procedures and answer patterns for whole-number computation is examined. Specific suggestions for helping students who make each type of error are offered. (MN)

This study compared the error patterns of third- and fourth-grade children on addition, subtraction, and multiplication exercises in horizontal and vertical formats. The research design used parallel eight-item tests for each operation; the only difference between items on parallel forms was the formal (horizontal or vertical) of the computational…

The study of computational errors among sixth grade students included identification and classification of errors, investigation of the effects of two feedback treatments and of classwork and homework on error patterns, and investigation of the relationships of error patterns with intelligence, mathematics achievement, attitudes toward…

Four basic types of student errors in computation are noted and described. These are: (1) mechanical, (2) careless, (3) conceptual, and (4) procedural. It is felt many teachers deal with all errors as if they were of the unhabituated procedural type, with not enough attention given to other possibilities. (MP)

The procedures used for locating documents on diagnosis and prescription in mathematics are described, and the coding system used in reporting the documents is explained. Appendices include lists of basic documents, basic sources, frequently cited authors, and relevant phrases and concepts; a partial bibliography of documents concerned with…

Advances the idea that performance errors should contribute positively to the process of learning. Argues that errors do not occur randomly and that instructional theory should not condemn errors, but seek them. (PK)
