Beede, Rudy B. – Arithmetic Teacher, 1978
Directions are given for preparing a puzzle that may be used to provide practice in computation. (MP)
Descriptors: Addition, Computation, Elementary Education, Elementary School Mathematics
Peer reviewed Peer reviewed
Spitler, Gail – Arithmetic Teacher, 1979
Allowing students to examine different ways of performing an operation is suggested as a means of increasing their understanding. (MP)
Descriptors: Addition, Algorithms, Computation, Concept Formation
Peer reviewed Peer reviewed
Liedtke, Werner – Arithmetic Teacher, 1982
Several ideas for questions and settings for interviews are presented. It is noted that although subtraction is used as an example in each case, most of the material can be easily adapted to the other basic operations. Many problems are noted with standard diagnostic tests and use of them is discouraged. (MP)

Ewbank, William A.; Ginther, John L. – Arithmetic Teacher, 1984
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)
Descriptors: Algorithms, Computation, Drills (Practice), Educational Games

Ferguson, Audrey – Arithmetic Teacher, 1981
A finger method for subtraction that has proved successful with many young subtraction-troubled mathematics students is presented. (MP)

Scheuer, Donald W., Jr.; Williams, David E. – Arithmetic Teacher, 1979
Masters to be removed and copied are given. The worksheets are designed to reinforce computational skills and the concepts of largest or smallest numbers, as well as to provide practice is using a straightedge. (MK)

Thompson, Charles S.; Hendrickson, A. Dean – Arithmetic Teacher, 1986
Specific instruction in different contexts provide needed background for solving addition and subtraction problems. The categories of problems and relative difficulties are presented, followed by an explanation of a successful instructional sequence. (MNS)

Krulik, Stephen – Arithmetic Teacher, 1980
Drill activities for addition, subtraction, multiplication, and division that are derived from the history of mathematics are suggested. (MK)

And Others; Zakariya, Norma – Arithmetic Teacher, 1980
An experimental program using the calculator in third, fourth, and fifth grades is described. Three example lessons are included, on (1) subtraction with regrouping, (2) estimation, and (3) number theory: Quadratics. (MK)

Shaw, Jean M. – Arithmetic Teacher, 1984
Problems based on shopping experiences are presented on two posters. Children practice estimation and computation with addition and subtraction. (MNS)

Musser, Gary L. – Arithmetic Teacher, 1982
Two mental algorithms, one for addition and one for subtraction, are described. It is felt such algorithms should be taught explicitly. The usual process taught for paper and pencil is seen to inhibit mental arithmetic, and a need to include mental algorithms in the regular mathematics curriculum is promoted. (MP)

Madell, Rob – Arithmetic Teacher, 1985
The author argues that children not only can but should create their own computational algorithms and that the teacher's role is "merely" to help. How children in grades K-3 add and subtract is the focus of this article. Grouping, directionality, and exchange are highlighted. (MNS)

Lappen, Glenda, Ed. – Arithmetic Teacher, 1988
Describes a finger pattern method for teaching subtraction. It is suggested that the method has several advantages over the usual methods children adopt. (PK)

Swart, William L. – Arithmetic Teacher, 1985
Findings from a study with first-grade children on addition and subtraction help make a case for a conceptual rather than a mechanized approach to the operations. How base ten blocks were used in the program is illustrated. (MNS)
Descriptors: Addition, Computation, Decimal Fractions, Educational Research

Beard, Earl M. L.; Polis, A. Richard – Arithmetic Teacher, 1981
The subtraction ideas presented are designed for elementary and junior high school children, yet are felt to be flexible enough to offer some challenge for high school students, particularly in algebra. (MP)
