Using various aspects of mathematical structure as unifying concepts is stressed. Specific examples are given based on the concept of equivalent fractions and on the addition property of equality. (LS)

Allowing students to examine different ways of performing an operation is suggested as a means of increasing their understanding. (MP)

This article focuses on the aspect of mental arithmetic that uses thinking strategies that are effective with large numbers as well as basic facts. Two activities are suggested for lack of the four operations. (MK)

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)

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)

Drill activities for addition, subtraction, multiplication, and division that are derived from the history of mathematics are suggested. (MK)

Described are activities and games incorporating a technique of "one step" which is used with children with learning difficulties. The purpose of "one step" is twofold, to minimize difficulties with typical trouble spots and to keep the step size of the instruction small. (Author/TG)

An analysis is presented of pupil responses to several items on the second National Assessment of Educational Progress (NAEP) mathematics survey which focused on the concepts and models of the fundamental operations. (MP) Aspect of National Assessment (NAEP) dealt with in this document: Results (Interpretation).

Directions for making a device that parents can use to help children practice basic skills are given. (MK)

Worksheets are included that use triangular shapes designed to provide practice for addition, subtraction, multiplication, and division of rational numbers. (MP)

Presents four innovative game-oriented activities designed to reinforce computational and place value skills involving whole and rational numbers. The games ask students to use randomly chosen numerals to formulate problems involving given operations or concepts whose responses come closest to target responses. (MDH)

Presents reviews of the four software packages "Blockers and Finders,""Decimal Squares Computer Programs: Decimal Concepts, Addition and Subtraction, Multiplication and Division, and a Data Disk,""Number Stumper," and "Object Logo, Version 1.5." The software packages include problem-solving activities and drill and practice programs. (PK)
