Development of the repeating decimal expansion for rational numbers is discussed. Expressions for numbers in other bases are also presented. (SD)

Research investigating the performance of students in grades 4 through 7 on varying items involving the distributive property is reported; results, showing low performance levels, are analyzed. (DT)

Early experience with grouping objects is valuable for later understanding of and work with place value, division, and multiplication. Examples are drawn from the Developing Mathematical Processes Curriculum Project at the Wisconsin Research and Development Center for Cognitive Learning. (RS)

Illustrations of the misuse of the associative property in elementary school texts are given; the question is raised as to the appropriateness of stressing the commutative and associative properties at the elementary level. (DT)

Children enjoy playing a game based on addition module seven. The system can be applied to questions concerning the days of a week. (SD)

A multiplication algorithm based on a perfect square is described. (SD)

A case is made for a comprehensive curriculum that includes strong competencies with not only number ideas and computation, but also with other mathematical topics such as geometry, statistics, probability, and estimation. (MP)

Addition and subtraction of integers can be approached through the use of chips of two colors. (SD)

On behalf of the Editorial Panel of the "Arithmetic Teacher," the authors outline a concensus concerning the importance of computational skills in the mathematics curriculum. Ten specific points are made concerning the needs of the student, classroom practice, the nature of computational learning, and needed research. (SD)

Using a great variety of word problems drawn from many contexts can make multiplication and division rules more relevant to the student's needs. (SD)
