Arithmetic is the science of numbers, and also the art of computation. This textbook presents mental and written arithmetic through simple numbers. [This book was written by the Brothers of the Christian Schools and published by De La Salle Institute.]

Correction is given to problem involving number grids presented in May, 1969, Arithmetic Teacher. (RS)

A rational presentation of the so-called long division method for extracting the square root of a number. Diagrams are used to show relationship of this technique to the binomial theorem. Presentation exposes student to many facets of mathematics in addition to the mechanics of funding square root and cube root. Geometry, algebraic statements,…

Children tend to view the equals sign as an operator symbol bereft of the rich relational properties of equality statements. It has been argued by some that this restricted view of the equals sign is due to cultural or cognitive factors. We suggest a significant factor is that rich relational meanings lack relevance within the context of…

The game presented in this article provides for students' development of the use of models, benchmarks, and equivalent forms to judge the size of fractions in a motivational and flexible way.

Effects of guided (GI) and direct instruction (DI) in solving subtraction problems for mathematically low performers in regular schools were compared. In the GI condition, self-development of solution procedures was encouraged whereas in the DI condition one prescribed strategy was to be used. Forty children (M[subscript age] = 9.3 years) were…

This study determined the effect of Cuisenaire Rods' approach on some Nigeria primary pupils' achievement in decimal fractions. Three hypotheses guided the study. A total of 200 Primary six pupils (that is, 6th grade) from randomly selected schools in Makurdi metropolis of Benue State of Nigeria served as the sample for the study. A Mathematics…

Background: Developmental dyscalculia is a heterogeneous disorder with largely dissociable performance profiles. Though our current understanding of the neurofunctional foundations of (adult) numerical cognition has increased considerably during the past two decades, there are still many unanswered questions regarding the developmental pathways of…

Reported are the results and conclusions of an arithmetic investigation made in the schools of Scotland in the spring and fall of 1966. The first problem in this investigation was to ascertain which, if either, of two unlike programs of instruction was more effective in developing skill in computation. The second was to determine the value of an…

Analysis of arithmetic problem-solving difficulties among secondary school learning disabled students (N=63) indicated students had the most difficulty with problems of the indirect type and problems that contained extraneous information. Teaching suggestions are offered. (Author/DB)

Suggestions are offered for reteaching basic arithmetic facts to older students who have not mastered them. Suggestions deal with thinking strategies and generalizations and remediation is based on students' understanding of the operation under consideration. (CL)

The author discusses some unique and non-routine ways of developing the multiplication facts. (CT)
