Introduces addition, subtraction, multiplication, and division of fractions using area models such as rectangles and circles, or linear models such as the number line and fraction strips. (ASK)

The study investigated types of errors made by learning disabled children by analyzing written responses to multiplication and division problems. Error classifications are discussed, and possible causes are suggested. The importance of thorough investigation of errors by teachers is stressed. (Author/DB)

A teacher describes ways in which learning disabled students can learn through tactile-kinesthetic approaches devised by the teacher. Examples are given of multiplication instruction by counting on fingers, and grammar and long division instruction through movement. (CL)

Ways to use popsicle sticks as concrete models of multiplication and division of fractions are given. (MK)

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)

The multiplication and division algorithms that are taught in German schools are presented. It is suggested that these algorithms may be better than standard algorithms in terms of development of useful concepts and processes. (MK)

Discussed is the topic of least common multiple (LCM), a rationale for its importance, and suggestions for when and how to teach it. (RH)

For special education teachers dealing with slow learners or learning disabled students, the paper describes teacher-made diagnostic tasks and settings for addition, subtraction, multiplication and division. Remediation techniques and strategies for common error patterns and misunderstandings are discussed for each of the major parts of the…

Some techniques for developing the ability to multiply and divide by powers of ten with ease and understanding are presented. (Author/MK)

Six activities useful in developing the idea of prime factorization are described. Some of these activities are best done with a calculator. (MK)

Some of the problems of learning disabled students which make teaching arithmetic difficult include: symbol-object relationships, reversibility of functions, perceptual deficits, multiplication tables, division tasks, word problems, and place values. Among suggestions for teachers are presenting and setting up problems according to students'…

The article reviews the development of mathematics error analysis as a means of diagnosing students' cognitive reasoning. Errors specific to addition, subtraction, multiplication, and division are described, and suggestions for remediation are provided. (CL)

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

A new approach to teaching the division of common fractions is described. The approach is related to the multiplication operation and involves children working with concrete materials. (MK)

Discusses arithmetic during long-multiplications and long-division. Provides examples in decimal reciprocals for the numbers 1 through 20; connection with divisibility tests; repeating patterns; and a common fallacy on repeating decimals. (YP)
