The aim in the current study is to examine the conceptualizations of zero in arithmetic operations among students with learning disabilities (LD) and no learning disabilities (N-LD). The similarities and differences in the understandings of students with LD and N-LD of zero in arithmetical operations will be discussed. The study is a multiple case…

Mathematical knowledge involving whole number multiplication and division is integral to understanding multiplicative structures such as ratios, slope, rate of change, and proportions, which are important in subsequent mathematical learning. In this study, we investigated the effectiveness of a research-based intervention, schema-based instruction…

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)

Preskills and strategy training were shown to be effective in helping four eight- to nine-year-old learning disabled children acquire basic multiplication and division skills. (Author)

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 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'…

Presented is a paradigm for teaching basic and semibasic arithmetic facts to children with arithmetic difficulties, in which the student progresses from the use of concrete materials such as blocks, to the use of diagrams such as tally marks, to a reasoning process, to responding in an automatic manner. (DLS)

The performance of 76 students (ages 10 to 15) with learning disabilities on four tasks of arithmetic computation within each of the four basic operations was examined. Tasks varied in difficulty level and number of strokes needed to complete all items. Intercorrelations between task sets and operations were examined as was the use of…

This mathematics textbook, developed for use with slow learners and learning disabled students in secondary school, contains 17 chapters. Among the topics covered are: number words; place value; rounding whole numbers; addition, subtraction, multiplication, and division of whole numbers; reducing fractions; mixed numbers; lowest common…

Six fifth-grade students with learning and/or behavioral/emotional disabilities received peer tutoring on multiplication and division facts using 3 drill and practice conditions varying in the ratio of unknown to known facts (30:70, 50:50, and 70:30). Five of the students mastered facts at a faster rate in the 70% unknown/30% known condition. (DB)

This document contains a training manual and reading and math basic skills curricula for use in specific learning disability programs and/or with educably mentally handicapped and emotionally handicapped students. The training manual is intended to help special education teachers understand and use precision teaching. A brief history of the…
