One teacher's approach to the development of number sense while using calculators is outlined. The relationship between number sense and calculation is discussed. Teaching strategies and two worksheets used in this approach are presented. (CW)

Presents a lesson to compute differences of positive and negative numbers using historical events of science. Describes the skills, concepts, objectives, rationale, outline, procedure, evaluation, and extensions of the lesson. Provides a list of events in the history of science. (YP)

Describes the steps for making overhead manipulative materials on base-10 blocks, colored chips, place-value charts, number lines, and grids. Suggests the materials, procedures, and uses. (YP)

Describes two studies conducted in The Netherlands that compared two modes of off-air videotape use of educational television programs on mental arithmetic for elementary students. Active use of the videotapes with interruptions for interactive teaching are compared with passive, uninterrupted viewing, and implications for the design of…

Israeli teachers (N=142) were surveyed in a study designed to identify the effects of computer-managed practice on teaching methods, factors which encouraged teachers' adoption of computers for instruction, and the effects of this type of instruction on student learning. (IAH)

Presents two practice-discovery activities to furnish computational review in a nonroutine setting. Provides a worksheet for the activities. (YP)

Discussed is the meaning of the word "of" as is found in mathematical expressions that involve fractional numbers. The conceptual rather than numerical distinction is stressed. Teaching techniques regarding difficulties with this concept are suggested. (CW)

The consistency with which students apply procedural rules for solving signed-number operations across identical items presented in different orders was examined in a study involving 161 eighth graders. Inconsistent rule application was common among students who had not mastered signed-number arithmetic operations. (TJH)

This classic reprint was first published in 1955. Fehr discusses how to determine what is taught, and makes specific comments on the roles of planning, meaning, practice, learning, and problem solving. (MNS)

An examination of the status of teaching mathematics to deaf students showed that teachers ignore the hands-on exploration of objects that promotes conceptualization of basic mathematic principles. An arithmetic teaching strategy is proposed which is activity-based and is derived from Piaget's theory of intellectual development in children.…

Interviewed 59 2nd- and 44 3rd-year elementary school students concerning their solutions to arithmetic problems commensurate with their age and ability. The results indicate that as children progress through school, they continue to use counting as an important part of their problem-solving repertoire, combining counting skills in idiosyncratic…

Three elementary students with behavioral disorders were trained to use a cognitive "cover, copy, and compare" strategy to learn division facts. Two students increased their rate of correct responding to mastery level, the third student required additional feedback and goal setting, and all three students maintained increased rates of…

Discusses three methods to teach the order of operations to middle school students: (1) asking students to fill in operations in a statement to obtain a given answer; (2) using mnemonics to remember operation order; and (3) having students discover the logic system used by their calculators. (MDH)

A study demonstrated that the problem-solving ability of 45 first grade, Hispanic, bilingual children was related to the semantic structures of word problems in a similar manner for both of the children's languages and in a manner similar to that of monolingual speakers. (Author/LB)

Examines the effects of competition and cooperation on learning through computer-assisted instruction (CAI). A questionnaire was administered to 457 Israeli fourth graders who used two CAI arithmetic systems. The characteristics of the systems are discussed, and the results of the survey are correlated to students' gender and achievement levels.…
