Data were generally consistent with the view that preschoolers and elementary schoolers can respond to memory probes by applying arithmetical processing to running gist from recently solved problems. Discussed are two competing interpretations of the development of working memory: fuzzy-trace theory and the generic-resources hypothesis. (Author/RH)

Describes range of options and features in gradebook programs and reviews most popular and readily available software for organizing, calculating, and updating grades: Master Grades, EA Gradebook, Gradeaid, Grader, Graphic Gradebook, Classic Plus Gradekeeping System, Records, Gradecalc, Grade Master, Report Card, Electronic Gradebook for…

Activities on estimation and mental computation are presented. Patterns on a hundred chart, an amazing fact, teaching and testing tips, and other references are included. (MNS)

Sixteen Brazilian third graders aged 8-13 were given problems involving multidigit computation. School-taught algorithms were likely to be used in school-taught problems, with little carry-over to real problem situations, but resulted in more incorrect answers. (MNS)

Some limitations of computing with calculators and computers are described, with particular reference to typical computations which might be performed by senior secondary school students. Types of errors, the laws of number, and intermediate round-offs are each illustrated, with conclusions and implications. (MNS)

Research indicates that calculators can promote mathematics achievement. Some topics with which calculators can aid are briefly discussed: problem solving, number ideas, counting, basic facts, and computation with whole numbers and decimals. (MNS)

Use of compatible numbers resulting in easy mental computations is described, along with related teaching and testing tips. (MNS)

Some benefits of helping learners think in prime numbers are detailed. Reasons for the decay of this ability are described, with short division presented as one activity which should be reintroduced in schools. (MNS)

Provides instructions and worksheets for activities on: (1) sorting sets (grades K-one); (2) telling place values of two-/three-digit numbers (grades two-four); (3) recognizing multiplication/division facts (grades four-six); and (4) computing problems that contain multiples of 10, place value problems, and subtraction problems with many zeros…

Points out aspects of counting books that may impede learning, notes general and specific criteria for evaluating counting books, and offers an annotated bibliography illustrating the application of criteria. (RH)

For six weeks, pupils in grades two, three, and four used either flash cards or a microcomputer program to practice basic subtraction and division facts. Equivalent learning resulted. (MNS)

This report on mathematics education in Soviet elementary schools was prepared by a writer for the Novosti Press Agency in Moscow. It notes that mathematics is taught by subject specialists beginning in grade 4 and provides details on both curriculum and instructional practices. (MNS)

Problems based on shopping experiences are presented on two posters. Children practice estimation and computation with addition and subtraction. (MNS)

What two teachers found when they took a close look at the results of a sentence-solving test given in grades four and five is reported. Error patterns appeared less frequently after instruction but recurred on retention tests. How students can be helped is suggested. (MNS)

Because calculators and computers obviate the need to teach certain mathematical skills that machines handle more efficiently, suggests eliminating paper/pencil computation from classrooms and introducing new, relevant topics and activities. Several of these topics/activities are discussed. (JN)
