Experiences with complex numbers and graphical representations of them are discussed, with a program for a microcomputer. (MNS)

A set of three worksheets is provided, along with a guide for the teacher. Using manipulative materials, students investigate the difference between the consecutive sums of the numbers along the three sides of a triangle. (MNS)

The following ideas are presented: (1) an approach to exploring some of the patterns of prime numbers as a junior high activity; and (2) an informal introduction to continuity functions that uses pictures to represent simple physical situations, with suggestions for follow-up exercises. (MP)

A sequence of seven graphing activities is suggested for developing both prenumeration and numeration concepts and skills. (MP)

Appropriate mathematical competencies for children of ages two, three, four, and five are presented. It is suggested that mathematics programs for young children be action oriented. (MP)

Reasons for poor performance on the Digit Span subtest of the Wechsler Intelligence Scale for Children-Revised were examined, using learning disabled (LD) children who performed poorly on the test, LD children who performed normally, and average children. One LD group was unable to establish mnemonic codes for familiar auditory stimuli.…

The author describes a dialogue with his three-year-old daughter about numbers. He discusses aspects of mathematics education and how his views about how students acquire mathematical knowledge have changed. (MP)

The role of mathematics education in the elementary school classroom over the next few years is reviewed. The need for extensive reform is emphasized, especially the inclusion of noncomputational number concepts. (MP)

Several types of problems designed to provide opportunities for mathematically able students to do original and analytic thinking at grades 3 and 4 while reinforcing numeration and computation skills are presented. (MP)

A method of teaching students how to recognize when zeros are necessary and when they may be omitted is presented. (MP)

The results of this study indicate no significant differences on two achievement tests and one aptitude test between calculator and non groups. Nevertheless, the investigator notes several advantages of using the calculator. (MK)

An investigation of patterns in magic triangles leads to a number of discoveries concerning the sums of sides and corners. (MP)

Activities are described in which number patterns in two-digit multiplication exercises are investigated. (DT)

This study assessed effects of response climate by examining effects of an additional testing experience on the conservation of number performance of 4- and 5-year-old lower socioeconomic status children (N=98). Results indicated significantly higher conservation of number performance scores for both males and females. (Author)

Examined role of linguistic demarcation of numerals on cognitive representations of numbers with Caucasian children, 5-7 years old. Theorized that the linguistic paradigm does not always support the idea that language affects number concepts and that children's performance is shaped by other constraints. Results suggest that the task reflects…
