The observations of a fifth-grade student concerning number patterns are recorded and discussed. (SD)

The author criticizes some highly publicized psychological research on the development of number concepts, arguing that the research was poorly executed and emotively reported. (SD)

Brief descriptions of serious learning disorders which apply to mathematics are given. (DT)

The number concepts of greatest common divisor and least common multiple are related to star patterns created through line designs. (JT)

The possibilities that magazines have to offer in the teaching of mathematics with consumer-related problems are discussed. (JT)

Instructional techniques are given for the use of calculators in (1) finding prime numbers, (2) solving trigonometric equations, and (3) solving polynomial equations. (CP)

An experimental and control group of thirty-two four and five year-old children received identical quantitative tasks except for the language used. Results showed that children's difficulties with simple arithmetic tasks were not purely linguistic. The conclusion supports the suggestion that the development of language is intertwined with…

A variety of calculator activities is described for developing problem solving skills without getting involved in tedious computations. (JT)

Delay of gratification and temporal span were investigated in 58 girls, ages 4 to 9 years, by estimated story durations, delay of gratification in a direct choice money test, and reproduction of a 60-second interval. (BD)

Describes three activities to reinforce recognition and formation of numerals and letters, to make classroom activities interesting and different, and to prepare a personalized gift that encourages the student's feeling of self-worth. Activities are presented in a clip-and-save format, with each carrying an identifying number and including…

The author presents two examples of lattice multiplication followed by a computer algorithm to perform this multiplication. The algorithm is given in psuedocode but could easily be given in Pascal. (PK)

Describes activities in a mathematics class for six-year-olds. The article makes several points, including: working independently is very absorbing; investigative work is as important as algorithms; and children working in groups can achieve more than even the brightest child working alone. (PK)

The article includes a discussion of counting and counting strategies. In addition, there are eight problem sets appropriate for use with groups of different age and ability levels. Suggestions are given for finding variations of the problems. (PK)

The author advocates a return to "traditional" elementary algebra content. Several roles for algebra manipulation are identified, including making arithmetic more interesting and understandable and providing facility indispensable for both the technician and the mathematician. (PK)

Presented is a rationale for the importance of estimation. Strategies used by good estimators, and teaching strategies for computational estimation are considered. (PK)
