Activities to develop counting skills are given. (MK)

A technique is described whereby the center of an irregularly shaped object can be determined. Several activities are suggested that require the use of a piece of cardboard mounted at its center of gravity. (SA)

Attainment relative to six cognitive operations and four number and computational skills was assessed for 90 elementary students using clinical procedures. Variance associated with conservation of number, seriation, and logical classification competency accounted for a significant proportion of the variance in achievement scores. (Author/MK)

The author suggests that educators are not using enough nonprint materials or are not using them correctly. She lists inexpensive nonprint materials in the areas of reading, writing, and computation which are worth previewing. (KC)

This essay discusses the possible types of uses of calculators in the elementary school, citing several publications, articles, and research studies. (MP)

This calculator experiment for seventh-grade students on prime factorization contains objectives, difficulties, a discussion, several examples, and a worksheet. (MP)

Two units of study are given here for teaching elementary school students the use of the programable calculator. Storage registers and the program memory are considered. (MP)

Factors suggested as accounting for poor problem solving are inadequate programs for teaching problem solving, choice of operation, and the number of problems. (MP)

A method is given for computer calculation of transcendental functions. (MK)

Explores the mathematical abilities of human infants compared with various species of animals. Studies indicate that human infants enter the world capable of doing simple mathematical operations. Nonhuman animals can discriminate among sets of objects based on the number of items in each set. Further studies may pinpoint the age at which children…

This article offers specific strategies to diagnose and remediate difficulties students may have in learning multiplication facts. Analyzes strategies students use to go from a known fact to an unknown fact. The point is made that, for many students, the order of interpretation of a number fact may affect accuracy. (DB)

Describes a project approach that uses children's own stories as a source for teaching and learning mathematics while developing language and cultural awareness. (KHR)

A study examined effects of peer-assisted learning strategies (PALS) and curriculum-based measurement (CBM) on the mathematics performance of 92 secondary students with disabilities. PALS/CBM was implemented twice weekly and CBM weekly for 15 weeks. PALS/CBM students improved their computation math skills significantly more than controls, but not…

Introduces a collection of mathematics activities that use Spain and Spanish culture as the setting for activities that involve graphing, estimation, logical reasoning, geometry, measurement, and computation. These activities are designed to appeal directly to students. (KHR)

Describes the successful use of a computer algebra system (CAS) with a student as he worked on a problem involving functions far more difficult than he had previously encountered. (Author/NB)
