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)

A pack of 23 number games was devised for use by all primary grade children, regardless of physical or sensory disability. The games use all or part of a pack of 100 cards. Some experiences with the games are presented, as well as some illustrations of the games. (MNS)

The origin and current meaning of numeracy are explored. The relationships among the discipline, subject, and common use of mathematics are discussed, and barriers to modification of the school mathematics curriculum are described. (MNS)

A model is proposed in which the quantification of inverse proportionality is developed beyond the initial qualitative relation. Based on a task analysis, the model was tested with 36 eleven-year-old students in a training experiment using a balance task. (MNS)

Deriving all Pythagorean triples from simple patterns within an addition table is presented, with formulas included. (MNS)

Using sweeps to find areas, applications of reflections to miniature golf, and zeroing in on zeroes are each considered in the brief articles in this department. (MNS)

Having students try to generate their own random numbers can lead to much discovery learning as one tries to create 'patternlessness' from formulas. Developing an equidistribution test and runs test, plus other ideas for generating random numbers, is discussed, with computer programs given. (MNS)

The mechanisms, images, and language needed for the development of rational-number ideas are briefly discussed. Such ideas are sophisticated and different from natural-numbers ideas. (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)

Methods of finding algebraic expressions to fit number patterns are explored. (DT)

Activities are described which make use of rectangular arrays as a means of illustrating multiplication facts and the distributive property. (DT)

A classroom game is described in which students are asked to guess the rule relating a series of three given numbers. (DT)

Measurement of distance was used as a basis for teaching first-graders the relation of unit to quantity and the ordinal and transitive nature of natural numbers. These children performed much better on measurement evaluations and almost as well on set theory evaluations as comparison children taught through set theory. (DT)

The goal was to help 7- and 8-year olds develop computational skills in addition and subtraction. Experimental groups received instruction emphasizing mathematical structure while control groups worked on drill activities. Results showed that emphasizing structure facilitated the development of number concepts, place value, and computational…

Directions are given for games in which students can practice addition, subtraction, multiplication, and division skills. Patterns for spinners to be used in the games are provided. (DT)
