A method of summing finite sequences by use of formal power series techniques is described. (SD)

This position paper is an extension of a presentation delivered to the National Council of Supervisors of Mathematics and the National Council of Teachers of Mathematics at their annual meetings in San Diego, 1978. Four limits in test design are discussed: focus on low-level skills, general adherence to randomness, filling in blanks, and right…

With the advent of computers and electronic calculators, the role of logarithms in the curriculum is changing. An intuitive approach to logarithms, stressing the notion of isomorphism, is discussed. (SD)

Activities suitable for use with primary school students are described. The author offers advice concerning expectations of the students, use of the vocabulary of probability, integration of activities with other classroom work, and related topics. (SD)

Activities involving estimation of the number of objects in a configuration can motivate students to consider parametric models. (SD)

Activity questions based on the prime factorization of numbers can be answered by reference to the lattice structure of factors. (SD)

Upper-level secondary students investigated square and triangular numbers and Pythagorean triples using computers. (SD)

A learning activity relating modular arithmetic to patterns of figures determined by points equally spaced around a circle is described. (SD)

As a participant in an international student exchange program, the author visited elementary schools in Hungary. Her observations of the approach to mathematics instruction in several schools are provided. (SD)
