Deals with the conversion of electronic hand calculators to timing devices. This article illustrates a conversion of a rather versatile calculator by means of simple and inexpensive circuitry. (HM)

Ways of using the calculator as a vehicle for investigating one aspect of the square root concept are illustrated. (MK)

A short history of the evolution of the calendar is given. Calculations with various time periods are given. (MK)

The author argues that the idea of canonical elements provides a coherent relationship between equivalence relations, the basis of modern approaches to too many mathematical topics, and the traditional aspect of computation. Examples of equivalent relations, canonical elements, and their calculations are given. (MK)

Suggests five steps for organizing learning experiences involving computational skills for adult basic education programs: (1) meet the needs of students; (2) incorporate lessons in communication; (3) use a variety of materials; (4) begin instruction where the student's knowledge leaves off; and (5) teach by means of concrete useful examples.

Discusses the postage rate increases in recent years and notes that if the trend continues the rate will reach three dollars an ounce by the year 2017. (GA)

An example is given of a class of problems whose solutions require the use of a scientific calculator in order to plot the graphs. (MP)

Considerations of the history of similar techniques and the structure of the method itself are used to discuss this question. (MP)

A discussion is given of a method of finger reckoning in which the numbers one through ten are represented by one's fingers. (MP)

A method of multiplying using fingers is described and an explanation given. The method is then generalized to other number bases. (MP)

This paper outlines some common applications of the statistical method of linear least-squares and examines the statistical significance of the results. (BB)

Describes a second-grade classroom project to collect pennies to buy playground equipment. The unit combined practical, hands-on experiences and reflected six standards from the National Council of Teachers of Mathematics Curriculum Standards. (MKR)

Presents a problem of triangular tiles that involves counting and probability. Includes instructor guiding questions. (KHR)

Thirty students (ages 7 to 18) with moderate intellectual disabilities were interviewed individually and their counting skills and number concepts assessed. Results showed a significant difference among the three age groups on all number skills assessed, and learning patterns were similar to those of students with normal intelligence.…

Describes the role and function of the census and discusses census taking and decision making about "counting" from two perspectives: the Supreme Court decision in Wisconsin vs New York, and the Census Bureau's current plans for the year 2000. Concluding comments explore the lessons learned from the 1990 census and the effect on the 2000…
