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…

Describes how students can compute and estimate, mentally and rapidly, by using appropriate number relationships. (YDS)

Discusses zeroes at the ends of decimal fractions representing measurements or real-world applications of numbers including precision, variance, and classroom applications. (YDS)

Two mnemonic acronyms can help learning-disabled children remember to complete the necessary steps for regrouping in addition and subtraction. (DB)

Described is an activity demonstrating how a scientific calculator can be used in a mathematics classroom to introduce new content while studying a conventional topic. Examples of reading and writing large numbers, and reading hidden results are provided. (YP)

This paper advocates the use of symbolic computation packages as another aid in teaching geometry. The need for such packages and their use in computerized proofs are demonstrated by a problem in high school planar geometry. (LZ)

It is shown that Bayesian algorithms are computationally simpler in frequency formats than in the probability formats used in previous research. Analysis of several thousand solutions to Bayesian problems showed that when information was presented in frequency formats, statistically naive participants derived up to 50% of inferences by Bayesian…
