Describes a group activity for writing and evaluating poetry on "pi." Notes that the activity worked well in a high-school geometry class and that the students in the class had fun with it. (RS)

This article highlights many of the components of the mathematics of division that should be integral to any curriculum and instructional practice for students with disabilities. It stresses that mathematics programs must assure students will attain high levels of competency in knowing about mathematics and in doing mathematics. (Contains…

Explains how middle school mathematics topics are often taught as separate, discrete topics without a unifying thread. Discusses the importance of proportionality as a concept with the potential to untie, relate, and clarify many important, complex middle grades ideas into a cohesive theme. (YDS)

Describes a non-standardized system of measurement in the Yup'ik culture of Alaska. Explains how this traditional system can help create connections between mathematical concepts and how these concepts are used in the world outside the classroom. (Author/NB)

Discusses a method of cubic splines to determine a curve through a series of points and a second method for obtaining parametric equations for a smooth curve that passes through a sequence of points. Procedures for determining the curves and results of each of the methods are compared. (YP)

Presents some examples from geometry: area of a circle; centroid of a sector; Buffon's needle problem; and expression for pi. Describes several roles of the trigonometric function in mathematics and applications, including Fourier analysis, spectral theory, approximation theory, and numerical analysis. (YP)

Presents examples illustrating how to teach statistics in connection with mathematical concepts. Describes using percentage problems and graphing problems in the classroom. (YP)

Discusses how to use calculators in the mathematics classroom. Provides some teaching examples. (YP)

Compares the effects of a part-part-whole curriculum for teaching the concept of number in the kindergarten to the effects of the standard curriculum. Describes the curriculum and instruction used. Overall, the treatment curriculum was successful in aiding development of basic number concepts. (YP)

Discusses a strategy for clarifying students' understanding of decimals, improving their ability to read decimals, and increasing retention of decimal skills. (YP)

Describes the "Buffon's Needle" problem, which is calculating the probability that a needle will cross one of two separated lines. Calculates the probability when the length of the needle is greater than the space of the two lines. Provides an analytic solution and the results of a computer simulation. (YP)

Reviews the underpinnings of synthetic division. Shows how to quickly obtain the coefficients of the Taylor expansion of a polynomial about a point, and a partial fraction decomposition of a polynomial. (MVL)

Investigates children's cognitive structures with respect to concepts one-half, one-quarter, and one-third as these apply to continuous circular and triangular regions. Examines the effect of an intervention program with 21 children in grades three through six. (YP)

Investigates the extent to which visual considerations in calculus can be taught and be a natural part of college students' mathematical thinking. Recommends that the legitimacy of the visual approach in proofs and problem solving should be emphasized and that the visual interpretations of algebraic notions should be taught. (YP)

Discusses the use of truth tables to help students establish valid or invalid conclusions under a given set of premises. Provides several inference examples using the truth table. (YP)
