Discusses the use of grocery store advertisements to make story problems more relevant. Students made up problems and presented them to the class. (MKR)

Described is a way that elemental mathematics can be applied to explain an astronomical phenomenon. The fact that the extreme of sunrise and sunset do not occur on the shortest or longest days of the year is analyzed using graphs and elementary calculus. (KR)

The importance of integrated science and mathematics at the elementary/middle school levels is discussed. The history of the movement, the rationale, associated research questions, problems with integrated instruction are presented. A description of commercial resources, professional organizations, projects, printed resource materials, and…

Proposes sharing mathematics-related newspaper stories as a classroom method to illustrate the importance and relevance of mathematics in the students' lives. Provides examples of appropriate stories and ways they can be used in the classroom. (18 references) (MDH)

Argues that the dichotomy between domain-specific and general theories of cognitive development addressed in the "Merrill-Palmer Quarterly" special issue is unproductive. Suggests that polarities of generality and specificity exist in creative tension as seen through developmental processes. (Author/BB)

Presented is a set of mathematics problems associated with the characteristics, production, and consumption of chicken eggs. Student assignment sheets are included. (CW)

Teaching methods which can be used to teach statistics at the primary, intermediate, and middle grades are described. Teaching data analysis and problem solving in this context are discussed. (CW)

Emphasizes a real-world-problem situation using sine law and cosine law. Angles of elevation from two tracking stations located in the plane of the equator determine height of a satellite. Calculators or computers can be used. (LDR)

Describes the benchmark and decomposition-recomposition estimation strategies and presents five techniques to develop students' estimation ability. Suggests situations involving quantities of candy and popcorn in which the teacher can model those strategies for the students. (MDH)

Virtually every public issue depends on data, projections, inferences, and systemic thinking. Besides basic mathematics skills, numeracy (quantitative literacy) encompasses estimating tolerances and errors, constructing complex computer simulations, using flowcharts, drawing inferences, and calculating in three dimensions. The narrow…

Describes an action research project conducted in eighth-grade algebra and prealgebra classes. Suggests ways in which students can use their creativity to progress from a simple solution method to a method that produces a generalization and a formula. (AIM)

Discusses mathematical thinking and problems posed by seventh- grade students as part of a unit on the study of algebraic ideas. The unit involves showing how variables cause changes and also incorporates the solving of systems of equations by constructing line-graph drawings and combination charts. (AIM)

Presents a mathematics activity to model the exponential growth of the common cold, AIDS, or any other communicable disease. Underscores the effect that a friend's or partner's previous behavior may have on a current relationship and on society at large. (ASK)

Three studies examined strategy flexibility in mathematical problem solving among high school students on Scholastic Assessment Test-Mathematics problems and among college students on Graduate Record Examination-Quantitative items. Results suggested that strategy flexibility was a source of gender differences in mathematics ability as assessed by…

The following article gives a brief account of some empirical research done in the 1980s in the UK by the present author with his colleague, Ibrahim Abdel-Ghany of Minia University, Egypt. At the time both researchers were working at the University of East Anglia at Norwich, England. This work is partly based on empirical arguments, and on…
