Presents the problem of doubling dough by creating a mixture of dough that doubles in volume every minute when placed in a warm oven. Discusses ways of proposing this question in the classroom. (ASK)

Describes a teaching experience through student-centered activities in a second year algebra class with gifted and talented students. Concludes that students learned more mathematics than the teacher originally planned to teach. (KHR)

Discusses drawing a Pythagoras diagram in the context of how computer software influences mathematical understanding. Requires different understandings of what the diagram involves in order to be successfully completed in different environments. Suggests that while LOGO is often expected to be easier, a graphic calculator can be less demanding.…

Examines possible cultural and socioeconomic status (SES) differences in the type, frequency, and complexity of 4- and 5-year-old American and Chinese children's everyday mathematical activities during free play. Results showed neither any differences between the types of mathematical activity American and Chinese children exhibit, nor in the…

Describes how three experiments suitable for upper-elementary students can be used to foster classroom discourse in which students begin to explore probability. (KHR)

Explores different types of Bingo games in which students can work on mental arithmetic, solve equations, and recognize geometric shapes. (KHR)

Describes how to teach the coefficient of determination and correlation coefficient. Includes a worksheet for correlation and regression activities. (KHR)

Correlates high school chemistry curriculum with high school algebra curriculum and makes the case for an integrated approach to mathematics and science instruction. Focuses on process integration. (DDR)

Discusses the New Orleans Center of Science & Mathematics, an alternative high school with an activity-based curriculum specializing exclusively in mathematics and science courses for inner-city students. (PKP)

Presents attributes of different types of software including Logo, geometric packages, graphical packages, and spreadsheets, each of which offers different opportunities for learning. Investigates the different ways in which the software allows for performing the given task so as to make the mathematics of the task explicit to users. (KHR)

Describes a classroom inquiry into expressing the number pi as the limit of a sequence of different ratios using relationships among coins and the radius of an inscribed circle. (KHR)

Describes an activity designed to demonstrate the birthday paradox and introduce students to real-world applications of Monte Carlo-type simulation techniques. Includes a sample TI-83 program and graphical analysis of the birthday problem function. (KHR)

Presents a problem entitled "Puzzling Prices" for grades K-6. Students are given a combination of price tags and must determine the different amounts of money that could be made using different combinations. (KHR)

Describes an activity in which children are given a visual indicator of a fraction with oil-and-water. (Author)

Describes how students connect culture and mathematics by using tessellating and symmetrical patterns in the designs of architecture, pottery, blankets, and baskets as models to create geometric designs for a quilt. (Author/YDS)
