Presents two activities involving number sense in and around the shopping mall. Activities include estimation, measurement, and applications using percent. Concludes that it is appropriate to help students visualize numbers, particularly large numbers, in a context that is familiar and will be constantly reinforced. (ASK)

Describes the use of math journals in one kindergarten classroom. Asserts that use of the journals, in which children record their problem-solving processes, makes them think about and use various symbols to represent their thoughts; keeps them actively involved in reasoning, comparing, counting, and other mathematical concepts; and encourages…

Presents historical mathematics to students. Suggests allowing students to have two methods of problem solving with a graphing calculator to allow for a visual result. Indicates that students should have more than one opportunity to experience a solution to a problem, a variety of contexts for the problem, and an opportunity to communicate. (ASK)

Describes a series of lessons designed to supplement textbook instruction of probability by addressing the ideas of "equally likely,""not equally likely," and "fairness," as well as to introduce the difference between theoretical and experimental probability. Presents four lessons using The Wind Racer games to study probability. (ASK)

Presents a summary of the studies done by the Edinburgh Centre for Mathematical Education (ECME) on the use of practical activities in secondary schools. Argues that teachers may remain doubtful about the benefits of practical activities until they try them for themselves. (ASK)

Presents an activity for students to investigate equal parts and area and the connection between area and fractions. Highlights the importance of such a lesson in which children explore rich mathematical ideas, share their thinking and their work with one another, and make connections to other mathematical ideas. (ASK)

Observed and interviewed four preschool teachers to identify contributions of child care experiences to young children's mathematics understanding. Found that programs did not differ in amount or content of mathematics presented to children. Although teachers said they believed that mathematics was important and they engaged in mathematical…

Describes a very successful attempt to teach fractions to year 5 pupils based on pupils making their own fraction pack. Children decided for themselves how to make the fractional slices used in the activity using colored cardboard sheets and templates of a paper circle consisting of 24 equal slices. (Author/NB)

Introduces a math club for girls developed by a middle school teacher designed to encourage more girls to become engaged in mathematics. Describes the background of this project, programs included in the project, and parent reactions toward the program. (KHR)

Presents activity pages containing world population data for students to use to predict future population figures and Consumer Price Index (CPI) data to track changes in the costs of the goods. Includes answer key. (KHR)

Introduces human graphing by having students standing on certain coordinates instead of points plotted in ink. Includes teacher tips for success and possible graphing explorations. (KHR)

Investigates the effects of inquiry activities on a dynamic geometry environment designed to confront students with contradictions and uncertainties. Characterizes epistemological, didactic, and cognitive aspects of the activities. Analyzes the interplay among these three aspects, students' investigations, and their explanations. (Author/KHR)

Presents activities that focus on the mathematical opportunities that abound as part of the Olympic Games. (KHR)

Suggests that the history of mathematics is a fluid field within which lively debate occurs. Shares a math problem that requires a community of scholars to simulate the process by which the history of mathematics is actually developed. (KHR)

Describes Kerf bending which is used to produced a curved shape out of plywood. Discusses why Radtke's kerf-cut method yields a circular arch. (KHR)
