This project opens a conversation about the use of discourse as the basis for encouraging students' mathematical thinking in classrooms and supporting professional growth. A collaboration of teacher practitioners and Math Forum staff, it reflects an attempt to integrate practice and research, reporting on findings culled from discussions of…

This paper presents two mathematics activities that model functions studied using the Calculator Based Ranger (CBR) software for TI-82 and TI-83 graphing calculators. The activities concern a bouncing ball experiment and modeling a decaying exponential function. (ASK)

This book contains a set of versatile enrichment exercises that cover a very broad range of mathematical topics and applications in algebra from the Moebius strip to the googol. Several criteria have been used in developing the activities and selecting the topics that are included. All of them bear heavily and equally on concerns for curriculum…

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 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)

Describes how school improvement goals align with the Illinois Learning Standards to ultimately develop a school's mathematics goals. Reports that "Math Wizard Wednesdays" were offered as part of a school-wide goal, and as an intervention for students and staff that served as an ongoing reminder of improvement goals. (Contains 11 figures…

Investigates ways to analyze change in various contexts. Focuses on computer technology providing contexts for children's investigations of patterns of change and helping to develop foundational ideas of algebra and calculus. Discusses relationships between patterns of change, fundamental algebraic notions as linear and nonlinear functions, and…

Describes an activity that engages pupils in the whole statistical process from collecting data to interpreting the results. Discusses the importance of these activities in developing knowledge, skills, understanding, and ability in problem solving. (Author/ASK)

Considers how the World Wide Web is used by mathematics educators and describes a multiphase teaching experiment designed to determine if the World Wide Web is a viable means of accessing course materials. Discusses the resources involved in supporting such access. (DDR)

Explains that, although mathematics is essential for calculating time, the calendar is an historical construct. Demonstrates why there is no true way of measuring time and looks at the historical roots of the western calendar. Offers further readings on calendars, time, and the millennium. (ASK)

Presents the President's address from the 1999 annual meeting of the National Council of Teachers of Mathematics (NCTM). Asserts that the mathematics classroom teacher must create an environment that supports students and mathematics growth at many different levels, and suggests ways in which to achieve this. Considers the changing societal…

Presents examples of mathematical experiences and investigations for preservice teachers. Discusses potential benefits of the suggested mathematical experiences for the personal and professional growth of teachers. Contains 21 references. (Author/ASK)

Presents a variety of problems for elementary and secondary school students that focus on probability. Activities involving coins, M & M candies, and the game show "Let's Make a Deal," are described, and Web sites for the activities are listed as well as sites for lesson plans. (LRW)

Suggests that teachers could write problems to suit student populations in their schools and in the process of doing so encourage discussion, reflection, and writing by their students on mathematical language. Presents a series of games for the creation of equations for Year 7 students. (Contains 13 references.) (ASK)
