Investigates an interesting application of probability in the world of sports. Considers the role of permutations in the lottery system used by the National Basketball Association (NBA) in the United States to determine the order in which nonplayoff teams select players from the college ranks. Presents a lesson on this topic in which students work…

Presents activities designed to engage students in an experiential and theoretical application of problems in precalculus and to study geometry, coordinate systems, rates, linear applications, and the concept of function. Illustrates problem situations and includes student worksheets and a teacher's guide. (KHR)

Presents problems designed to focus student attention on the visual representations that accompany the verbal statements of problem situations involving motion over a period of time. Shows that as a result of engaging in these activities, students gain a better understanding of a given problem situation before they apply procedures to answer…

Presents activities providing a cultural journey through history that allow children to understand that many mathematicians have contributed mathematical thoughts and ideas. (KHR)

Provides details on how technology can be used to examine the symmetry of human faces and to experience symmetry being created instead of observed. (Author/YDS)

Explores the mathematical thinking preschoolers engage in when reading or even pretending to read. (Author)

Presents responses to the Marbles problem, which explores the many ways to arrange a given number of square tiles. (Author/YDS)

Describes mathematics activities based on food as a theme. (Author/YDS)

Discusses a meaningful experience, conceptually, of multiplication of fractions. (Author/YDS)

Demonstrates how an investigation of measurement and representative numbers can engage all levels of student ability. Asks students to learn about representative numbers in order to answer a question they find intriguing. (YDS)

Presents an activity, "Lisa's Lemonade Stand," that actively engages students in algebraic thinking as they analyze change by investigating relationships between variables and gain experience describing and representing these relationships graphically. (YDS)

Describes the work of one mathematics teacher as she uses literature to make factorials both interesting and comprehensible to middle school students. (Contains 10 references.) (YDS)

Presents a measurement problem that can be explored by students of varying ability. Discusses aspects that make it accessible in a heterogeneous class. (YDS)

Presents a mathematics activity that teaches binary code. (YDS)

Uses a Calculator-Based Ranger and a graphing calculator in problem-solving mode to introduce an exploration of graphing-related concepts including intercepts, slopes, and rate of change. (YDS)
