Argues that by celebrating the number pi with special mathematical activities we may be teaching the fundamental concept of the place-value structure of our decimal place system. Includes several examples to illustrate the argument. (MM)

Discusses the effects on healing of attitude, positive thinking, and affirmations. Presents a mathematical example of hypothesis testing. Results point to the desirability of discussing such ideas with students to emphasize that the use of hypothesis testing is not simply a mechanical procedure. (ASK)

Helps students identify the animal that corresponds to the year of their birth according to the Chinese zodiac. Defines the structure of the Chinese zodiac so that the subsets of compatibles and opposites form closed substructures with interesting mathematical properties. (ASK)

Presents an experiment to test the statistical hypothesis that Oreo Double Stuf cookies contain twice as much filling as traditional Oreo cookies. (ASK)

Discusses how students construct their own understanding of mathematics as they discover and then learn it in class. Presents Krystal's method to subtract mixed numbers that her peers adopt and name for her. (ASK)

Uses the average-monthly-temperature function as an application of the sine wave. Argues that the attractive aspect of gas bill graphs is that they clearly illustrate that sinusoidal curves are useful and meaningful in an everyday context. (ASK)

The unique factor of the Japanese educational system is the use of entrance examinations. Presents examples and comments on questions from those examinations. (ASK)

Describes one innovative method that can help middle-grade students become more flexible in their ability to represent fractions, decimals, and percents, and creates a game of concentration using those mathematical subjects. (ASK)

Presents a mathematical analysis of the game "twenty-four points" that aims to apply arithmetic operations on the four numbers to reach a specific number. This game can improve children's ability to do mental arithmetic. (ASK)

Presents a mathematics activity in which equal areas and volumes are focused upon when sharing a circular pie. (ASK)

Introduces the use of the game Battleship to study the system of equations and the distance formula. (ASK)

Decribes a variation on Bingo that provides a non-routine probability investigation through which students develop concepts of chance. (Author/CCM)

Illustrates how upper elementary grade students can develop an understanding of the invert-and-multiply algorithm. (CCM)

Explores the derivation of empirical models for the stopping distance of a car being driven at a range of speeds. Indicates that the calculation of stopping distances makes an excellent example of empirical modeling because it is a situation that is readily understood and particularly relevant to many first-year undergraduates who are learning or…

Presents activities designed to be worked on by parents and children together, and describes experiences in using the activities in school and home settings. Reviews patterns and arithmetic. (MM)
