Presents a discovery activity that connects mathematics and the world of entertainment. Combines geometric transformations with a calculator's DRAW, MATRIX, and PRGM features to generate visual reinforcement of mathematical concepts. (Author/NB)

Describes an instructional sequence that promotes student understanding of a coordinate system while simultaneously facilitating understanding of linear relationships. (Author/NB)

Describes a method for teaching Euler's line, the co-linearity of the circumcenter, centroid, and orthocenter of a triangle. Discusses teaching results. (KHR)

Aims for students to use a combination of stochastic ideas to simulate a basketball tournament. Uses the TI-83 calculator in the activity to simulate the binomial distribution. (KHR)

Discusses reasons for using spreadsheets in mathematics education. Presents mathematics activities for beginning algebra classes using spreadsheets. (ASK)

Presents a mathematics problem that emphasizes looking for patterns and organizing one's efforts, and a vignette that exhibits classroom efforts while solving the problem. (ASK)

Evaluates the use of modern CAD methods to solve geometric problems. Solves descriptive geometry problems using the layout and position of the successive auxiliary views from the projection of three-dimensional figures onto a two-dimensional plane of paper. (CCM)

Presents an investigative process of conjecture followed by proof by induction using a combination of manipulatives and technology, placing special emphasis on the use of different representations. (ASK)

Describes an activity in which students present two mathematics-related quotations, one written by a famous mathematician and one original statement that they themselves have written. Encourages students with different strengths and learning styles to participate more fully in the lesson. (ASK)

Provides a set of classroom activities or steps that can be used to determine the area of a triangle on a sphere. (ASK)

Errant mathematical views are widely found among teachers, their students, and authors of applied mathematics texts. Suggests classroom experimentation, both to confirm the occurrence of these errors, and to apply the appropriate corrective teaching. (Author/ASK)

Focuses on three activities using the TI-92 graphing calculator that examine the relationship between the intensity of a light source and its distance from a measurement point, properties of a sound wave, and the relationship between the time elapsed and the temperature of a cooling substance. (ASK)

The ability to undertake approximate calculations and to get a rough feel for data is an important skill which should not be overlooked. Presents some ideas for teaching and assessing approximate calculation. Contains 13 references. (Author/ASK)
