Peer reviewedOwens, John E. – Mathematics Teaching in the Middle School, 1995
Describes how graphing calculators can be used to explore different functions, from linear to higher degree polynomials. "Globs" (circles) are drawn around randomly plotted points on the screen, and students devise functions that pass through as many of these globs as possible. Variations on the game are also mentioned. (DPM)

College algebra is currently being taught using graphing calculators such as the TI-81. This document presents exploratory and problem solving activities that have resulted from classroom experiences with the TI-81. The activities have been designed to enhance the learning of some standard college algebra topics through the easy access to…

Peer reviewedDonley, H. Edward; George, Elizabeth Ann – Mathematics Teacher, 1993
Demonstrates how to construct rational, exponential, and sinusoidal functions that appear normal on one scale but exhibit interesting hidden behavior when viewed on another scale. By exploring these examples, students learn the importance of scale, window size, and resolution effects in computer and calculator graphing. (MAZ)
