This guide provides students with practice for all the major types of graphs they are likely to encounter. It includes information on graphs of various families of algebraic functions; bar, line, and circle graphs; the creation, reading, and interpretation of graphs; and the use of graphing calculators. (MVL)

Explores the effects of varying the coefficients in the general quadratic function using graphing calculators. (MKR)

Presents examples in which the graphing calculator can provide students with particularly valuable insights into some major statistics ideas such as random numbers. (ASK)

The calculator is used to obtain values for use in graphing curves. Three worksheets are included. (MP)

An example is given of a class of problems whose solutions require the use of a scientific calculator in order to plot the graphs. (MP)

Cooperative groups were given transparencies of eight regular inscribed polygons and overlays of corresponding circumscribed polygons and were asked to find the perimeters and ratios of perimeter to diameter. Transparencies give students a graphic illustration of limits. Includes reproducible worksheet. (NI)

Uses parametric equations and a graphing calculator to investigate the connections among the algebraic, numerical, and graphical representations of functions. (MKR)

Discusses various ways to explore graphs on the TI-82 graphing calculator by using the three different cursors: the free-moving, trace, and result cursors. (MKR)

Students have difficulty associating equations of vertical and horizontal lines with their respective graphs. Presents an activity using a TI-82 graphing calculator to eliminate this confusion and to strengthen students' understanding. (ASK)

This booklet contains a representative sample of the efforts of colleagues at 11 institutions to use graphing calculators to enhance the teaching of calculus and precalculus. The first section contains examples of graphs for teachers to choose from for presentations, including: simple examples to illustrate some standard ideas in precalculus,…

Illustrates exploration of composition of functions, translations, and inverse functions on a graphing calculator. Includes reproducible student worksheets. (MKR)

Attempts to answer and generalize the question: When is the numerical derivative obtained on the graphing calculator greater than the actual derivative, and when is it smaller? Discusses symmetric difference. (MKR)

Explores quadratic functions using the graphing calculator. Discoveries are made graphically whereas hypotheses are proven algebraically. Includes traditional quadratics, other algebraic quadratics, nonpolynomial quadratics, transcendental quadratics, and proofs. (MKR)

Many students have difficulties in interpreting position versus time graphs. Presents an activity involving calculator-based motion labs that allows students to bring these graphs to life by turning their own motion into a graph that can be analyzed, investigated, and interpreted in terms of how they actually moved. (ASK)

Active involvement and infusion of mathematics into familiar, everyday experiences are essential elements in challenging students to engage in true thinking. Presents an investigation on graphing that touches on all representations including tables of values, graphs, and verbal descriptions. (ASK)
