Using the calculator to do addition and multiplication in base 2 is discussed, with the stress on how to change numbers from one base to another using the calculator. (MNS)

An activity is described for introducing some fundamental notions in inferential statistics to students in elementary high school statistics courses. (MP)

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

Archimedes' method for estimating the value of pi is developed and compared with the Gregory-Machin infinite series method. Programs for the TI-81 calculator for finding the upper and lower bounds using the classical method and estimating pi using infinite series are provided.(Author/MKR)

Presents activities involving equal sharing, weighted averages, mean, median, mode, average cubes, and iterated averages, the last of which involves the use of a spreadsheet or graphing calculator. Includes reproducible student worksheets and questions for discussion. (MKR)

These worksheets represent gameboards designed to provide practice in estimation using a calculator. Worksheets are presented for estimation in addition, sums and differences, products, and quotients. (MP)

Shortcuts to use when performing operations with the calculator are given. Algorithms discussed include reciprocals, powers, parentheses, infinite series, and synthetic division. (MP)

Provided are four worksheets that are designed to capitalize on the use of calculators as teachers' partners in helping students to develop an intuitive feeling for percentage. Students also learn how to use the calculator's percent key to compute percentages. (MNS)

Activities concern exploring data and using the stem-and-leaf plot for displaying data. The three worksheets present activities, with brief directions for the teacher included. (MNS)

This paper discusses different ways of using statistics more creatively. One method begins with two conflicting headlines from newspapers and analyzes them statistically by using a graphing calculator. Other activities using graphing calculators are also presented. (ASK)

Five calculator activities are described that are designed to explore ordered operations. Suggestions are given on mathematical objectives, strategies for solving, and possible extensions or follow-up activities. (MP)

An account is given of the use of the calculator and Cuisenaire rods in examining decimals that result from the division of whole numbers. (MP)

Activities are described in which the calculator is used for extending students' knowledge of place value and of basic arithmetic operations. (DT)

Describes an activity in which students are given a set of designs and are required to use their electronic grapher to reproduce the designs. The activity reinforces students' understanding of lines and of the formula for a linear function. (MKR)

Presents the Fibonacci sequence in a format that is readily implemented using the table and list features of the Texas Instruments TI-82 graphing calculator or a spreadsheet. Includes questions and investigations that can be explored using these tables and lists. (MKR)
