If students are to understand inferential statistics successfully, they must have a profound understanding of the nature of the sampling distribution. Specifically, they must comprehend the determination of the expected value and standard error of a sampling distribution as well as the meaning of the central limit theorem. Many students in a high…

Five activities are presented in this student workbook on using the electronic calculator. Following the directions for using the machine, problems are given on multiplying and dividing, finding percentages, calculating the area of assorted polygons, changing fractions to decimals, and finding squares and square roots. (JH)

Student access to programmable calculators and computer terminals, coupled with a familiarity with baseball, provides opportunities to enhance their understanding of the binomial distribution and other aspects of analysis. (MP)

Describes a sampling game originally based on a sampling bottle but here played on a graphing calculator as a way of introducing the topic of sampling in statistics. (MKR)

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

References on calculators are provided for elementary school teachers. These references (grouped according to background reading, ideas for students and teachers, and child-ready material) include author(s), title, source, and a brief description. (JN)

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)

Although the nature of the research varies, as do concepts of angle, research in general supports the supposition that angle is a complex idea, best understood from a variety of perspectives. In fact, the concept of angle tends to be threefold, consisting of: (1) the traditional, static notion of two rays meeting at a common vertex; (2) the idea…

This document is a collection of lesson plans written by 18 of Ohio's outstanding teachers chosen by the Ohio Council of Teachers of Mathematics. Each lesson plan includes reflection questions and some contain worksheets. Lesson plan titles for primary grades (grades 1-3) are: "Munching Fractions;""Math and…

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,…

Described is a calculator race that is designed to require a fast touch with the calculator and also the ability to apply mathematical knowledge. Sample questions are given. (MP)

Repeatedly taking the square root with a calculator yields numbers with logarithmic-type properties, which can be used to define the logarithm functions. (MP)

Comparing calendar years and planetary years serves as the basis of a calculator problem. (MP)

A program is presented which enables a programable calculator to become a device to check the arithmetic computational skills of students. (MP)

Presents activities to help teachers use the calculator. The type of logic, keystroke errors, and the constant are each discussed. (MNS)
