Presents an activity in which students draw a picture, analyze each line and curve, and write the symbolic equations represented by the graph. Includes reproducible student worksheets. (MKR)

Provides activities that introduce the sine and cosine functions in a hands-on manner. Includes ideas for assessment. Contains reproducible student worksheets. (MKR)

Presented are activities concerning the method of graphing the equation y=kx in the Cartesian and other coordinate systems. Students progress from the graph of a straight line to the investigation of conceptually related geometric loci in non-Cartesian coordinate systems. (MDH)

The issue of division by zero is discussed. Activities that cover the topics of measurement division, partition division, relationship to fractions, confusion with dividing into zero, dividing zero by zero, and relation to more formal numbers are presented. (KR)

This instructor guide, which was developed for use in a manufacturing firm's advanced technical preparation program, contains the materials required to present a learning module that is designed to prepare trainees for the program's statistical process control module by improving their basic math skills in working with line graphs and teaching…

Developed by educators from the Emily Griffith Opportunity School, this teacher's guide was developed for a 4-hour workshop to teach employees how to read the charts and graphs they need in the workplace. The unit covers four types of graphs: pictographs, bar graphs, line graphs, and circle graphs. The guide is divided into four sections: reading…

This activity, one in a set of teacher-developed instructional activites for elementary-level geography, investigates the problems and promise in meeting the nutritional needs of the world's people. Graphs are the principal media for instruction. Thirty-nine statements are given from which students choose ten that show promise for feeding the…

Brief articles are included on creating in first-year algebra, making a Moebius hat, and graphing cubics. (MNS)

The activities presented deal with representing student-collected information by means of reusable teaching aids such as pictorial graphs, tally charts, bar graphs, and circle graphs. Directions for making three of the teaching aids described are included. The activities are seen as supplements to drill and practice. (MP)

Describes a classroom activity designed to give students hands-on experience using technology and geometric visualization, as well as to explore fractal geometry in a cooperative classroom environment. Natural phenomena is the context of these activities. Enriches understanding of Euclidean geometry and infinite sequences. Lists materials,…

Presents activities in which students study exponential growth and decay by collecting data, constructing graphs, and discovering algebraic formulas. (MKR)

Describes the work of a meteorologist, the history of meteorology, and links to mathematics. Contains reproducible student activity worksheets on weather data. (MKR)

Describes the use of glyphs, simple pictures or graphs whose parts represent information about a given subject, in a second-grade classroom. Includes many examples. (MKR)

Demonstrates that the functions known as the witch of Agnesi and the normal distribution are not identical by comparing the areas under the curves and the slopes of the lines tangent to the curves of the two functions. Suggests follow-up activities to the investigation. (MDH)

This article describes a social studies project for deaf students, which used the search for information concerning people with deafness to develop student skills in creating and interpreting various kinds of charts and graphs. (DB)
