This brochure contains an activity for grades 9-12 that involves students in an examination of real versus perceived risks. Students perform a risk factor analysis, and evaluate benefits and risks of energy sources. The activity can be conducted by individuals or small groups. Students rank a series of life-threatening risks and compare them to…

Presents an investigation using data collected by students to explore timelines and pie charts. The activity begins with having students keep a chronological record of their activities for one 24-hour period to create and analyze pie charts that show how they have spent their time. Activity sheet also included. (ASK)

Compares observed to expected counts of white, African American, and Hispanic major-league baseball players (n=650) in 1989. Uses chi-square values to determine that racial differences are highly significant for pitcher, catcher, shortstop, and outfielder. Includes appendix with 1993 player counts and seven suggested student activities. (SEW)

A graphing activity which allows students to work independently of the teacher and the textbook is described. The activity involves providing data in order to develop the skills necessary for interpreting the collected information. (JT)

Reasons for having students make graphs are noted. Then specific graphing topics and materials appropriate for young learners are presented, including life-sized, floor, clothespin, felt-face, block, and magnetic graphs, and polls of pupils. (MNS)

Teachers of an integrated elementary classroom used cookie-sharing time as a learning experience for students. Responsible for dividing varying amounts of cookies daily, the students learned to translate their experiences to graphs of differing sophistication and analyses. Further interpretation and application were done by individual students…

Three examples of graphing-and-predicting activities that can be used with elementary school children are described. (DT)

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)

An alternative approach is described for presenting the idea of the derivative through the use of chords of a graph. (MP)

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,…

This activity unit provides an example of how the construction and interpretation of graphs can be incorporated into elementary classroom activities. (MP)
