Graphing skills are growing in importance in our information society, presenting facts and concepts in newspapers, magazines, and on television. Graphs incorporated into teaching develop children's problem-solving skills. Ways to use graphs in the classroom are discussed, and examples are given. (MT)

Describes the learning experiences of young children meeting stem-and-leaf plots for the first time. Presents a vignette that offers a real and dynamic example of how young children can learn, use, and evaluate this powerful statistical display. (Author/ASK)

The author suggests that slope be introduced as a topic independent of graphs, and that it be presented in a way that makes some sense of using a fraction to represent it. Many examples are included. (MNS)

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

Argues that the aggregate good is a powerful pedagogical device in economics. Uses a simple graphical analysis that demonstrates to the student the concept of an aggregate good, that preferences can indeed be collapsed from many goods to two. (DB)

Activities described for using zucchini to teach measurement include: guessing, graphing, and measuring length and weight; comparing sizes and shapes; and puzzles. (MP)

Graphing is an integrative skill because you can use it whether you are teaching measurement or geometry or number theory or most any other topic. It is also important as a mode of communication which can simplify a large amount of information. Here are five steps for effective presentation of graphing to young students. (Author/RK)

Suggests some aspects of the school environment which can initiate graphing experiences as well as present some guidelines for graphing. (Author/RK)

Considering a fraction as directions for graphing a line through the origin of the x-y plane is suggested. Strengths and weaknesses of the idea are also discussed. (MNS)

This discussion of ways to use spirolaterals in the classroom includes making conjectures, hypotheses testing, and proofs, as well as a number of examples. (MP)

Explores strategies in the situation of a runner trying to evade a tackler on a football field. Enables the student to test intuitive strategies in a familiar situation using simple graphical and numerical methods or direct experimentation. (JRH)

Described is how the crumpling of paper balls exhibits the concept of a topological dimension similar to fractals. The mass of the crumpled paper ball is found to be proportional to its diameter raised to a nonintegral power. (KR)

An exercise which relates particle scattering and the calculation of cross-sections to answer the following question--"Do you get wetter by walking or running through the rain?"--is described. The calculations used to answer the question are provided. (KR)

Grid paper activities are discussed as a way to help students conceptualize fractions. (MP)

Arrays are seen as excellent models for beginning multiplication examples, but that they are often put aside by teachers when they become unwieldly for greater factors, possibly depriving learners just when they need the help. The use of grids made on paper marked in squares is suggested. (MP)
