Involving students in generating and solving their own problems is proposed. A method for generating problems by using a number puzzle is presented. Ideas for using the "what if not" technique are also given. (MNS)

Included in this section are brief articles on making up a story to explain a graph, the inverse of a function of a single variable, and exotic horse-race wagering and combinatorics. (MNS)

Activities involving estimation of the number of objects in a configuration can motivate students to consider parametric models. (SD)

Arguments for and against the use of hand calculators in school mathematics are presented. (DT)

Worksheets are provided which lead students through an exploration of symmetry groups of geometric figures. (DT)

The place of binary arithmetic in the curriculum is discussed, then uses of binary coding for methods of automatic error correction in computers and calculators are analyzed. (DT)

Guides for teaching measurement and the metric system are presented. (DT)

A model for integer multiplication is discussed. (DT)

Queuing theory is explored by considering a simple example and by simulation with a computer. Sample BASIC computer programs are included. (DT)

This listing of 15 metric education projects receiving USOE grants is a continuation of the list given in Volume 4, Unit 5, 1976 issue of this journal (SE 517 535). The director, the institution, the exact amount of funds awarded, the name, and the location of each project are given. (DT)

A sequence of activities leading to the concept of Pi is suggested. (DT)

The use of DeMoivre's Theorem, the Binomial Theorem, and Pascal's Traingle in finding cos nx and sin nx is explained. (DT)

Directions are given for making a cheap, safe, durable geoboard. (DT)

Data from an electrocardiagram are analyzed mathematically in order to determine specific heart abnormalities. The mathematics behind one such problem is explained. (DT)

A card game is described which gives students practice with adding integers and which also develops the concept of "opposite." (DT)
