The author suggests having students work on the related inequalities to given equations comparing and graphing the three solutions on the same number line. Using individual activity cards, the student picks replacements and computes, continuing this process until they can determine the complete solution. (LS)

Plane figures constructed with curves of constant width "roll" evenly. The circle is but one example of such figures. Presented is an activity to direct students in the construction of a plane figure with curves of constant width which is not a circle. (JP)

Article details eight creative arts learning stations planned to develop construction art and design skills in elementary school students. (GB)

Worksheets introducing the concept of loci as paths of points moving under specific conditions are presented. (DT)

The organization of a class project involving the writing of a book on matrix algebra is described; benefits of the project for both the students and the teacher are discussed. (DT)

By changing the Euclidean metric definition, a new geometry is developed. Properties of figures are analyzed and theorems are proven in this new system. (DT)

The history of the geometrical design found on charts and compass cards is given, and directions for constructing the design are provided. (DT)

Two games, a barn dance and football game, are described in which the rules and the strategies are based on the composition of elements of the Klein-four group. (DT)

The concept that measures fall within intervals is discussed, and suggestions are given for teaching techniques and for student activities emphasizing this concept. (DT)
