Provides detailed instructions for constructing a pattern and, then, making a shirt suitable for use in classical and period plays. Suggests variations to adapt the shirt to specific needs. (JMF)

Number patterns discovered by third graders are described and discussed. (MK)

Magic circles, number puzzles somewhat more complex than magic squares, are described and discussed. (MK)

In this "thank-you" letter to Mr. Pascal, many applications for Pascal's triangle are pointed out. (MK)

An activity is presented which provides a novel approach to number patterns, experience in following an unusual algorithmic procedure, and practice in systematic search techniques and basic facts. (MK)

The article includes a short history of polygonal numbers, a method for finding the root of a polygonal number, and suggestions for using polygonal numbers in the classroom. (MK)

Describes apparatus and procedures to design and construct a "printing box" as a graphic arts project to make color prints on T-shirts using photography, indirect and direct photo screen methods, and other types of stencils. Step-by-step photographs illustrate the process. (MF)

The authors develop the idea of Niven numbers and discuss their potential usefulness in the classroom. A computer program to generate Niven numbers is provided. (MK)

Using the seasons in the science classroom increases student observation skills as they focus on subtle differences such as shades of color and differences in structures. In this article, the author presents a variety of activities that can help students identify and demonstrate patterns and changes in leaf or plant development. The ability to…

The mathematics curriculum should be imbedded into the cultural environment of the student. Discussed is the mathematical educational potential of decorative motif. (PK)

Mathematical activities suitable for reproduction as worksheets are suggested. These activities are adaptations of the classic tower puzzle and are intended to help students discover patterns, make generalizations, and use the strategy of solving simpler problems in order to solve a more difficult one. (MK)

Worksheets for duplication are provided for this activity designed for students in grades 6-10. The objective of the activity is to have students discover generalizations about the patterns formed. (MK)

Discusses the use of flexible straws for teaching properties of figures and families of shapes. Describes a way to make various two- or three-dimensional geometric shapes. Lists eight advantages of the method. (YP)

Describes the stages of a process of reflective thinking. Investigates how geometrical models can be used in learning and teaching mathematics in connection with the process. Identifies two models for children of age four to eight: constant path in the space of shapes and continuous path of varied polygonal shapes. (Author/YP)

Uses pentominoes to examine the concepts of congruence, similarity, transformations, tessellations, networks, perimeter, area, and volume in a problem-solving, cooperative learning environment. Discusses the construction of three-dimensional pentominoes. (YP)
