Several games, which can be useful in the classroom for teaching problem solving strategies, are described. (SD)

After a unit on Euclidean geometry which stresses both the development of intuition and the use of deductive methods, non-Euclidean concepts are introduced by having students read and consider science fiction stories. (SD)

Referring to several examples, the author argues that more time should be spent developing statistical concepts such as randomness and independence before developing mathematical models for statistical computations. (SD)

Analyzing the effects of tilting a probability board can be an effective method of introducing a discussion of models in a probability class. (SD)

Problems involving the generation and counting of isosceles triangles interior to a given isosceles triangle are described. (SD)

Students in nine classes were randomly assigned to treatment groups receiving (1) written comments on their homework papers or (2) no comments. In two of the classes, the students receiving comments showed achievement superior to that of the others. In the remainder of the classes there was no difference. (SD)

The author discusses the impact of mathematical developments around the turn of the century, and historical concerns and development of mathematics education. This article is a continuation of SE 515 504. (SD)

A series of maps is presented for coloring with the fewest possible colors. (SD)

A survey of more than 6,000 secondary-school students was conducted to determine student perceptions of their teachers and classes. The results concerning mathematics classes are summarized in this paper. Implications for instruction are discussed. (SD)

By experimenting with measurement on regular and irregular surfaces, students can give an appreciation of the nature of the measurement process. (SD)

The algorithms for finding cube roots is approached by slicing a cube. (SD)

Using mirrors mounted on a plywood base to study reflections provides an introduction to the study of transformation. (SD)

Rational points in the plane were defined as points having both coordinated rational. Students solved several problems linking rational points with lines, circles, and other geometric figures. (SD)

Two worksheets can be duplicated for use in activities related to estimating liquid measurements. (SD)

Similar rectangles are the basis of a set of activities using newspaper. Topics arising include infinite series and Pythagorean theorem. (MP)
