An "up-to-date" application of algebraic techniques is described. The authors suggest that many such applications can be derived from newspapers and other sources. (SD)

The author argues that the "least number principle" (well-ordering for positive integers) is more intuitively acceptable to high school students than mathematical induction which can be derived from it. (SD)

Enrichment topics dealing with solutions of polynomials over modular systems are described. (SD)

A game modelled on football can be used to provide students with practice in solving algebraic equations. (SD)

A method of summing finite sequences by use of formal power series techniques is described. (SD)

Students collected and organized data concerning noise levels of various school activities. They reported that the activities were interesting and relevant. (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 methods are considered for finding the logarithm of a number using elementary arithmetic. (DT)

A technique is illustrated for solving relative motion problems using a maneuvering board and vector algebra. The technique can be used to visually illustrate properties of vector algebra in a non-theoretical context. (MP)

This research study shows that it is possible to advance the use of proportional reasoning of many secondary school students by means of a well-designed teaching program. (MP)

An example is discussed in which a drill exercise, initially involving whole number addition, can be used to develop concepts in equations of many variables. (MP)

Four problems are given and discussed involving reflection about a line or the reflection properties of conic sections. Solutions are given. (MP)

A graphical representation is used to construct a line one centimetre in length. (MP)

An investigation of these numbers is shown to give students an opportunity to make use of such mathematical skills as algebraic substitution, modular arithmetic, counting arguments, and mathematical induction. (MP)

A description is given of an Algebra II-Chemistry I combined high school class being taught in an attempt to coordinate chemistry topics with related mathematics topics. (MP)
