Mathematics Teacher, 1992
Two methods to facilitate classroom management and initiate student responsibilities are presented. The first describes student responsibilities for making up missed tests or assignments. The second describes a student scorecard to help students keep track of their grades and act as a motivational technique. (MDH)

Moody, Mally – Mathematics Teacher, 1992
A series of four activities are presented to enhance students' abilities to appreciate and use trigonometry as a tool in problem solving. Activities cover problems applying the law of sines, the law of cosines, and matching equivalent trigonometric expressions. A teacher's guide, worksheets, and answers are provided. (MDH)

Mathematics Teacher, 1992
In the first part, both the rationale and the policies for allowing students to use notes during tests in an advanced class are presented. The second part contains suggestions for color-coding a grade book thus promoting efficient information retrieval and easier analyses of students' progress and/or grades. (JJK)

Mathematics Teacher, 1992
Part I describes the presentation of six different proofs of the Pythagorean Theorem by groups of three students in a party atmosphere. Part II delineates the analysis behind a student conjecture concerning the area of certain closed polar-coordinate figures. Part III proposes a categorical worksheet for determining when to apply the proper rule…

Mathematics Teacher, 1992
Two trigonometry problems are presented. The first compares the graphs of the functions arcsin[sin(x)], arccos[cos(x)], and the identity function f(x)=x. The second, using the law of cosines, demonstrates that the solution of a triangle knowing two sides and the excluded angle is no longer ambiguous. (MDH)

Blomquist, Ann; Steman, Pamela Wheeler – Mathematics Teacher, 1991
Tips are given on how and when to use videotaped lessons to provide for continued classroom productivity in spite of anticipated, or even unexpected, absence of the mathematics teacher. In an accompanying article, a graphical approach to determine whether a limit exists is explored with numerous examples and illustrations. (JJK)

Swetz, Frank – Mathematics Teacher, 1991
Following a brief historical review of the mechanism of mathematical modeling, examples are included that associate a mathematical model with given data (changes in sea level) and that model a real-life situation (process of parallel parking). Also provided is the rationale for the curricular implementation of mathematical modeling. (JJK)

Crouse, Richard J.; And Others – Mathematics Teacher, 1991
The first idea concerns a board game similar to tic-tac-toe in which the strategy involves the knowledge of the factorization of quadratic polynomials. The second game uses the calculation of the surface areas of solid figures applying the specific examples of cigar boxes and cylindrical tin cans. (JJK)

Pleacher, David – Mathematics Teacher, 1991
Presented are student activities that involve two standard problems from geometry and calculus--the volume of a box and the bank shot on a pool table. Problem solving is emphasized as a method of inquiry and application with descriptions of the results using graphical, numerical, and physical models. (JJK)

Whitman, Nancy – Mathematics Teacher, 1991
Provided are student activities to introduce the geometric concepts of line symmetry and rotational symmetry as related to Hawaiian quilting patterns. Paper squares, scissors, and folding techniques afford the teacher the chance to stimulate class discussion about pattern recognition and to integrate mathematics with the cultural world outside the…
