The digits in 1776 can be used in a variety of mathematical activities (especially during the bicentennial year). (SD)

The results of a survey on the use of eleven types of audiovisual materials by mathematics teachers in New South Wales are presented. (SD)

Identifying the larger (L), smaller (S) and difference (D) of two real numbers, and then selecting the appropriate relationship between L, D, and S can help students solve algebra word problems. (SD)

Three topics related to teaching mathematics are discussed: a problem with the order of operations, teaching fractions, and an application of the distributive property. (MP)

Described is a calculator race that is designed to require a fast touch with the calculator and also the ability to apply mathematical knowledge. Sample questions are given. (MP)

The students, the general aspects and emphases of the curriculum, and the equipment and texts are discussed. An abbreviated course outline and a brief self-evaluation of the program are included. (MP)

Results of operations on the Pythagorean formula are interpreted pictorially to yield interesting art forms. (MP)

A coordinate system is imposed on a geoboard to form a table that leads to the discovery of the formula n[(n+1)(n+1)] (n+2)/12. Proof is by induction. (MP)

Repeatedly taking the square root with a calculator yields numbers with logarithmic-type properties, which can be used to define the logarithm functions. (MP)

A situation is presented that is intended to lead to open-ended mathematical discussions that allow students to conjecture, discover, and prove mathematical statements. (MP)

Described is a technique developed to help beginning programing students with limited experience in both a computer language and computer logic write a successful game program in BASIC. (MP)

The operation of rounding is shown to lead into an investigation of an abstract mathematical system. Properties of the system are discussed and graphs of the rounding function are drawn. Some questions for discussion are given. (MP)

A magazine article is shown to contain material that could lead to discussions of several topics in mathematics. The article and the related mathematics are discussed in detail. (MP)

Computer programs for solving alphametics are discussed. A fortran program for solving a general additive alphametic is given. (MP)
