Article investigated solutions for storing and releasing pets used for learning processes in the classroom. (RK)

Detailed is a strategy for teaching the transformation of word problems into equations, equation systems, or inequalities. Classroom experiments using the method are described and are favorable. The underlying philosophy of the method is that the transformation will be accomplished by means of comprehension at first, but in the second stage the…

Students were presented with the problem of finding all magic squares of order three. (SD)

A small-group tutorial technique is described that develops creative thinking in students having difficulties in problem solving. (MP)

Undergraduate history students can gain insight into the historical process from a short exercise using copies of documents that give conflicting interpretations of the same event. Explains how to lead class discussions based on two letters about lawlessness in Arizona in the 1880s. (Author/AV)

This article examines the Pythagorean Theorem from a geometric point of view by suggesting some natural extensions of the theorem. The use of a more general theorem to prove a difficult one is suggested, where possible. The article includes figures and proofs. (Author/MA)

The vast majority of people are most familiar with arithmetic in base ten. This article presents a follow-up on a problem with several divisibility tests valid in base ten which are related to Freitag's general test and which follow directly from it. Base 13 is also explored. (Author/MA)

The paper-and-pencil game "Tri" is described. The authors argue that students gain logical skills by playing the game, and that the game lends itself to the introduction of diverse mathematical ideas. (SD)

Timing stoplights and trying to determine the best way to allocate cycle time to the two directions is discussed. The simple case and improving the model are both considered. (MNS)

The meaning of problem solving and investigations, what investigations are intended to achieve, the teacher's role, and how to introduce investigations in the curriculum are discussed. (MNS)

Use of a checkbook can hook even the most reluctant mathematics students into learning mathematical and problem-solving skills. (CB)

Presents several examples of algebraic word problems and demonstrates how spreadsheets are used to solve the problems. Spreadsheet templates are included to illustrate how each problem is solved. (MBR)

Solutions to a problem on seating arrangements and one on a box-office situation are discussed; a statistical approach is used. Four computer programs are included. (MNS)

One view of mathematical thinking is described, followed by detailing of the characteristics of a problem-solving program necessary to develop this kind of thinking. (MNS)

Use of the computer to simulate or imitate probability problems that are difficult to analyze in any other way is discussed. How the Monte Carlo method works is clarified, with sample problems and programs. (MNS)
