Problems involving the use of diagrams to depict plangers'' (in which lines cross a specified number of times) are discussed. (LS)

Implications for teachers from Piagetian-oriented piagetian-oriented research on problem solving reported in an article by Eleanor Duckworth are presented. Edward de Bono's Children Solve Problems,'' a collection of examples, is also discussed. (MS)

Solution of, and commentary on, a problem suitable for use in the secondary school mathematics classroom. Topics from arithmetic, algebra, and number theory appear in a unified way. (FL)

Presented are some of the special properties possessed by a triangle in which the measure of one of its three angles is one-half the measure of another of these angles. The author names such a triangle a vux triangle. (RP)

The problem of placing stamps on a grid is presented, with variable forms of the problem and various levels of the solution described. (MNS)

Procedures to help algebra students solve problems more efficiently are discussed, using linear programing graphs. (MNS)

Twelve games are described which serve to reduce students' mathematics anxiety. Children solve problems by observing, visualizing, manipulating, finding patterns, and using logical sequence. Some games do not involve numbers, but all games require original thinking and encourage intuition. (JMK)

Problems which can be solved or partially solved by the Gregory Interpolation Formula are presented. The formula is explained and applied to three problems. (MNS)

The hypothesis examined suggests that prequestions should be more facilitating than postquestions in directing students to the information necessary for a problem's solution. Fourteen problems were designed for a criterion measure, and 52 students in community college intermediate algebra classes were the subjects. Results indicated question…
