Provided is a mathematical recreation to strengthen student mathematics skills. The object of the activity is to build up an expression using the four digits of the current year, without rearranging the digits and using combinations of operations, to equal a prescribed value. Descriptions and examples are included. (RT)

Discusses making tessellations by using a polyomino. Illustrates the various ways for various shapes of polyomino. Provides several diagrams and instructional guides. (YP)

Presents one model for a liberal arts mathematics course that combines probability and calculus. Describes activities utilized in the course to heighten students' interest and encourage student involvement. Activities include use of visualization, take-home tests, group problem solving, research papers, and computer usage with DERIVE computer…

Discussed is a method of approximating the roots of a quadratic that allows the discovery of relationships between parabolas and circles and between the use of geometry and algebra. Included are the procedure and justification of the method. (KR)

Discussed is the type of evidence children find to be convincing using either empirical or deductive methods to justify propositions which they consider to be true. Included are the problem, research design, and the conclusion. (KR)

This section includes eight problems to which the journal invites readers to respond. Problem topics include angles in alternate segments, pentominoes, a new triangle of numbers, cricket scores, symmetrical pentagons, inequalities, a pythagorean dissection, and magic squares. (MDH)

Discusses how students at the end of the French primary school-cycle (10- to 11-year-old pupils) resolve multiplication and related division problems within an assessment perspective taking into account the 3 factors of the problem's representational structure, the numerical values used, and the context of the problem statement. (25 references)…

Compares the practice of using drawings in story problems in Japan and the United States and includes recommendations for teachers in the United States. (Contains 14 references.) (MKR)

Discusses opportunities to use nursery rhymes to aid in the mathematical development of young children. Considers rhymes that involve patterns, ordering, and problem solving. (MKR)

Two geometry problems generated from a design problem involving a shuttle return mechanism in a weaving machine are presented. The solutions to these problems are detailed. (CW)

Gives examples of, and a rationale for, using estimation in the classroom daily. Includes instructional tips and strategies to enhance estimation activities. (MKR)

In today's society, changes in technology have made estimation skills more important than ever in the development of mathematical power. Presents a schoolwide activity in which students participate in a mathematical contest on estimation. Concludes that, in devising their estimates, students have practiced their problem-solving and sense-making…

A three-stage model for algebraic word problem solving is developed in which students' understanding of the intrinsic logical structure of word problems is strengthened by connecting real-life problems and formal mathematics. (Contains 3 figure.)

In early algebra students often struggle with equation solving. Modeled on Streefland's studies of students' own productions a prototype pre-algebra learning strand was designed which takes students' informal (arithmetical) strategies as a starting point for solving equations. In order to make available the skills and tools needed for manipulating…

This article describes the process used in elementary mathematics content courses to engage preservice teachers in problem-solving activities to enhance their understanding and ability to analyze nonroutine problems. Through this process, preservice teachers' competencies and confidence with these problems improve. (Contains 7 figures.)
