The goals and history of the Mathematical Olympiads for Elementary Schools are described. Teams, levels, and gender are discussed, as well as teacher training, administration, scoring, and awards. Sample problems are included. (MNS)

Presented are a series of word problems which give students the opportunity to use or develop problem solving skills. The problems are open-ended, with possible answers included. (JP)

Problem posters that focus on the use of information from a chart to find a solution are featured. One poster looks at the prices of picture postcards and is geared for grades one through three. The second poster, designed for levels four through eight, focuses on postage rates. (MP)

This section has four topics: (1) sample mathematical competency problems for Indiana Elementary Teachers circa 1920; (2) an unusual problem suitable for calculators; (3) a unique way for teaching rounding off numbers; and (4) student construction of problems that create words on calculator displays when they are turned upside down. (MP)

The task of finding the least number and the size of weights necessary to weigh every integral number of pounds from one to 40 is presented as a problem solving activity for elementary classrooms. (MP)

A special calendar chart is presented that can be used to find out what day of the week any date falls on during the 1980s. (MP)

The calendar provides elementary mathematics students with open-ended questions intended to engage them mathematically in high-interest activities. No answers are provided so that students are encouraged to look alone, or in small groups, for significant mathematical evidence to develop confidence and the necessary critical thinking skills. (JJK)

The possibilities that magazines have to offer in the teaching of mathematics with consumer-related problems are discussed. (JT)

A variety of calculator activities is described for developing problem solving skills without getting involved in tedious computations. (JT)

Four specific problems are presented, discussed, and extended to illustrate how diverse instructional strategies, materials, and resources can be used to develop problem-solving skills. (MP)

A description of a planet in the shape of a cube where everything was built from squares and parts of squares is presented. The story is used as a background for several paper folding exercises that explore several geometric shapes. Solutions to the problems stated are included. (MP)

Two teaching ideas that focus on baseball are presented with a poster provided for each. The first activity features baseball applications of addition, subtraction, and number concepts. The second uses a baseball setting with logic-oriented problems. (MP)
