Problems short on computation and long on logical thinking are suggested for development of logical thinking. A set of such problems is presented. (MP)

Discusses the implementation of the National Council of Teachers of Mathematics standards, especially problem solving, into the elementary mathematics curriculum. Presents three examples: measurement and seriation at the primary level; place value for intermediate level; and spatial reasoning and logical thinking at the intermediate level. (YP)

A teacher describes the experiences of her fourth-grade students when using calculators during mathematics class. (MK)

Several activities are described for students at different elementary grade levels. Some involve estimation of quantities, and others include reasoning about permutations and combinations. (SD)

The author presented young children with reasoning problems. Summaries of performance on diverse problems are presented. (SD)

Compares two approaches to the teaching of mathematics, rote versus reasoning. Discusses the way to teach mathematics as reasoning in elementary classroom as stated in the NCTM Standards. (YP)

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)

Presents a variety of examples through which kindergarten and primary grade children can engage in significant problem solving. The suggested activities use materials in a problem solving context to permit children to experiment, to create, and to make measurements. (PK)

Described are activities involving higher order thinking skills developed for gifted students that can be used for all students. Discussed is a framework for designing activities using Bloom's Taxonomy of the Cognitive Domain and William's Student Behaviors. Sample activities are included. (KR)
