A description is given of a sequence of activities, designed to explore the relationships between members of the parallelogram family, used with a sixth-grade class. (MK)

Presents three classification activities in which students work in cooperative small groups using physical materials to foster flexible thinking in doing mathematics. Concludes that attribute blocks are useful physical manipulatives for promoting classification activities and problem-solving skills. (ASK)

This book suggests creative, classroom-tested mathematics activities to teach number recognition and counting, number formation, sorting and classification, measuring (including time and date), shapes, graphing, estimating, ordinal positions, money, patterning, tallying, and fractions. Activities are presented in the forms of games, crafts, songs,…

Presents two activities on addition, one for classifying and one for symmetry. (ASK)

Various types of computerized sorting techniques are demonstrated with cardboard materials children can manipulate. Bubble, ripple, and binary sorting are each illustrated. (MNS)

Worksheets for duplication concerned with classification and measure of various geometric shapes are given. (MK)

The focus is on how reasoning can be developed through the study of two-dimensional shapes, their properties, and the relationships among them. Research on children's understanding of geometric shapes is reviewed and activities to develop analyzing and classifying skills are given, with a bibliography included. (MNS)

Provides instructions and worksheets for activities on: (1) sorting sets (grades K-one); (2) telling place values of two-/three-digit numbers (grades two-four); (3) recognizing multiplication/division facts (grades four-six); and (4) computing problems that contain multiples of 10, place value problems, and subtraction problems with many zeros…

Describes activities for developing pattern recognition and classification using worksheets. The objectives, directions, extensions, and bibliography are provided for each activity. (YP)

Presents a developmental taxonomy which promotes sequencing activities to enhance the potential of matching these activities with learner needs and readiness, suggesting that the order commonly found in the classroom needs to be inverted. The proposed taxonomy (story, skill, and algorithm) involves problem-solving emphasis in the classroom. (JN)

The purpose of this study is to contribute to an understanding of how errors could be employed in mathematics instruction so that the students use them constructively in support of their learning of mathematics. A teaching experiment was designed to create an ideal context in which the pedagogical approach to errors as springboards could be…

Describes an approach which helps sixth-grade students become excited about word problems. By using the approach (which involves categorizing a problem before solving it), students master skills in the problem and also develop more positive attitudes toward solving problems. The approach is equally applicable to any intermediate/junior high grade…

Presents a problem suggested for students in grades one through six concerning the concepts of grouping, reasoning, and pattern finding. Discusses the student problem-solving process. (ASK)

Reviewed is computer software on: (1) classification of living things, a tutorial program for grades 5-10; and (2) polynomial practice using tiles, a drill-and-practice program for algebra students. (MNS)

This monograph presents 13 papers dealing with various aspects of elementary problem solving. They are: (1) "Training for Effective Problem Solving" (Gary A. Davis); (2) "Patterns of Problem Solving--A Campus-Wide Course at UCLA" (Moshe F. Rubinstein, L. Robin Keller, Edward A. Kazmarek); (3) "A Taxonomy of Problem-Solving Activities and Its…
