Three worksheets provide exercises involving triangular arrays of numbers. (SD)

Several problems involving "pi" and "e" can be approached by diagramming, flow charting, and computer programing. (SD)

A model for multiplication is described and used to discuss the properties of division. (SD)

Homemade geostrips, "angle-fixers" (cardboard circular sectors) and brass fasteners can be used by students to explore properties of angles, triangles and other polygons. Several games and other activities are suggested. (SD)

Students, playing the game described, develop strategies for guessing the four-digit number chosen by the opponent. The rules of the game are easily understood by low achievers, yet strategy development is challenging to advanced students. The game can be extended to numbers having more digits. (SD)

Wooden cubes can be used with task cards and teacher-made materials to develop and reinforce learning of linear measurement, area and multiplication, volume and surface area. Students can use cubes to cover area and fill boxes; later they learn to make boxes to fit specified numbers of cubes. (SD)

Over the past few years a substantial body of research has yielded evidence that the semantic structure of elementary arithmetic word problems influences children's strategies to solve them. The study reported in this document considered three other task characteristics in addition to semantic structure: (1) the order of presentation of the two…

The focus of this booklet is on matching, recognizing, and identifying colors, shapes, and sizes. Concept development as well as vocabulary learning are goals. A variety of materials are used in the activities. Activities for children from preschool through grade 2 are grouped by topic. (MNS)

The first edition of the counting workbook centers around the numbers from 1 to 100 and focuses on number and set concepts.

Spaced throughout…

Decimal numbers have become an increasingly important topic of the elementary and junior high school mathematics curriculum. However, national and state education assessments indicate that students have incomplete and distorted conceptions of decimal numbers. This paper reports initial data from a two-year project designed to elicit and describe…

The manual lists program objectives for the math curriculum at Kendall Demonstration Elementary School for hearing impaired students, objectives are grouped by age (preschool: grades 1, 2, 3, 4, 5, and 6).
