In a two-year study, frequencies and descriptions of systematic errors in four algorithms in arithmetic were studied in regular and special education classrooms. (Author/SD)

Implications for teaching the metric system to educable retarded students are discussed. (CL)

The effect of the use of hand-held calculators on the arithmetic curriculum is explored. (SD)

In the situation described, the withholding of immediate reinforcement led a student to verify his method, and thus led to greater confidence and motivation. (SD)

A learning activity relating modular arithmetic to patterns of figures determined by points equally spaced around a circle is described. (SD)

Students who were unsuccessful in performing long division were taught to use a successive subtractions algorithm. (SD)

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)

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)
