The abacus is a calculating tool that has been used in Asia for thousands of years. Mental abacus calculation is a skill in which an abacus image in the mind is used without the actual physical manipulation of the abacus. Using this method, people can perform extremely rapid and accurate mental calculations. Research indicates that abacus training…

Seriation refers to the process of ordering objects along single or multiple magnitude dimensions such as length, weight, and color. The ability to order objects in terms of some attribute is essential for the child's understanding of the properties of numbers. This study investigated the effect on seriation performance of increasing both the…

Thirty-six studies on individualizing instruction in arithmetic are reviewed, and the general findings emerging from the combined research are discussed. (SD)

Using arrays of dots and grids many numerical concepts can be illustrated for students. (SD)

A game involving operations on whole numbers, observing patterns in the relationships between operands and results, and seeking problems yielding various numerical solutions is described. (SD)

Many concepts can be introduced informally through activities. Among those which can be investigated using easily-made 10-by-10 pegboards are geometric shapes, coordinate systems, grouping and regrouping, and addition of two-place numbers. (SD)

Fourth-grade students and their parents attended evening mathematics classes together. Parents and students helped each other in solving arithmetic problems. Scores of students on a posttest were significantly better than on a parallel pretest. (SD)
