The problem of this study was to determine if the mathematics achievement of selected second and third grade students is significantly improved by having had instruction in the Chisanbop technique. The purposes of this study were as follows: 1. To determine if the Chisanbop technique, when used in conjunction with a regular program of instruction, can significantly improve the mathematics performance of selected second and third grade students. 2. To determine if instruction by the Chisanbop technique is more effective with above average academic, average academic, or below average academic second and third grade students in improving mathematics performance. 3. To extend the body of knowledge with regard to the teaching of mathematics at the elementary school level.
