In this research the efect of usage of Cube Model in the teaching of Pascal triangle and some identical equalities has been investigated. The research was carried out on two groups one of which was experimental group and the other traditional learning group, both from 8 th grade of an elementary school in Diyarbakýr. In the research in which the pre- test post - test control group was used, Pascal triangle and some identical equalities beging in the unit named Lettered Expressions and Equations in the eight class program was taught in the science laboratory in the group study with open ended question for two hours. In the analyses of the data obtained in the research, some statistical methods such as T-test, percentages, and frequency were used. It was observed that experimental group learned significantly more than the control group.
Key words: Teaching Mathematic, Identity, Pascals Triangle, Cube Model
