The aim of this paper is to see how level-based work sheets affect the students in their learning mathematics. To study the effects, level-based work sheets were given in accordance with the students' academic achievements in two groups, sampling class and random class. For more precise clarification, each class was classified in three groups: A, B, and C. Studying these groups revealed the following results. 1. The students given the level-based work sheets in accordance with their achievements in the sampling class have made remarkable progress in their learning attitudes than the 'A' group in the sampling class. 2. The meaningful difference of the two classes in their average scores of mathematics, before and after the study, turned out to be 5%. According to pass the time, between the two classes, the difference of average scores appeared to be the same: that is, 5%. Also this survey showed that the students in the sampling class were more active and positive in their subsequent study.
