Specifically, the study tried to answer the question" What is the effect of using Montessori Method in developing the creative thinking skills in math course for the third class students in Nablus Governorate"?.

The Simi-Experimental Design was adopted in this study. Furthermore, the sample size consists of 58 students from Al Rawada Secondary School, and the sample was divided into two groups; experimental group and control group. Montessori Method was applied for the experimental group, while the traditional methods were applied for the control group.
