This study was purposed to describe effect of using innovative learning models for mathematical thinking high school students in Palembang. In this research, mathematical thinking only focus on aspect abstraction and representation. This study was experimental research. The data collection used test and interview. The data analysis used two ways anova. Based on the data analysis, the conclusions is there were no differences in the mathematical thinking between students who worked under creative problem-solving (CPS) and problem-based learning. Based on analysis students- solution, most of students used numeric and algebraic representation, and few students used visual and symbolic representation. Besides that, from abstraction aspect, most of student do specialization, observation of pattern and generalization.
