This study aims to improve creative thinking skills and problem solving skills through the synectic learning model in mathematics lessons for X grade students of SMA PGRI 2 Makassar. This research is classroom action research (CAR) with the research subject being class X SMA PGRI 2 Makassar in the odd semester of 2021/2022, totaling 10 students. Data retrieval was carried out using a test of the results of creative thinking in learning mathematics at the end of the cycle and observation sheets carried out every time the learning process took place. The data collected were analyzed using quantitative analysis. The results showed that the average score of students' mathematics learning creative thinking results in the first cycle was 60.60 and the standard deviation was 6, 489 then in the second cycle, the average score of students' mathematics learning creative thinking results was 77.40 with a standard deviation of 8.002. The completeness of the results of creative thinking in classical mathematics learning in the cycle is 10% and in the second cycle there is an increase of 90%. From the results of this study, it can be concluded that by applying the synectic learning model there is an increase in students' creative thinking in learning mathematics.
