Identifying important aspects of mathematical thinking was one of the main goals of that study. A mathematical thinking model was developed with the help of expert opinion, such as curriculum designers, mathematicians and teacher trainers, and then this model was presented to practicing teachers and teacher trainers for their opinions. There was a significant response in favor of the mathematical model. Therefore, the final model which included generalization, induction, deduction, problem solving, logical thinking, and mathematical proofs. This result was important for developing a mathematical thinking model with relevant aspects of mathematical thinking and thus obtaining an accurate relationship with mathematics achievement. Finally, six aspects of mathematical thinking were identified in this study: deduction, generalization, induction, problem solving, logical thinking, and geometric proofs. Most teachers 80% of teachers agree that these six aspects are the most important and relevant to the mathematics textbook curriculum. From the above discussion, we have almost arrived at the aspects of mathematical thinking: deduction, induction, logical thinking, generalization, mathematical proofs, and problem solving. Literature related to each aspect of mathematical thinking is presented
