Hello! I am Kim Ha-young, a math teacher at Kookgeu. How can one excel at math? Is it enough to simply solve many problems or memorize concepts and formulas? While both methods may help improve math grades, they are not the fundamental solution. Mathematics is a subject about understanding concepts and principles and developing critical thinking skills to apply them to problem-solving. This is because even problems that look difficult and complex, or types of problems seen for the first time, can eventually be solved by identifying the core concepts and connecting them one by one. My curriculum aims to help students develop their ability to think independently, starting with easy problems and progressing step-by-step, by understanding concepts and principles and applying them to problems. I also select high-quality textbooks that are primarily used in Daechi-dong. Furthermore, I share the progress of every class with parents and have systematized periodic tests and reviews. **Koogeu** To learn properly the first time, let's focus on the parts important for the exam rather than rushing ahead, and build our math skills efficiently rather than by speed!
