"Anyone can meet math easily and enjoyably." Hello, I am Jung Bo-young, a Kookoo Hero instructor. There are many ways to learn math. Which method should we choose? Math is a subject like a long marathon that must be sustained from early childhood until the day college entrance exams end. There are many academies that select and teach only the high-achieving students. However, children need teachers who not only help them develop their skills but also encourage them to study math diligently and guide them persistently until the very end. From students who find math difficult and boring to those with top-tier skills, all children can learn math with enjoyment. Math classes with Teacher Boyoung are truly fun. Based on my experience developing math programs and textbooks and teaching children for over 20 years, I present "flexible methods" tailored to the children's levels. I conduct classes by "communicating" with the children by listening to their answers rather than giving one-sided explanations, and by teaching them how to "tackle problems and solve them on their own." It will be the best class where children can discover the charm of mathematics.
