❓공식은 외웠는데, 왜 문제는 못 풀까요?
시험지를 앞에 두고 멍하니 있는 아이.
공식은 외웠지만, 손이 안 움직입니다.
그 이유는 ‘이해’ 없이 외운 공식은 스스로
문제를 풀게 해주지 않기 때문입니다.
특히 소금물 농도 문제는
단순히 식을 외운다고 풀리지 않아요.
이 지점에서 수학을 놓아버리는
아이들이 생각보다 많습니다.
🔄 공식 없이, 원리로 푸는 소금물 문제 수업
이 수업에서는 공식과 방정식 없이,
사칙연산만으로 문제를 해결하는 법을 배웁니다.
아이의 눈높이에 맞춰 문제를 해석하고
숫자의 의미를 하나씩 짚어나가며
문제의 구조를 이해하는 힘을 길러줍니다.
👶 “이해했다”는 말,
그 순간 수학이 다시 시작됩니다
초등학생도 이해할 수 있도록 설명하지만,
그 결과는 중학생이 먼저 반응합니다.
복잡한 용어 대신 문제 속 문장을 차근히 읽고,
"그래서 이렇게 풀면 되는 거구나!" 하는 경험을 하게 되죠.
이해가 쌓일수록, 아이는 자신의 힘으로
문제를 풀 수 있다는 감각을 갖게 됩니다.
그리고 그 감각은 자신감이 되어 돌아옵니다.
🧭 수업은 이렇게 진행돼요
문제를 말로 설명하면서 구조를 파악합니다
사칙연산만으로도 충분히 풀 수 있다는 걸 직접 느낍니다
기존의 공식 풀이와 비교하며, 이해 기반 풀이의 장점을 체험합니다
반복 연습을 통해 이해력이 점점 깊어집니다
💕 ‘외우는 수학’이 아니라
‘생각하는 수학’을 가르칩니다
‘왜 이렇게 푸는지’를 스스로 설명할 수 있게 합니다
수학 문해력과 사고력을 함께 키웁니다
수학을 포기했던 아이도 다시 도전할 수 있는 계기를 만듭니다
💡 아이의 수학 자존감을 회복하는 수업입니다
급하게 성적을 올리기보다,
아이 스스로 문제를 이해하고
풀 수 있는 기초 체력부터 다집니다.
👉 지금, 수학을 다시 시작할 수 있는 기회를 만나보세요.

Hello! I am Teacher Im Ji-woo, dedicated to researching and practicing classes that foster a child's "thinking power." 😊 I believe that a child who can ask questions on their own, organize their thoughts, and explain things in their own words is a child with true ability, rather than simply a child who is good at solving problems. Therefore, rather than teaching only "knowledge," I naturally cultivate the cognitive abilities that form the foundation of learning (attention, memory, thinking skills, and execution skills) through teaching aids, challenges, and lessons. 📚 Qualifications and Professional Courses - Completed the Wechsler Intelligence Test Expert Course - Completed the Level 2 Cognitive Learning Psychology Counselor Certification Course 🧡 Recommended for these types of children! ✔️ Children who can solve problems but lack understanding ✔️ Children who struggle to read, summarize, or grasp the main points ✔️ Children who lack study habits or confidence ✔️ Children who want to try math in a new way Classes that build your child's thinking muscles, Start your journey with Teacher Jiwoo! 🧠✨

My 4th grader is a humanities-oriented student who rushes ahead with advanced topics rather than focusing on in-depth study. While studying concentration, my child managed to memorize the formulas somehow, but would get intimidated and feel at a loss when it came to solving word problems involving systems of inequalities and equations by substituting values into the problem. However, I was amazed to see my child solve those problems effortlessly after taking your class! First off, your voice is very clear and easy to understand. You provide concise tips tailored to an elementary student's level that can be applied immediately without any difficulty. My child says that concentration problems won't be difficult anymore! I would love to take your distance, speed, and time class if it becomes available, and I plan to take your other classes as well. ^^

I wasn't feeling well, so I missed my scheduled time to get with my child and ended up joining in the middle. By the time I arrived, we were already at question number 17, so my child found it difficult to understand. However, as an adult, I was able to grasp it, so I explained it to them again after class. It would have been great if I had listened from the beginning; that one thing was regrettable because of my mistake. The teacher explained everything very diligently, and I am looking forward to the class on Distance, Speed, and Time next week. I won't be late then! The correct answer to question number 4 is 10%.

Last time, my child attended the class with a blank slate, but after the lesson, was able to solve all the problems on the worksheet. I really felt like it was the ultimate secret method~^^ However, my child forgot it over the past few months, so we took the class again... You make it easy to understand but ensure it is clearly grasped, tailored to the children's level. Even the teacher's voice was very concise and clear, making it easy for the children to focus on the lesson. Also, perhaps because you kindly encouraged questions, even my child, who is extremely self-conscious, asked questions several times. Thank you for the great class.^^
