초등학교 5학년 1학기 핵심 단원인 ‘약분과 통분’을 쉽고 체계적으로 복습하는 1회성 수업입니다. 학생들이 가장 헷갈려 하는 ✔ 약분의 의미와 방법 ✔ 통분이 필요한 이유 ✔ 분모를 같게 만드는 원리 ✔ 분수 크기 비교와 계산 기초 를 이해 중심으로 쉽고 재미있게 설명합니다. 단순히 문제를 푸는 것이 아니라, “왜 이렇게 계산하는지”를 이해하며 배우기 때문에 분수에 대한 자신감과 응용력을 함께 키울 수 있습니다.

🧩 이 수업을 들은 후 달라지는 점
약분과 통분의 개념을 스스로 설명할 수 있어요
분수 계산 문제를 볼 때 “왜 이렇게 푸는지” 논리적으로 접근해요
여러 분수의 크기를 비교하고, 자신 있게 계산에 도전해요
모든 분수 문제를 두려워하지 않고, 다음 단원에서도 자연스럽게 응용해요
✏️ 수업 내용 3줄 요약
약분과 통분의 필요성부터 방법까지, 이해 중심으로 정리해요
직접 문제를 풀어보며, 자신이 부족한 부분을 스스로 알게 돼요
분수 크기 비교와 계산 기초까지 마스터하며 응용력도 챙겨요

🌈 이런 친구에게 자신 있게 추천해요
5학년 1학기 분수 단원이 헷갈리거나 아쉽게 끝났던 친구
약분, 통분의 차이와 원리를 제대로 이해하고 싶은 친구
분수 계산이 나오면 막막해지는 아이
개념 복습과 실전 문제 적용, 두 마리 토끼를 한 번에 잡고 싶은 친구
💡 분수 계산, 어렵게 느껴졌나요?
이 수업은 분수를 ‘그냥 푸는’ 것이 아니라, “도대체 왜 이렇게 풀어야 할까?”라는 질문에 답을 찾을 수 있도록 만들었어요. 예를 들어, 약분은 답을 구하기 위한 스킬이 아니라, 분수의 진짜 모습을 알아내는 열쇠라는 것도 스스로 깨닫게 해요.
낯설었던 분수 개념과 친해지는 80분, 부담은 줄이고 개념 자신감은 크게 올릴 수 있는 시간이 될 거예요!
⏰ 80분, 수업은 이렇게 흘러가요
인사 및 안내 (5분)
약분, 통분의 원리와 실전 적용 방법을 포함한 개념 설명 (20분)
프린트 풀기(단순 연산 10분제, 문장제 문제 10문제) (20분)
분수 계산 문제 풀이, 오답 풀이 (20분)
유형별 문제 풀이 (10분)
오늘 배운 내용 정리 마무리 (5분)
Great for These Kids
분수 계산이 어려운 학생

💻 Immersion that bursts through the screen! A 13-Year Veteran Elementary Teacher’s Integrated Class 🚀 Hello! I am "Teacher Beom," the Yoo Jae-suk of the education world, who captures both the fun and depth of online classes! 👋✨ Were you worried, "Won't it be difficult for children to concentrate during online classes?" 🤔 With the know-how of a ZOOM teaching veteran solidly honed since the COVID-19 era, I present an immersion even hotter than face-to-face classes! 🔥 🎓 Who is Teacher "Teacher Beom"? 🏫 Former elementary school teacher in the Seoul area for 13 years (Currently a popular instructor in the private academy scene! 🔥), holds a Level 1 Elementary School Teacher Certificate (issued only to teachers with 5 or more years of experience). 🎓 Graduated from Seoul National University of Education, Department of Elementary Education. 📑 Master's degree from Korea University Graduate School of Education (Educational Administration and Higher Education). 🖥️ Expert in Online Education (ZOOM) Content and Operations. 🌟 What makes Teacher "Teacher Beom"'s class different? 🎬 1. 'Entertainment-style' immersive classes with no dull moments! 🥳 If a class isn't fun, students quickly get distracted in front of the monitor. My classes are as entertaining as a variety show! As children participate with smiles and unable to take their eyes off the screen, the class time flies by before you know it. Experience the magic of naturally asking, "Teacher, when is the next class?" 😉 🧠 2. Integrated 'Curriculum-linked classes' covering all subjects 📚 Math and critical thinking math are a given! I am an elementary curriculum expert who has perfectly mastered Korean, Social Studies, and Science. Rather than fragmented classes teaching only one subject, I maximize children's integrated thinking skills through linked lessons that cross subject boundaries. 📊📝 💡 3. Create your own 'problem-solving routine' to find the correct answer! 🛠️ Cultivate the power to connect the truly necessary core concepts among countless others. We guide students to avoid being confined to memorizing formulas or solving a single example, encouraging them to approach learning from various angles so they can independently develop their own study methods and problem-solving routines (such as calculations). 📊 A Perfect 'Close-knit Management System' Even Online ✏️ Non-face-to-face Cumulative Tests: We thoroughly review the material learned in the previous session before every class. 📈 Data-driven Solutions (Mathematics): We build systematic data sets by accumulating test results and provide personalized feedback and solutions tailored to each student. 🤝 Always Open 1:1 Counseling: You can share professional educational counseling at any time regarding not only subject knowledge but also concerns about school life and overall learning. 🎈 "I will be a mentor closest to your heart, not just a teacher inside a monitor." Experience the miracle of making studying fun in Teacher Beom's class right now! 👇✨
