このクラスで学べること
1. Introduction (5 minutes)
• Welcome and Icebreaker: "What’s one thing you know about ancient Egypt?"
• Brief explanation of unit fractions and how they differ from other fractions.
2. Egyptian Fractions Overview (10 minutes)
• What Are Unit Fractions?
o A unit fraction has a numerator of 1 (e.g., 1/2, 1/3, 1/4).
o The Egyptians only used unit fractions in their math.
• How Did They Do It?
o Explain how Egyptians expressed fractions like 2/3 as the sum of unit fractions (e.g.,
2/3 = 1/2 + 1/6).
o Show examples from the Rhind Mathematical Papyrus.
3. Hands-On Activity: Writing Modern Fractions the Egyptian Way (15 minutes)
• Interactive Exercise:
o Give students a fraction like 3/4 or 5/6.
o Guide them step-by-step to express it as the sum of unit fractions (e.g., 3/4 = 1/2 +
1/4).
o Use visuals or manipulatives like fraction circles or bars to help them “see” the sums.
• Group challenge: Solve problems collaboratively (e.g., share 5 loaves of bread among
6 people the Egyptian way).
4. Math Meets History: A Fun Story (10 minutes)
• Share a short story about how ancient scribes used fractions in daily life (e.g.,
dividing bread, distributing goods).
• Connect their methods to modern ideas like fair division and proportionality.
5. Wrap-Up and Takeaway Challenge (5 minutes)
• Recap Key Ideas:
o Unit fractions and their role in Egyptian math.
o How to write modern fractions as sums of unit fractions.
• Takeaway Challenge: Ask students to find another fraction (e.g., 7/8) and represent it the Egyptian way at home.
________________________________________学習到達目標
• Understand the concept of unit fractions (fractions with a numerator of 1, like 1/2, 1/3, 1/4).• Learn how the Egyptians represented and used unit fractions in their calculations

教師の専門知識と資格
As a self-taught learner with a deep love for math, science, English, foreign languages, and history, I've spent my life diving into a wide range of subjects. I believe that learning can happen anywhere and at any time, which is why I enjoy sharing the tools and strategies I’ve developed over the years with students of all ages.
While I welcome all learners, I specialize in working with neurodivergent students or those who thrive with different learning approaches. As someone who is neurodivergent myself and a parent to a neurodivergent child, I understand firsthand the unique challenges and strengths that come with thinking differently. My goal is to create a supportive, engaging, and flexible learning environment where every child feels empowered to explore and succeed in their own way.
I majored in Applied Mathematics/ Computer Science minoring in foreign languages in addition I have worked with most types of learners including neurodivergent ones.
